Review Erosion-2

Are the ocean waves crashing against this rock an example of:

  1. Erosion

    Partially right! This is an example of erosion. Sand and bits of the rock are being moved by the waves..
  2. Weathering

    Partially right! This is an example of weathering too. Weathering is when a rock is broken into smaller pieces. The waves and the sand they carry are slowly grinding away these rocks.

  3. Both erosion and weathering

    Yes! The rock is being broken into smaller pieces by the waves (weathering), and the pieces are also being carried away by the waves (erosion).
  4. Neither erosion nor weathering

    No. Both weathering and erosion are happening here.

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.
