Both the temperate grasslands and temperate forests experience <u>seasonal climatic changes </u>
Explanation:
Both the temperate grasslands and temperate forests experience experience all the four seasons - spring, summer, winter and fall.
These climatic changes can be observed throughout the year with summer being warm and dry and winter being very cold. The summer temperature averages around 21 degrees centigrade while the winter temperature can go down below freezing levels.
This extremely cold winter leads to shedding of leaves of deciduous trees found in the temperate forests. The grasses in the temperate grasslands also shed and die annually with the roots and new buds protected by the soil during the cold weather.
