How are different types of rock impacted by weathering?

rocks of soft nature get weathered easily like igneous rocks for example all volcanic rocks. rocks like metamorphic rocks do not get weathered easily as they are formed after tremendous procession of heat .example marble

Different types of rock are impacted by weathering in various ways depending on their composition and characteristics. However, weathering generally affects rocks through mechanical weathering and chemical weathering processes. Mechanical weathering involves the physical breakdown of rocks into smaller fragments, while chemical weathering involves the alteration of rock minerals through chemical reactions.

For example:

1. Igneous rocks, such as granite, can be weathered through both mechanical processes like frost wedging and chemical processes like hydrolysis, leading to the breakdown of minerals like feldspar and the formation of clay minerals.
2. Sedimentary rocks, like sandstone, can undergo mechanical weathering through processes like abrasion by wind and water, as well as chemical weathering through dissolution of minerals like calcite.
3. Metamorphic rocks, such as marble, can be impacted by mechanical weathering through exfoliation and chemical weathering through reactions with acidic rainwater, leading to the dissolution of minerals like calcite.

Overall, the specific impacts of weathering on different types of rock depend on factors such as mineral composition, porosity, and environmental conditions.
