OUR ENVIRONMENT<br />

Map Literacy<br />

Map skills are a part of visual<br />

literacy — a set of skills to “read” and<br />

understand images. Can you read maps<br />

and use the information to solve a<br />

problem? I suspect the answer will be no<br />

or not confidently. In this chapter we<br />

explore the skills needed to read and<br />

interpret maps.<br />

Maps are resources that allow you to<br />

explore the immediate and distant<br />

environment. They have information that<br />

comes in the form of images and<br />

symbols. If you can interpret (decode) the<br />

images and understand them you can use<br />

them to make sense of your world. The<br />

secrets to understanding world time, the<br />

reasons for the seasons in different parts<br />

of the world and communicating the exact<br />

location of any place on earth are<br />

available when you are map literate.<br />

Additionally, we focus on your visual<br />

literacy and higher-order thinking skills —<br />

to take you into a deeper exploration of<br />

the planet you inhabit. How does this<br />

knowledge help you to read and<br />

understand the real world? Well, included<br />

are map conventions — the cardinal<br />

points, how to use a key, scale, map<br />

symbols, latitude and longitude and<br />

regions connected to seasons, and how<br />

to locate cities and countries. Where do<br />

you fit in? Let’s begin with the Cardinal<br />

Points.<br />

THE CARDINAL POINTS<br />

DIRECTION COMPASS<br />

GRENADA<br />

You are now on a quest to gather<br />

information that takes you beyond the<br />

borders of the Caribbean. It is important<br />

to continue to be guided by the four<br />

Cardinal Points that are East, West,<br />

North, and South. Keep in mind that on


3<br />

most maps, the right side is always East;<br />

the left side is always West; the top is<br />

always North and the bottom is always<br />

South.<br />

EXERCISE 1<br />

First, look closely at the image and symbols on the Map of Trinidad. Next, answer the<br />

following questions based on the map.<br />

(1) On which coast is Blanchisseuse?<br />

(2) Moruga is located on the<br />

_________________ Coast.<br />

(3) Pointe-a-Pierre is located on the<br />

______________ Coast.<br />

(4) The Nariva Swamp is on the East<br />

Coast. True or False<br />

(5) Which coast is longer, the North or the<br />

South Coast?<br />

(6) To which coast does the Ortoire River<br />

flow?<br />

(a) North (b) East (c) West (d) South<br />

(7) On which side of the island would you<br />

find the Gulf of Paria?<br />

(8) If I travel from Port of Spain to San<br />

Fernando, I travel mainly in a<br />

__________________________<br />

direction.<br />

(9) Arima lies to the West of Port of Spain.<br />

True or False<br />

(10) What is the direction of Flanagin<br />

Town from Couva?


4<br />

COMPASS DIRECTIONS<br />

Initially, men used landmarks such as<br />

the stars and the sun to identify the<br />

direction in which to travel. The first<br />

compass-like device was invented in<br />

China when people in ancient China<br />

discovered that if a lodestone (stone with<br />

magnetic properties) was suspended so it<br />

could turn freely, it would always point<br />

toward the magnetic poles. This<br />

‘compass’ was first used to assist with<br />

finding the best areas for building Chinese<br />

homes (geomancy).<br />

Compasses were later adapted for<br />

navigation. The Compass is an instrument<br />

that shows the direction of the Magnetic<br />

North. On the Compass there are many<br />

points of direction but at our level we<br />

concern ourselves with the Main Cardinal<br />

Points; East (E), West (W), North (N) and<br />

South (S) and the Intermediate Points: -<br />

North East (NE), North West (NW), South<br />

East (SE) and South West (SW). The<br />

compass gives us a specific vocabulary<br />

with which to give and discuss directions.<br />

An actual compass is a very useful<br />

instrument to pilots, navigators, hikers,<br />

deep sea divers and mountain climbers. It<br />

helps them to plot their course of direction<br />

and to find their way around. The Cardinal<br />

Points are also important to every citizen<br />

in a country as one can determine the<br />

routes to places of interest.<br />

COMPASS DIRECTIONS


5<br />

How it Works:<br />

The Quan Island<br />

Imagine you are standing at Town “Y” and<br />

looking towards Town "X". The arrow<br />

shows the direction in which you are<br />

looking. This lines up with the<br />

intermediate cardinal point of South West.<br />

If you are uncertain, draw an imaginary<br />

cross at "Y", shown by the dotted lines.<br />

The arms of the cross represent the<br />

Cardinal Points.<br />

You can now declare, “Town “X” lies to the South West of Town “Y”.<br />

EXERCISE 2<br />

Look at the map of Trinidad on page 2, and answer the questions in your exercise<br />

book.<br />

(1) In what direction does Couva lie from<br />

Sangre Grande? ______________<br />

(2) From Moruga, in what direction does<br />

San Fernando lie? ______________<br />

(3) In what direction does Moruga lie from<br />

Couva? _____________________<br />

Complete the following sentences:-<br />

(4) Siparia lies to the __________ of Rio<br />

Claro.<br />

(5) Caroni Swamp is __________ of the<br />

Nariva Swamp.<br />

(6) From Chaguanas, Arima lies to the<br />

__________<br />

(7) From Couva, San Fernando lies to the<br />

__________.<br />

State whether the following are True or<br />

False.<br />

(8) The Caroni River flows to the East<br />

coast<br />

of Trinidad. __________<br />

(9) Moruga lies to the West of<br />

Guayaguayare. __________<br />

(10) Mayaro Bay lies to the South of<br />

Manzanilla Bay. __________

USING A REAL COMPASS<br />

Learning how to use a compass and a map reduces the chances of getting lost in the<br />

wilderness.<br />

What you’ll Need:<br />

• Orienteering-style compass with degree markings<br />

• Map of your local area or area of interest<br />

How to Use a Compass:<br />

1. To align a compass, read the directions for the compass and learn which end of the<br />

needle points north.<br />

2. Turn the compass until the north arrow on the compass’s face is aligned with the<br />

north end of the pointer. You are now aligned “north.” Observe the letters on the<br />

compass: N is north, E is east, S is south, W is west. Northeast, southeast,<br />

southwest, and northwest may also be present.<br />

3. Next, look at and record the numbers. These are degrees, another form of<br />

measuring compass direction.<br />

4. Turn and face any direction. Hold one hand out flat and place the compass on your<br />

palm. Point the arrow on the base plate in the direction you’re facing.<br />

5. Turn the dial on the compass until the north-facing arrow is aligned with the pointer.<br />

Now read the degree mark that the index line crosses. This is your direction in<br />

degrees.<br />

6. To find your bearing, place the map on the ground and find where you want to start<br />

and end. Place the compass so that it matches both points. Turn the dial until “north”<br />

points the same direction as the north indicator on the map. The index on the base<br />

plate should now line up with the correct bearing on the dial. Turn the compass in<br />

the correct direction.<br />

SEVEN CONTINENTS - FIVE OCEANS<br />

Compared to the countless stars and<br />

planets which make up the universe, the<br />

earth is less than the size of a needle<br />

point. However, to us its inhabitants, this<br />

is a very huge home. There are very large<br />

masses known as continents and<br />

immense water bodies known as oceans.<br />

We consequently have seven<br />

continents and five oceans on planet<br />

earth. It is only fitting that as global<br />

citizens you should know these basic<br />

facts. Jesus Christ is Lord!<br />

Listed below are the seven continents and five oceans on planet earth.<br />

The Seven Continents of the World<br />

Continents are large land masses<br />

made up of many countries. Countries<br />

which share the same land mass as each<br />

continent are designated as being part of<br />

the closest continent. These are those<br />

many smaller land masses which are<br />

surrounded by water which we call islands<br />

with each usually being one country. (Like<br />

the islands of the Caribbean)<br />

The seven large largest land masses or<br />

THE FIVE OCEANS<br />

The large expanse of salt water that<br />

covers three-quarters of the earth’s<br />

surface is truly one large ocean. However,<br />

this interconnected body of salt water has<br />

divisions which have the continents, or<br />

the equator, and other imaginary lines as<br />

their boundaries.<br />

SEAS<br />

A sea, on the other hand, is a body of<br />

salt water that is surrounded by land on<br />

all or most sides; they are however, part<br />

of one of the oceans. Note especially that<br />

sea and ocean refer to different bodies of<br />

water. Look at the globe showing the<br />

continents and oceans. Find the<br />

Caribbean Sea; note how the water<br />

seems to be surrounded by the<br />

archipelago of islands. Major seas include<br />

the Mediterranean, Baltic, Bering, Black,<br />

Caribbean, Coral, North, Red, and Yellow.<br />

ACTIVITY<br />

(Locate the seas mentioned above in your<br />

Atlas and see if the definition holds true<br />

for them. Pose any questions you have to<br />

your teacher and peers.)<br />

THE FIVE OCEANS<br />

The five major oceanic divisions are<br />

defined with reference to their location to<br />

the continents, various archipelagos, and<br />

other criteria. Make connections to the<br />

continents as you learn the names<br />

and locations of the oceans.

LINES <strong>OF</strong> LATITUDE AND LONGITUDE<br />

Knowing the location of the earth’s<br />

seven continents and five oceans is<br />

valuable information to apply as we<br />

explore the skills needed to ‘locate’ a<br />

place. Your home address identifies your<br />

‘local’ position. However, every place on<br />

earth has an absolute location identified<br />

through the use of lines of latitude and<br />

longitude. The absolute location of a<br />

place doesn’t change. These are the<br />

concepts (ideas) which we now explore.<br />

The local location or address of the<br />

Central Bank (Twin Towers) in Port-of-<br />

Spain is Independence Square Port of<br />

Spain, Trinidad and Tobago. This address<br />

is in relation to the many other buildings<br />

located in this general area. In contrast, to<br />

state that it lies at 10°38'55.1"N<br />

61°30'44.6"W is to pinpoint a position at<br />

which only the Central Bank is located<br />

(absolute).<br />

Among the things you observe when<br />

you look at a globe is that there is an<br />

overlay of lines that create a grid on the<br />

earth. This grid is known as a graticule.<br />

Those lines drawn in a North-South (sky<br />

to earth) or vertical direction are called<br />

lines of Longitude. The others drawn in an<br />

East-West or horizontal direction are<br />

called lines of Latitude.<br />

Traditionally, both lines of Longitude<br />

and Latitude are measured in degrees.<br />

They had been plotted many years ago by<br />

scientists and geographers. Though we<br />

see real lines they are only imaginary<br />

guide lines. These lines assist us to<br />

locate a place on Earth.<br />

LINES <strong>OF</strong> LONGITUDE


17<br />

Longitude lines are not parallel since<br />

they meet at the poles. There are 24 lines<br />

of Longitude and there were different lines<br />

of longitude being used as a starting<br />

point. However, a universal agreement<br />

was reached to designate one common<br />

longitude line as the PRIME MERIDIAN.<br />

This line at 0 o is the Greenwich Meridian<br />

or the zero degrees (0 o ) line of Longitude.<br />

It passes through the town of Greenwich<br />

in England.<br />

Now with 0 o being in the centre, the<br />

lines are identified by measurements to<br />

both the east and the west using zero<br />

degrees as their starting point.<br />

Consequently, we read eastwards from<br />

the 0 o line to the 180 0 line East Longitude<br />

and westwards from the 0 0 to the 180 0<br />

West Longitude. The 180 0 East and 180 0<br />

West Longitude line is the same line.<br />

The International Dateline<br />

THE TIME FACTOR<br />

Lines of Longitude are referred to as<br />

meridians (midday lines) because all<br />

places along any line of Longitude have<br />

midday (noon) at the same time. The<br />

180th Meridian directly intersects four (4)<br />

countries, and those countries could have<br />

had different time zones within their<br />

borders. They include Fiji, Kiribati, Russia,<br />

and the United States. The International<br />

Date Line follows part of the 180 o<br />

longitude line but diverts around these<br />

land masses to prevent such a confusing<br />

situation.


18<br />

LINES <strong>OF</strong> LATITUDE (parallels)<br />

Think about Hula Hoops of different<br />

sizes covering a ball. The largest hoop<br />

will rest at the centre, dividing the sphere<br />

into halves. On both sides we would<br />

need matching pairs of hoops to cover the<br />

ball totally. However, the one at the centre<br />

is the largest.<br />

both halves. All other lines of latitude run<br />

parallel to the equator; they never touch.<br />

Many years ago Eratosthenes of<br />

Cyrene, the ‘father of geography’, divided<br />

the globe into ninety (90) slices on either<br />

side of the equator.<br />

Hula Hoops and Ball<br />

LINES <strong>OF</strong> LATITUDE<br />

Now, imagine that the Hula Hoops are<br />

circles around the earth. These would<br />

represent the lines of latitude. The largest<br />

hoop that lies at the middle would<br />

represent the Equator. The equator is the<br />

main line of Latitude. If we were to cut the<br />

earth in half at the equator and place a<br />

large piece of paper in between the two<br />

halves, the paper would fit exactly onto<br />

Going north from the equator we find<br />

the Tropic of Cancer. This circle is located<br />

at 23.5 ° north. Continuing further<br />

northward we reach the Arctic Circle at<br />

66.5 ° north. Continuing all the way to the


19<br />

top of the Earth at 90 ° latitude we<br />

encounter the North Pole.<br />

If we journey southward from the<br />

equator we will find the Tropic of<br />

Capricorn at 23.5 ° south. Continuing<br />

south we reach the Antarctic Circle at<br />

66.5 ° south. Finally, at 90 ° south, we find<br />

the South Pole.

HEMISPHERES<br />

What are the hemispheres?<br />

The prefix ‘hemi’ means half while<br />

sphere means the shape of a ball<br />

such as the earth. Therefore, a<br />

hemisphere is any half of the earth.<br />

Geographers have divided the earth<br />

into four specific hemispheres<br />

(halves). They are paired as the<br />

Northern and Southern or Western<br />

and Eastern Hemispheres.<br />

The Northern Hemisphere includes all<br />

of North America, the northern parts of<br />

South America, about two-thirds of<br />

Africa, all of Asia excluding (parts of<br />

Indonesia) and all of Europe.<br />

The Southern Hemisphere<br />

NORTHERN AND SOUTHERN<br />

The equator (0 o Latitude) divides<br />

the earth into a Northern and a<br />

Southern Hemisphere. The Northern<br />

Hemisphere extends from the equator<br />

‘northwards’ to the North Pole and the<br />

Southern Hemisphere extends from<br />

the equator ‘southwards’ to the South<br />

Pole.<br />

The Northern Hemisphere<br />

The Southern Hemisphere includes<br />

most of South America, one-third of<br />

Africa, all of Antarctica, a small sliver<br />

of Asia (parts of Indonesia) and all of<br />

Australia/Oceania.<br />

The Northern Hemisphere has<br />

almost 90% of the land and the<br />

Southern Hemisphere has 90%<br />

water. Most of the world<br />

population lives in the Northern<br />

Hemisphere.

EASTERN AND WESTERN HEMISPHERES<br />

North and South America, which<br />

includes the Caribbean, Central<br />

America and Greenland.<br />

Naturally, the Prime Meridian<br />

which was selected to stand out, is<br />

used to separate the globe into vertical<br />

halves. From the Greenwich or Prime<br />

Meridian (0 o Longitude) eastwards to<br />

the 180 o East Longitude line is referred<br />

to as the Eastern Hemisphere. In a<br />

similar manner, from the 0 o Longitude<br />

to the 180 o West Longitude line is<br />

referred to as the Western<br />

Hemisphere.<br />

The Eastern Hemisphere includes<br />

most of Africa, about half of Antarctica,<br />

all of Asia and Australia /Oceania, and<br />

most of Europe.<br />

HISTORICAL FACT<br />

The Western hemisphere became<br />

politically and historically significant<br />

when Spain and England began<br />

explorations. The Eastern became “the<br />

Old World” and the Western “New<br />

World”.<br />

The Western Hemisphere includes<br />

about half of Antarctica and all of

LOCATE <strong>PLACE</strong>S USING LONGITUDE AND LATITUDE LINES<br />

Look at a globe and identify the 0 o<br />

Line of Latitude – Equator. It is the<br />

starting point for reading Latitudes.<br />

North and South Latitude lines are<br />

visible both to the right and left of the<br />

Equator. They increase at 10 o intervals<br />

up to 180 o . Next, locate the 0 o Line of<br />

Longitude – Prime Meridian. In the<br />

same way, East Longitude and West<br />

Longitude lines run on both sides of<br />

the Prime Meridian.<br />

Now, if the coordinates to a location<br />

are known then you may locate the<br />

specific place as follows. Latitude is<br />

read first followed by Longitude. Let us<br />

use the coordinates (30 o North<br />

Latitude, 90 o West Longitude). From<br />

the Equator, move upwards in a<br />

northern direction to find the 10 o North<br />

Line of Latitude. Next, from the Prime<br />

Meridian locate the 60 o West Line of<br />

Longitude. Our target location is at the<br />

point where these two lines ‘meet.’ If<br />

your finger landed on New Orleans,<br />

USA, you got it!<br />

It is to be noted however, that like<br />

other measurements there are<br />

intermediate points. With location, the<br />

units used are degrees, minutes and<br />

seconds. As a result, the coordinates<br />

can zero in on the location with the<br />

smaller units. For places that do not<br />

intersect exactly on two exact latitude<br />

and longitude lines the location may be<br />

40° 27' 30" N 117° 47' 30" W<br />

You would read it as 40 degrees 27 minutes 30 seconds North latitude and 117<br />

degrees 47 minutes 30 seconds West longitude.<br />
