2. Globe: Latitudes & Longitudes

Question 1

What is the axis of Earth?

Answer 1

The imaginary straight line passing through the north pole and the South Pole about which the Earth rotates from west to East.

Question 2

What are the parallels of latitude of Earth?

Answer 2

The equator is an imaginary line that divides earth in the Northern and the southern hemispheres. All circular lines parallel to the equator are called parallels of latitude. They are measured in degrees.

Question 3

What are North latitudes and South latitudes?

Answer 3

All parallels of latitude north of the equator are called North latitudes and all parallels of latitude south of the equator are called South latitudes.

Question 4

Which are the important parallels of latitudes?

Answer 4

Equator: 0°
North Pole: 90°N
South Pole: 90°S
Tropic of Cancer: 23°30’N
Tropic of Capricorn: 23°30’S
Arctic Circle: 66°30’N
Antarctic Circle: 66°30’S

Question 5

What are the heat zones of Earth?

Answer 5

Torrid Zone: The region between Tropic of Cancer And the Tropic of Capricorn.
Temperate zones: The region between the Tropic of Cancer and the Arctic Circle and the region between the Tropic of Capricorn and the Antarctic circle.
Frigid zones: The region between the Arctic Circle and the north pole and the region between the Antarctic circle and the South Pole.

Question 6

What are longitudes?

Answer 6

The imaginary semi circular lines joining the north pole and the South Pole along the surface of the earth are called latitudes.

Question 7

What is the Prime Meridian?

Answer 7

The longitude passing through Greenwich in the United Kingdom, which is also home to the British royal observatory, is called the zero degree longitude or also called as the Prime Meridian.

Question 8

How much is a 1° longitude in time?

Answer 8

15° per hour
1° per 4 minutes

Question 9

Describe the longitude expanse of India and the Indian Standard Time longitude.

Answer 9

Expanse: 68°E to 97°E
IST: 82°30’E or 5.5 hours ahead of Greenwich Meredian Time
