Refer to the diagram. Name the geomorphic process and explain it.

Here is the solution to your assignment:

Question 3: Refers to the diagram below.

• I. Name the geomorphic process? The geomorphic process is weathering. More specifically, it is biological weathering or root wedging.
• II. Refer to the answer above, briefly explain this process in your own understanding? Biological weathering occurs when plant roots grow into cracks in rocks. As the roots grow larger and thicker, they exert pressure on the rock, causing the cracks to widen and eventually break the rock apart.

Question 3: Refer to the following diagram.

• I. What type of weathering depicts the image? The type of weathering depicted is freeze-thaw weathering (also known as frost wedging).
• II. Explain in your own understanding how these process occurs from A to C? Freeze-thaw weathering occurs when water enters cracks in rocks (A). When the temperature drops below freezing, the water turns into ice and expands (B). This expansion exerts pressure on the surrounding rock, causing the cracks to widen. Over many cycles of freezing and thawing, the repeated pressure eventually causes pieces of the rock to break off (C).
