How are metophic rocks formed?

Answer 1

Quick Answer: temperature and/or pressure applied to any type of rock (sedimentary, igneous, and even metamorphic) can cause said rock to become metamorphosed. For example, marble is the metamorphosed equivalent of a carbonate rock.

Answer 2

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.

Answer 3

Metamorphic rocks takes from as much as thousands of years to just a few minutes to form depending on the type of metamorphism involved and the range of existing physical properties like temperature and pressure involved.

Answer 4

Metamorphic rock is formed when Igneous rock and Sedimentary rock go through intense heat and pressure.

Answer 5

A change through the action of heat and pressure
