How does weathering affect granite
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 ... WebMay 19, 2024 · How does the weathering of granite affect the rock? The fissures expand to larger fractures as the rock cools further. Wind, water and ice denude the soil and Earth’s crust overlying the granite mass, exposing it to the atmosphere. The rock expands and contracts in reaction to changes in temperature.
