Movement and sensing

Mechanical weathering

Breaking down rocks into smaller peones without changing their chemical composition

Example of mechanical weathering

Rocks grind against each other by wave action, wind, or glacial movement.

Chemical weathering

Breakdown of rocks through chemical reactions that changes their mineral composition

Chemical weather example

Oxygen interacting with metals and leading to rust

Biological weathering

The breakdown of rocks by living organisms, either mechanically or chemically

Biological weathering example

Plant roots grow into cracks and force rocks apart
