How do rates of erosion vary with geology
WebErosion is a mechanical process, usually driven by water, wind, gravity, or ice, which transports sediment and soil from the place of weathering. Liquid water is the main agent … WebApr 8, 2024 · Although mineral weathering is sometimes limited by dissolution kinetics, other factors play an important role as well. For example, physical erosion can affect silicate weathering rates by modulating the supply of fresh reactive minerals (e.g., Stallard and Edmond, 1983; Calmels et al., 2007 ). Additionally, precipitation (and in turn runoff ...

WebThe processes are very complicated because of the feedbacks. Answer 2: Mountains can change in several ways over time. They can undergo erosion by rain and wind, as well as landslides due to flooding. Some mountains change via volcanic activity. They may also change due to earthquakes and shifting of tectonic plates.
