How does metamorphic rock become sediment?
At the surface, metamorphic rocks will be exposed to weathering processes and may break down into sediment. These sediments could then be compressed to form sedimentary rocks, which would start the entire cycle anew. rock formed by the cooling of magma or lava.
What converts rocks into sediment?
Weathering and erosion. Water, wind, ice, and even plants and animals all act to wear down rocks. Over time they can break larger rocks into sediments. Rocks break down by the process called weathering.
What process forms sediment?
Erosion and weathering transform boulders and even mountains into sediments, such as sand or mud. Dissolution is a form of weathering—chemical weathering. With this process, water that is slightly acidic slowly wears away stone. These three processes create the raw materials for new, sedimentary rocks.
How are sediments formed?
Sediment transport and deposition This sediment is often formed when weathering and erosion break down a rock into loose material in a source area. The material is then transported from the source area to the deposition area.
What process forms metamorphic rocks?
Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.
What is metamorphism process?
Metamorphism is a process that changes preexisting rocks into new forms because of increases in temperature, pressure, and chemically active fluids. Metamorphism may affect igneous, sedimentary, or other metamorphic rocks.

How are sedimentary rocks formed in the rock cycle?
Sedimentary – A rock formed as a result of the weathering process, either by compaction and cementation of rock mineral fragments, or the precipitation of dissolved minerals. Metamorphic – These rocks form as existing rocks are subjected to intense heat and/or pressure, usually over long periods of time.
How are metamorphic rocks changed?
Metamorphic rocks form when sedimentary, igneous, or pre-existing metamorphic rocks are changed by heat, pressure, and chemically reactive waters. These rocks are identified by their minerals and texture.
How can a rock change during metamorphism?
Metamorphism occurs because some minerals are stable only under certain conditions of pressure and temperature. When pressure and temperature change, chemical reactions occur to cause the minerals in the rock to change to an assemblage that is stable at the new pressure and temperature conditions.
What is the process of metamorphic rocks?
Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
What is the rock cycle of a metamorphic rock?
Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
What forces cause sedimentary rock to metamorphic rock?
When Sedimentary rocks are buried deep beneath the Earth's surface, great pressure and tremendous heat change these rocks into new rocks containing different minerals. These are Metamorphic rocks.
How does a metamorphic rock change into another type of rock?
Metamorphic rocks are formed by tremendous heat, great pressure, and chemical reactions. To change it into another type of metamorphic rock you have to reheat it and bury it deeper again beneath the Earth's surface.
What process transforms a metamorphic rock into an igneous rock?
Furthermore, metamorphic and sedimentary rocks thrust deep underground through subduction may eventually melt to form magma and cool into igneous rock once again. The entire process is called the rock cycle. The rock cycle takes many millions of years to complete, but it is the key to geologic change on our planet.
