The type of rock formed when great heat and pressure are applied to existing rock is called metamorphic rock. This process, known as metamorphism, alters the mineral composition and texture of the original rock, which can be either igneous, sedimentary, or even another metamorphic rock. Common examples of metamorphic rocks include schist, gneiss, and marble. These rocks often exhibit distinct foliation or banding due to the directional pressure applied during their formation.

Which rocks are formed by the alteration of pre-exi sting rocks by great heat or pressure?
Metamorphic rocks are formed by the alteration of pre-existing rocks through great heat and pressure. This process changes the mineral composition and texture of the original rocks, resulting in the formation of new minerals and textures. Examples of metamorphic rocks include marble, slate, and schist.
Can an exsiting rock change into another type of rock only when it it is subjected to great pressure?
Yes, existing rocks can undergo a process called metamorphism which involves being subjected to great pressure, along with changes in temperature and chemistry. This can lead to the formation of new types of rocks, such as marble from limestone or schist from shale.
Are the diamonds formed the same way as igneous rocks?
No. Igneous rock is formed from the solidification of magma or lava. Diamond is a mineral which is formed at great depth below the surface, from intense pressure and heat.
How are metophic rocks formed?
Heat and pressure can change many things. They can even change rocks. The name for rocks that has been changed is metamorphic (met uh MOR fik) rocks. Metamorphic comes from Greek words meaning "change" and "form". Metamorphic rock is the result of the transformation of an existing rock type, the protolith, in a process called metamorphism, which means "change in form". The protolith is subjected to heat and pressure (temperatures greater than 150 to 200 °C and pressures of 1500 bars[1]) causing profound physical and/or chemical change. The protolith may be sedimentary rock, igneous rock or another older metamorphic rock. Metamorphic rocks make up a large part of the Earth's crust and are classified by texture and by chemical and mineral assemblage (metamorphic facies). They may be formed simply by being deep beneath the Earth's surface, subjected to high temperatures and the great pressure of the rock layers above it. They can be formed by tectonic processes such as continental collisions which cause horizontal pressure, friction and distortion. They are also formed when rock is heated up by the intrusion of hot molten rock called magma from the Earth's interior.
Describe what happens to rock during pressure release?
Rock deep within the Earth is under great pressure from the rocks around it. As the rock above it is weathered and eroded, it moves closer to the surface, and the pressure from above is lessened. What happens to the uplifting rock that was once under great pressure depends on the rock type, but can vary from simple exfoliation of its surface to widespread cracking and faulting of the rock body from the release of pressure.
Which rocks are formed by the alteration of pre-existing rocks by great heat or pressure?
Metamorphic rocks are formed by the alteration of pre-existing rocks due to high heat and pressure deep within the Earth's crust. Examples of metamorphic rocks include marble, slate, and schist.
What is a rock formed when high heat and great pressure change existing rocks?
A metamorphic rock is formed when existing rocks are subjected to high heat and pressure, causing their mineral composition and texture to change. This process occurs deep within the Earth's crust or during tectonic plate movements.
What is it called when a rock changes?
Metamorphism....A metamorphic rock is a rock formed when it undergoes chemical reactions,tremendous heat and great pressure to form a new kind of rock from an existing one.
What is a rock that is formed with great heat and great pressure?
It is called a metamorphic rock.
How marble stone formed?
Marble is formed when limestone is subjected to pressure and great heat.

How was serpentine formed?
Serpentine is a metamorphic mineral, so it was formed by high heat and great pressure, most often from peridotite.

What type of rock is formed when other rocks are exposed to great heat and pressure?
Metamorphic.
Gneiss is formed from what rock?
Gneiss is a metamorphic rock. It is formed form another metamorphic rock called schist (sh-ist). Schist is formed form fine grained sedimentary rock (often shale). While gneiss is formed by great pressure from moving plates of the earth's crust.
Are the diamonds formed the same way as igneous rocks?
No. Igneous rock is formed from the solidification of magma or lava. Diamond is a mineral which is formed at great depth below the surface, from intense pressure and heat.
