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.Know More
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 equator is hotter than other areas of the earth, such as the poles, because it receives more direct sunlight than other areas. It is a common misconception that the equator is hotter due to it being closer to the sun than other areas of the earth. However, the earth's distance from the sun is so great that there really is no noticeable difference in distance from the sun.Full Answer >
The equator is important as a reference point for navigation and geography. It's an imaginary line that divides the Earth into two equal halves, and it forms the halfway point between the South Pole and the North Pole at 0 degrees latitude, according to National Geographic. It is also important because twice a year, during the spring and autumn equinoxes, the sun passes directly over it.Full Answer >
Scientists believe lunar tides help move heat from the equator to the poles, a pattern which brings cyclical warm and cool temperatures that create ice ages and assist with speciation among life forms. Tides force species to evolve because these relatively small coastal areas change rapidly. Without evolution, many marine species would have died out, and entire ecosystems may have been eliminated.Full Answer >
The tropical zone is an area located around the Earth's axis at the equator. It is limited to the Tropic of Cancer in the northern hemisphere and the Tropic of Capricorn in the southern hemisphere.Full Answer >
