Answers
Answer:
2. The North frigid zone, between the Arctic Circle 66.5° N and the North Pole 90° N. Covers 4.12% of Earth's surface. The North temperate zone, between the Tropic of Cancer 23.5° N and the Arctic Circle 66.5° N. Covers 25.99% of Earth'ssurface.

3. The torrid zone has the maximum temperature as the heat rays of sun directly fall on this region .
4. The green wich mean time longitude is the name longitude used for measuring time all over the world .
5. Standard meridian selected by our country is 5.30 hours before gmt so it is easy to calculate time of the country .
E
1. Main characteristic of latitudes :
#They are partners to each other .
#They are horizontal imaginary lines that run from east to west on a globe
#Theer are 181 latitudes including equator
2. India has the vast longitudenal extension . Since many longitudes pass from it , it has to adopt a central longitude for local time to avoid confusion of time .
3.The most suitable heat zone for living is the Temperate zone as it has a good climate for crops as well as survival of animals and humans
4.The Earth rotates once a day, so that’s 360 degrees (the number of degrees in a circle) in 24 hours. If you do the math, that’s 360/24 = 15 degrees per hour. Each time zone is of course one hour, so there are 24 time zones of 15 degrees each.
The question is asking about minutes instead of hours, so we need to think of each time zone as having 15 degrees in 60 minutes. To solve for 1 degree, we divide 60 minutes by 15 degrees, so 60/15 = 4. In other words, it takes 4 minutes for each degree of the Earth’s surface to rotate past a fixed point in space.
5.The Equator separates the Northern and Southern Hemispheres. The Equator is at 0° latitude. The Prime Meridian separates the Eastern and Western Hemispheres. The Prime Meridian runs through Greenwich, England and is at 0° longitude.
6. There are two reference points on the Earth- the North Pole and South Pole.
