All parallel circles from the equator up to the poles are called parallels of latitudes. The equator represents the zero degree latitude.
1. What is the true shape of the earth?
The Earth is a little flattened at North and South poles and its bulge is in the middle.
2. What is a globe?
Globe is a true miniature form of earth. A small model of our big Earth.
3. At what latitude Tropic of Cancer is located?
It is located at 23 1/2° N.
4. What are the three heat zones of the Earth?
The three heat zones of the earth are: Torrid Zone, Temperate Zone and Frigid Zone.
5. What are parallels of latitude and meridians of longitude?
Parallel of latitude are parallel circle from the equator up to the poles, Meridians of longitude are times of reference running from North Pole to South pole.
6. Why does the Torrid Zone receive maximum amount of heat?
The middle Sun is exactly overhead at least once a year on all the latitudes in between the tropic of Cancer and the Tropic of Capricorn. It, therefore, receives maximum heat and is thus called as Torrid Zone.
7. Why is it 5.30 pm in India and 12.00 noon in London?
India is located east of Greenwich at 82°30′ E, i.e., 5 hours and 30 minutes ahead of London. So it is 5.30 pm in India when it is 12 noon in London.
8. What is a axis?
There is a needle fixed through the globe in a tilted manner which is called its axis. The imaginary line passing through the centre of the earth and joining the two poles.
9. What is an equator?
An imaginary line running on the globe divides it into two equal parts. This line is called as Equator.
10. Mention some important parallels of latitude?
- Equator (0°)
- Tropic of Cancer (23½°N)
- Tropic of Capricorn (23½°S)
- Arctic Circle (66½°N)
- Antarctic Circle (66½S)
11. Define Torrid Zone.
The mid-day sun is exactly overhead at last once a year on all latitudes in between the Tropic of Cancer and the Tropic of Capricorn. This area is called Torrid Zone and receives maximum heat.
12. What is map?
Representation, on a place surface, of features of part of the earth’s surface drawn to some specific scale.
13. What is Prime Meridian?
It is first meridian, also called 0° longitude, which passes through the Greenwich in England.
