AI overview
Weathering is the process by which rocks break down and wear away over time due to exposure to natural forces like wind, water, and temperature changes. It matters because it shapes landscapes, creates features like natural arches, and contributes to the formation of soil that supports life.

Weathering is the deterioration of rocks, soils and minerals (as well as wood and artificial materials) through contact with water, atmospheric gases, sunlight, and biological organisms. It occurs in situ (on-site, with little or no movement), and so is distinct from erosion, which involves the transport of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity.
