Q

What is tropical zone?

A

The zone between the Tropic of Cancer and Tropic of Capricorn is called tropical zone because this zone receives immense amount of it throughout the year. That’s why any country or part lying in the zone will never have winter that’s why this zone is called tropical zone

Q

What is called and latitude?

A

Latitude is the distance on the Earth surface north or South of the equator expressed in angular measurement is 0° and equal to 90°. In simple words latitudes are the parallel lines running from east to west or vice versa.

Q

What is the longitude?

A

Longitudes are the imaginary lines which ran from poles to poles. These are not the parallel lines. The distance between the two longitude increases as one move from poles to equator. The distance between two longitudes is maximum at equator and minimum at the poles.
