Activities take a ten question quiz about this page. The rocks in the earth s crust continuously undergo changes in their composition which leads to formation of other rocks. Rocks melt deep beneath earth s surface. Rocks beneath earth s surface are forced toward the mantle.

Each rock has a unique formation process. These conditions often stretch twist and fold the rock as it cools. Types of metamorphic rocks include gneiss quartzite marble schist soapstone and phyllite. Layers of sedimentary rocks are called strata.

Metamorphic rocks arise from the transformation of existing rock types in a process called metamorphism which means change in form.

As per wikipedia metamorphic rocks arise from the transformation of existing rock types in a process called metamorphism which means change in form the original rock protolith is subjected to heat temperatures greater than 150 to 200 c and pressure 1500 bars causing profound physical and or chemical change. During the formation of metamorphic rocks what most likely causes pressure to increase. Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met.

The original rock is subjected to heat temperatures greater than 150 to 200 c and pressure 100 megapascals 1 000 bar or more causing profound physical or chemical change the protolith may be a sedimentary igneous or existing 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. It is formed by the metamorphism of limestone. Gravity pulls on rocks.
