I love one direction ♥
Sedimentary rocks can be both chemically and mechanically weathered.
When sedimentary rocks are physically changed, their size and shape may be altered through processes like weathering and erosion. When they are chemically changed, minerals within the rocks may be dissolved or precipitated, leading to the formation of new minerals and the alteration of the rock's composition. Both physical and chemical changes can result in the transformation of sedimentary rocks into new rock types through processes like metamorphism.
Chemically formed sedimentary rocks are formed from dissolved minerals that precipitate out of water through processes like evaporation or chemical reactions. Examples include rocks like limestone, rock salt, and gypsum.
Sedimentary rocks are by definition composed of little pieces of eroded rocks. So, yes!
no
It can be changed by being broken down in the weathering process just like all rocks. The resulting sediment can then be lithified to for a sedimentary rock.
sedimentary rocks can be changed into metamorphic rocks by the use of pressure and/or heat
Metamorphic rocks originate as igneous and sedimentary rocks, but have been changed by heat and pressure.
Biologically, Chemically and Mechanically.
1. Organically. 2. Mechanically. and 3. Chemically.
Sedimentary rocks can be changed into metamorphic rocks through heat and pressure, while igneous rocks can be changed into metamorphic rocks through the same process. Both types of rocks can also be weathered and eroded, leading to the formation of new sedimentary rocks.
Sedimentary,and Igneous.Metamorphic can change to either one of those.
