I think the temperate deciduous forests are located in the mid-latitude, which means they are found between the polar regions and the tropics. The deciduous forest regions are exposed to warm and cold air masses. It cause this area to have four seasons. The temperature varies widely from season to season with cold winters and hot, wet summers. The average yearly temperature is about 10 degrees. The areas in which deciduous forests are located get about 750 to 1500 mm of precipitation spread fairly evenly throughout the year.
