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 />

(4) Siparia lies to the __________ of Rio<br />
Claro.<br />
(5) Caroni Swamp is __________ of the<br />
Nariva Swamp.<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 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 />
These slices are bounded by the lines<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

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 />

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 />
