GEOLOGY

Detailed explanation-1: -Physical weathering Wind can cause weathering by blowing grains of sand against a rock, while rain and waves cause weathering by slowly wearing rock away over long periods of time.

Detailed explanation-2: -Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. A similar process, weathering, breaks down or dissolves rock, but does not involve movement.

Detailed explanation-3: -Rocks are continually weathered down by wind, water, chemicals, and ice. After the rocks are broken down into smaller pieces we call sediment, they are eroded away and deposited in lake beds and on the ocean floor. Wind erosion is the process by which wind moves sand or soil from one location to another.

Detailed explanation-4: -Abrasion is driven by water, wind, ice, or gravity. A strong wind, for example, can blow sediments against rock surfaces, wearing down the rock. Abrasion can make angular rocks smooth and rounded.
