There are more ways for weathering and erosion to happen:

Ice can make weathering happen
in cold places. Water gets into
empty spaces in the rock. When
water changes into ice, it gets

bigger. This pushes parts of the
rock away from each other and
breaks the rock. In some places

ice can also make erosion
happen. Moving ice can carry very
big rocks. This big rock was carried and left by moving ice.

Plants can make weathering
happen too. The roots

underground can grow in small
spaces in the rock. They grow and
push parts of the rock away from
each other, which breaks it.

Gravity can also make erosion

happen, by pulling rocks and soil
down. This can cause more
weathering too. This happens
when the falling rocks hit other
rocks and break them. Gravity

made the rocks in this picture fall.
