Whats the difference between a rain forest, a forest and a jungle?

Forests are different all over the world. Two things can help you determine what kind of forest you're looking at: the climate (warm or cold) and the kinds of trees you see. Some trees are called evergreens, because they never lose their green leaves or needles. Others are deciduous, which means their colorful leaves come tumbling to the ground each fall. Tropical rainforests are the richest, most productive ecosystems on Earth. Approximately 80 percent of the developed world's diet originated in the tropical rainforest. At least 3,000 fruits are found in the rainforests. Of these, only 200 are now used in the Western World while the indigenous peoples use over 2,000. The tropical rain forest is found around the equator where temperatures are about 25 degrees Celsius all year, and there is an average rainfall of 200 cm. Portions of South America, Central America, Central Asia, Australia and Africa are included in the biome. Because of the humid conditions, this biome has the greatest amount of plant growth. Large trees, last but not least; jungle [Hindustani jangal=desert, forest; from Skt. jangala=wasteland, uncultivated land], densest form of tropical forest (usually second growth or later) found throughout tropical lowland regions. Jungle is characterized by high humidity and resultant abundance (both in numbers and variety) of flora and concomitantly of fauna. Jungle is not a strict ecological term and is often applied to any impenetrable thicket or tangled mass of vegetation.

the amount of rain it gets annually, and its latitude.

Well, a forest is a place were there is lots of trees and has many common animals and a rain forest and a jungle has very rare animals and weird plants.
