How can frozen water induce rock weathering
Web19 de fev. de 2024 · Foothill College. Weathering is the process by which surface and subsurface rocks disintegrate, dissolve, or are broken down. Rocks at or near the earth's surface are exposed to physical and chemical weathering processes. Weathering is known as an exogenic process because it (like all exogenic systems) is powered by insolation, … WebCHAPTER 6 (Weathering and Soil) 1. Weathering is a term which describes the general process by which rocks are broken down at the Earth’s surface into such things as sediments, clays, soils and substances that are dissolved in water. 2. The process of weathering typically begins when the earth’s crust is uplifted by tectonic forces.
