Because the sun's rays are directly overhead all year in the tropics, there are no identifiable seasons such as those in temperate zones. The tropical region has areas with dry and rainy periods, but time of year is not a factor. Instead, the amount of rainfall an area receives depends upon its distance from the equator. Areas closer to the equator receive more rainfall than areas farther away.
