How much rainfall douse a forest get each year?

Answer 1

Tropical rainforests lie in the "tropics," between the Tropic of Capricorn and Tropic of Cancer. In this region sunlight strikes Earth at roughly a 90-degree angle resulting in intense solar energy (solar energy diminishes as you move farther north or south). This intensity is due to the consistent day length on the equator: 12 hours a day, 365 days per year (regions away from the equator have days of varying length). This consistent sunlight provides the essential energy necessary to power the forest via photosynthesis.

Because of the ample solar energy, tropical rainforests are usually warm year round with temperatures from about 72-93F (22-34C), although forests at higher elevations, especially cloud forests, may be significantly cooler. The temperature may fluctuate during the year, but in some equatorial forests the average may vary as little as 0.5F (0.3C) throughout the year. Temperatures are generally moderated by cloud cover and high humidity.

Answer 2

The amount of rainfall a forest receives each year can vary widely depending on its location and climate. Tropical rainforests typically receive over 100 inches of rain annually, while temperate forests may receive between 30-70 inches of rainfall per year. Desert forests may receive very little rainfall, while coastal forests may experience higher amounts due to proximity to water bodies.
