- 1. Erosion and weathering are important geological processes that shape the Earth's surface over long periods of time. Weathering refers to the breakdown of rocks and minerals on the Earth's surface by various physical, chemical, or biological processes. This can include processes such as frost wedging, chemical reactions, and root growth. Erosion, on the other hand, involves the transport of weathered material by natural forces such as wind, water, or ice. Together, weathering and erosion work to slowly but continually reshape the landforms that we see today, creating canyons, valleys, and other geological features.
