Question

1. this picture of a pothole relates to what kind of physical erosion, explain how?

Explanation:

Potholes are often formed due to water - related physical erosion. Water seeps into cracks in the pavement. When it freezes, it expands, causing the cracks to widen. Then, traffic load breaks up the weakened pavement material, and water flow can carry away the loose debris. This is a form of mechanical or physical erosion related to the action of water and mechanical forces from traffic.

Answer:

Water - related physical erosion. Water infiltration, freezing - thawing cycles, and traffic forces contribute to the formation.
