metamorphic rock
Yes sedimentary rocks form from erosion, consolidation, and cementation of old rocks. Metamorphic rocks form from changes to an existing rock through a mineralogical change within brought on primarily by heat and to some extent by pressure.
Yes, a metamorphic rocks is an existing rock that has been transformed via heat and pressure.
Clastic rocks are made from fragments of pre-existing rocks.
From the actions of heat and presure on pre-existing rocks.
Metamorphic rocks can form from the transformation of pre-existing rocks under high temperatures and pressures. Common parent rocks include shale, limestone, and granite. The minerals present in the parent rocks determine the types of metamorphic rocks that can form.
These rocks are metamorphic rocks. They form when existing rocks (igneous, sedimentary, or other metamorphic rocks) undergo high temperatures and pressure deep within the Earth's crust, causing their minerals to recrystallize and new minerals to form. Metamorphic rocks can have distinct textures and structures depending on the intensity of the heat and pressure they experienced.
Igneous, metamorphic, and existing sedimentary rocks can weather and erode to form sedimentary rocks. Igneous and metamorphic rocks can break down into sediments through processes like weathering and erosion, which then may accumulate and lithify into sedimentary rocks. Existing sedimentary rocks can also be reworked and lithified to form new sedimentary rocks through processes like compaction and cementation.
Clastic and chemical rocks are both types of sedimentary rocks. They form from the accumulation and cementation of sediment particles. Clastic rocks are composed of fragments of pre-existing rocks, while chemical rocks form from the precipitation of minerals from water solutions.
Metamorphic rocks.
Deposited weathered rocks can form sedimentary rocks through processes like compaction and cementation. These rocks are made up of fragments of pre-existing rocks that have undergone weathering and erosion before ultimately being deposited and lithified to form a new rock.
Clastic sedimentary rocks form from the breakdown and erosion of larger rocks, through processes like weathering, transportation, and deposition. These sediments are then compacted and cemented together to form rocks like sandstone, shale, and conglomerates.
Metamorphic rocks are formed from an existing rock (of any of the three types) being subjected to a combination of heat and pressure.
