Question

What is weathering and erosion

Answer 1

Once the rock has been weakened and broken up by weathering it is ready for erosion. Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity. Mechanical weathering physically breaks up rock. One example is called frost action or frost shattering.

Answer 2

Weathering is when rocks, soil, or other minerals are broken down.

Erosion is the process through which weathered rock is moved from one place to another. Erosion can dissolve rock by weakening the rock or by turning it into other fragments that are very small.
