Answer The atoms in rocks rearrange to form denser minerals. The combination of heat and pressure may cause the minerals in the rock to separate into layers.

Answer Pressure squeezes out any remaining water that may be left in the metamorphic rock and minerals that have water as part of their structure are changed chemically to minerals that do not require water as part of their structure. The metamorphic rock will then have become a higher grade metamorphic rock possibly containing garnet, a non-hydrous mineral.

What causes sedimentary rocks to become metamorphic rocks?

Sedimentary rock can become metamorphic rock under intense heat and pressure. The heat and pressure do not change the rock's chemical composition, but do change its physical properties like hardness, texture, and structure.


What are rocks changed by intense pressure and heat become new rocks called?

Rocks changed by intense pressure and heat become new rocks called metamorphic rocks. These rocks form when existing rocks undergo changes in texture and mineral composition due to high temperatures and pressures. Examples of metamorphic rocks include marble, slate, and gneiss.


What rocks are formed from high temperature and pressures?

Rocks formed from high temperature and pressure include metamorphic rocks such as marble, schist, and gneiss. These rocks are created deep within the Earth's crust through the transformation of existing rock types under intense heat and pressure conditions.


High temperature and pressure cause igneous rocks to become what type of rock?

High temperature and pressure on igneous rocks cause them to transform into metamorphic rocks through a process called metamorphism. This process typically involves recrystallization of minerals and changes in texture and structure without melting.


How does pressure affect the formation and transformation of rocks?

Pressure plays a significant role in the formation and transformation of rocks. High pressure can cause rocks to change their structure and composition, leading to the formation of new types of rocks through processes like metamorphism. This pressure can come from the weight of overlying rocks or tectonic forces, and it can also affect the temperature at which rocks form. Overall, pressure is a key factor in shaping the Earth's crust and the rocks within it.

What is required to change an igneous rock into a sedimentary rock?

Igneous rocks are a "finished product". They do not become sedimentary rock - though sedimentary rocks, with heat and pressure can become metamorphic rocks.


What can happento a sedimentary rock once it is formed?

Sedimentary rocks can be eroded into sediments and form sedimentary rocks again, they can melt and become igneous rocks, and they can undergo extreme heat and pressure and become metamorphic rocks.


How does pressure help make metamorphic rocks?

What 2 things are applied to igneous or sedimentary rocks that make metamorphic rocks form?

Heat and pressure are applied to igneous or sedimentary rocks to make metamorphic rocks form. Heat causes mineral grains to recrystallize, while pressure helps to rearrange the mineral structure within the rock.
