Rock Your Knowledge

Erosion and Weathering

• Erosion involves the movement of rocks and sediment that have been broken apart due to various forces such as water, wind, and ice.
• Weathering is the process of decomposing, breaking apart, or changing the color of rocks, influencing the rock's physical and chemical properties.

Physical and Chemical Changes

• Breaking up a rock into smaller pieces is part of mechanical weathering, which involves physical processes that reduce rocks to smaller fragments without altering their chemical composition.

Coastal Erosion

• When salty sea water crashes against coastlines, it causes erosion, which reshapes the landscape by wearing away rocks and transporting sediments along the shore.

Sediment Transport

• The movement of rocks and sediment from one location to another is a crucial aspect of both erosion and sediment transport, allowing geological material to be redistributed across different environments.
