It rains abundantly in rainforests because most rainforests are located around the earth's equator, which has a humid and warm climate. A forest must receive at least 75 inches of rain per year to be considered a rainforest.Continue Reading
Conventional wisdom attributes rainforests' considerable rainfall to warm, humid climates, but another theory suggests that forests are not rainforests because they receive a lot of rain; rather, they receive a lot of rain because they are rainforests which, by their nature, attract water that becomes rain.
According to this theory, a rainforest acts as a biotic pump, attracting water vapor. This water vapor condenses and turns to rainfall. In turn, the air pressure decreases, pulling in even more water vapor and driving the cycle. Not only does this theory suggest that forests are important to rainfall, but it also means that those rainforests are critical to the global water cycle.
Rainforests can be tropical or temperate. Both types receive at least 75 inches of rain per year, but temperate rainforests have cooler temperatures. Tropical rainforests lie in the equatorial regions of the world, particularly South and Central America, the Caribbean, Asia and Africa. Temperate rainforests are located farther north, in the Pacific Northwest.Learn more about Earth Science
The temperatures around the equator are always high, which causes a fast evaporation of water and results in frequent rain and a tropical climate. Rainforests are also located in temperate areas along the Pacific coast of the United States and Canada and in New Zealand, Ireland, Norway and Scotland.Full Answer >
The Earth rotates at about 1037 miles per hour at the equator, and the speed at the North Pole and South Pole is near zero. The speed of the Earth's rotation increases when approaching the equator and decreases toward the poles.Full Answer >
In tropical rainforests, the climate is usually hot and wet year-round. In temperate rainforests, average temperatures range from 40 degrees Fahrenheit up to the mid-50s.Full Answer >
Differences in the amount of sunlight hitting the earth cause the three main climate zones. However, weather varies within these zones. An area in the temperate zone, for example, can be warmer than an area in the tropic zone.Full Answer >
