3. The Standard Meridian of India is 82½º E longitude. True4. The length of Equator is 360º. False5. The Prime Meridian passing through the GreenwichObservatory is considered to be 0º.True6. The Prime Meridian is longer than all other meridians ofthe globe.FalseC. Fill in the blanks :1. The Earth is bulges out at the Equator and flattened at the poles.2. The distance between longitudes decreases towards poles.3. The network of latitudes and longitudes is known as the Earth's grid.4. The Arctic Circle is located in the northern hemisphere.5. The maximum distance between any two meridians is at the 0°.6. The value in degrees of the Prime Meridian is 0º.D. Match the following :1. The Equator cuts the globe (a) 66½ºS fo the Equator2. Torrid zone is also known as (b) 23½ºN3. Tropic of Capricorn lies at (c) into two equal halves4. Antarctic Circle lies at (d) 23½ºS5. Tropic of Cancer lies at (e) Tropical zone6. Arctic Circle lies at (f) 66½ºN of the Equator.E. Project / Activity :1. On an outline map of world, show the following :Tropic of Cancer, Arctic Circle, Standard Meridian, AntarcticCircle.Ans. (Do yourself)2. Find out the Standard time of the following countries withreference to GMT (Noon Time): Japan, China, India, NewZealand, South Africa.Ans. (Do yourself)F. Short answer questions :1. What is Equator?Ans. Equator is the imaginary line on the globe that divides earth intoNorthern and Southern Hemisphere.2. What are Meridians?Ans. The Globe has two set of circles. The circles run from north to southand pass through the North Pole and South Pole. These are called theMeridians.3. What do you mean by Earth's Grid?Ans. The parallels of latitudes and the meridians of longitudes form anetwork. These are called the Earth's Grid or the Geographic Grid.4. What is world time?Ans. The 0º meridian passing through Greenwich is the reference longitudefor International Time. The time according to the longitude of a placeis called local time.5. When was time zone system adopted?Ans. The system of time zone was adopted in 1884. Every country sets its6Horizon Press We 'n' Our Society – 6
time according to the time zone it falls. The Standard time of everyzone is set exact number of hours ahead or behind the GMT.G. Long answer questions :1. What are parallels of latitudes? Write there important featuresalso.Ans. The angular distance from Equator is measured as latitude. These linesrun between 0º and 90º latitudes in either hemisphere of Earth. Theseare called parallel of latitudes. Some important features of latitudesare:1. The Equator is the largest parallel.2. The latitudes are drawn from east to west.3. All latitudes are complete circles expect poles.4. All latitudes have equal distance from each other. The distancebetween two latitudes on the earth's surface is 111 km.5. The latitudes help us to locate places.2. What are heat zones? Write their names and respective positionon the Earth?Ans. All parts of the earth do not receive the same amount of solar energy. Itaffects difference in climate from one place to another. So parallelshelp us to divide the Earth into three heat zones.1.The Torrid Zone – This zone is the hottest part of the earth becauseit experiences the vertical rays of the sun. It lies between the Tropicof Cancer and Tropic of Capricorn.2.The Temperate Zone – The temperate zone are two in number.One in each hemisphere. They lie between 23½º and 66½º latitudes.These zones receive the slanting sun rays. So they are neither verycold nor two hot.3.The Frigid Zone – Beyond the Arctic Circle and Antarctic Circle, itis very cold as these areas receive extreme slanting rays of sun.These are the coldest regions.3. What is meant by local time? Which places on the earth have thesame local time?Ans. The time determined according to the longitude of a place is the localtime of that place. The local time to a place can be adjusted accordingto the mid-day sun. When a place is facing the sun, it is 12 Noon. Allthe places on the same meridian will have the same local time.4. Why does the Torrid zone receive maximum amount of heat?Ans. The word 'Torrid' means 'hot'. This zone is also known as Tropicalzone and lies between the Tropic of Cancer and Tropic of Capricorn. Itexperience the vertical rays of the Sun, at least twice a year. So thiszone is the hottest (Torrid) part of the earth.5. What is the difference between Indian Standard Time andGreenwich Mean Time?Ans. In India 82º 30'E (82½ºE) has been accepted as the standard Meridianfor the whole country. This time is Indian Standard Time (IST). TheIST is ahead of GMT by 5 hours 30 minutes.7Horizon Press We 'n' Our Society – 6
