How does physical weathering compare to natural erosion?

Answer 1

Physical weathering and natural erosion are two different processes that contribute to the breakdown of rocks and minerals on the Earth's surface. Physical weathering involves the mechanical breakdown of rocks and minerals, while natural erosion involves the transport and removal of weathered materials by natural agents such as water, wind, and ice.

In physical weathering, rocks and minerals are broken down into smaller pieces through processes such as freezing and thawing, expansion and contraction due to temperature changes, and the actions of plant and animal life. Physical weathering does not involve the movement of the weathered materials and only affects the surface layers of the Earth's crust.

On the other hand, natural erosion involves the transportation of weathered materials away from their original location. This can occur through processes such as water erosion, where water carries away soil and sediment, or wind erosion, where winds blow away loose materials. Natural erosion can occur over large distances and can significantly alter the landscape.

In summary, physical weathering is a process that breaks down rocks and minerals through physical forces without causing much movement, while natural erosion involves the movement and transportation of materials away from their original location.
