Why are tropical rainforest near the equater?

Answer 1

The region around the equator is the tropics (both north and south), so any rainforest around the equator which is in the tropics is a tropical rainforest.

A rainforest can exist (and does exist) outside the tropics. The Pacific Northwest, for example, has the Hoh rainforest.

A "tropical rainforest" is typically hot year round with little temperature change from month to month.

Tropical rainforests are near the equator because the climate there is warm, very wet and constant due to the position of the sun over the equator; it's always directly overhead. The plants that live there thrive in these conditions. There are only two seasons in the tropical rainforests: wet season and dry season.

The rainforests are so wet because whenever it rains, the water collects on the big leaves of the trees and evaporates quickly, forms into clouds and rains down again.

Answer 2

The temperature around the equator are always high/which causes a fast evaporation of water.

Answer 3

Because it is warmer and wetter there.
