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.


Rocks are classified as igneous sedimentary or metamorphic based primarily on their?

Rocks are classified as igneous, sedimentary, or metamorphic based primarily on their origin and how they were formed. Igneous rocks are formed from cooled magma or lava, sedimentary rocks are formed from the accumulation of sediments, and metamorphic rocks are formed from the alteration of existing rocks due to heat and 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 makes the 3 types of rocks different?

The three types of rocks - igneous, sedimentary, and metamorphic - are different in terms of how they are formed. Igneous rocks are formed from the cooling and solidification of molten material, sedimentary rocks are formed from the accumulation and cementation of mineral and organic particles, while metamorphic rocks are formed from the alteration of existing rocks due to heat and pressure within the Earth's crust.


What m described rocks that were formed when existing rocks were heated or squashed?

Metamorphic rock. This can naturally form an existing Sedimentary, Igneous or Metamorphic rock due to exposure to heat and/or pressure.

What is metamoprphic rock formed from?

Metamorphic rocks are formed when the minerals in a rock are change chemically. Normally these rocks are near magma and get heated up, but do not melt.


When rocks are metamorphosed the pressure causes them to become what?

Deformed, and change into metamorphic rocks.


Are metamorphic rocks naturally formed?

Are metamorphic rocks only formed by igneous rocks?

No. Metamorphic rocks can also from front sedimentary rocks and from other metamorphic rocks.


What rocks are formed by the effect of heat and pressure on other rocks?

the metamorphic rocks are formed by heat and extreme pressure from other rocks


Metamorphic rocks can only be formed from?

Metamorphic rocks can be formed from any pre-existing rock type (igneous, sedimentary, or other metamorphic rocks) that undergoes intense heat, pressure, or chemical changes without melting. This process causes the minerals in the rock to recrystallize and reorganize, resulting in a new metamorphic rock with different properties.


What is the term when rocks are formed when older rocks are heated or squeezed?

If it is squeezed and heated sufficiently to realign the minerals or form new minerals, it is called a metamorphic rock. If it is squeezed and heated enough to melt, then solidify, it would be called an igneous rock.


Rocks that are created when existing rocks are heated or squeezed?
