II. Directions: For each of the situations below, state whether it describes erosion, weathering, or possibly both. Explanation Erosion, Weathering or Both Activity 1. A very large storm occurs along the coast. The powerful waves wash away sand and move some larger rocks on the shore. 2. Rainfall collects in a crack in a rock. When the temperature drops, this water freezes and expands. This causes the crack to become slightly larger. 3. This rock is at the top of a cliff. After several years, the crack is large enough that a piece breaks off and tumbles to the bottom.

I1. Directions: For each of the situations below, state whether it describes erosion, weathering, or possibly both.
Explanation
Erosion,
Weathering
Activity
or Both
1. A very large storm occurs along the coast. The
powerful waves wash away sand and move some
larger rocks on the shore.
2. Rainfall collects in a crack in a rock. When the
temperature drops, this water freezes and expands.
This causes the crack to become slightly larger.
3. This rock is at the top of a cliff. After several years,
the crack is large enough that a piece breaks off and
tumbles to the bottom.
4. A tree in your front yard spreads its roots beneath a
sidewalk, pushing the sidewalk up and causing it to
crack. As the tree grows, these cracks are expanded
as the roots grow into and between them.
5. A glacier scrapes pieces of rock from underneath it
and carries these pieces down the side of a
mountain and into the valley.
6. A river flowing through soft rock dissolves some of
the rock and carries this material downstream.
7. As a fire rages through a forest, a large boulder is
heated quickly. This rapid change in temperature
causes the outer layer of the boulder to crack.
8. The expansion of ice on a cold night breaking up a
road surface.
9. River flowing through fields as it changes its
course.
10. A gully formed by running water, eroding sharply
into soil.
