Review Erosion-6

This tree is growing in a crack in this layer of rock. As it grows, it will break the rock apart, and its roots will force their way into smaller cracks, pushing them apart too. This is an example of:

  1. Erosion

    No. Erosion means that the pieces of rocks are being carried away. The pieces of rock are not being removed.
  2. Weathering

    Yes! The roots of the tree are breaking the layer of rock into smaller pieces. As it continues to grow, its roots will break the rock into smaller and smaller pieces. The process of breaking rocks into smaller pieces is called weathering, even when it is not actually done by the weather.

  3. Both erosion and weathering

    No. The rock is not being moved, so it is not erosion.
  4. Neither erosion nor weathering

    No. The tree is breaking the large rock into smaller rocks, which is an example of weathering.

Utah


UT.4.III.2.b Distinguish between weathering (i.e., wearing down and breaking of rock surfaces) and erosion (i.e., the movement of materials).

UT.5.II.1.a Identify the objects, processes, or forces that weather and erode Earth’s surface (e.g., ice, plants, animals, abrasion, gravity, water, wind)

UT.8.III.2.b Describe the role of energy in the processes that change rock materials over time.
