Erosion
refers to when soil is removed from the land. During big storms,
large waves may form on lakes and ponds. When these waves
crash into the shore, big chunks of soil are sometimes swept back
into the lake or pond. This can be bad for houses near the
shoreline because the ground that supports these homes is slowly
being taken away. Do you think having a wetland between the
house and the shore would help prevent such erosion?
Erosion is also caused by water running down a steep hill.
As the water runs down the hill, it may take large amounts of soil
and sediment with it. If there is a water body, like a stream,
at the bottom of the hill, then the soil and sediment carried by
the water can cloud the stream. When the stream is clouded
from too much soil and sediment, plants that live in the water of
the stream may not get enough sunlight to grow, or fish that require
clear water may not lay their eggs. Do you think less soil
and sediment would reach the stream if there was a wetland between
the top of the hill and the water body?
