Metamorphic rock, such as schist or gneiss, can be formed when volcanic rock is altered by heat and pressure. This process can cause the mineral composition and texture of the rock to change, resulting in a new type of rock with different features than the original volcanic rock.
Altered varieties of granite formed during the cooling period include gneiss, schist, and migmatite. These rocks are created when the original granite undergoes intense heat and pressure, causing recrystallization and alteration of the minerals in the rock.

Rocks can also be classified based on their mineral composition and how they were formed. The three major rock types are igneous (formed from cooling and solidification of magma), sedimentary (formed from accumulation and compaction of sediments), and metamorphic (formed from existing rocks that were altered by heat and pressure).
Sedimentary rocks are formed by a four step process called Lithification (1. Erosion, 2. Deposition, 3. Cementation, 4. Compaction). Metamorphic rocks are formed by heat, time, and pressure.
Rock formed by heat and pressure becomes transformed and altered, such rock is called Metamorphic Rock.
Metamorphic rock is altered by heat and pressure.
Metamorphic rock
No. Volcanic rock (or igneous rock) is formed when lava cools. A metamorphic rock is formed when a rock changes because of tremendous heat and pressure underneath the earth to become a new type of rock.
No. Coal is the result of organic material, primarily plant matter from bogs, being chemically altered by heat and pressure, leaving being mostly carbon.
Slate is formed by heat and pressure on shale or mud stone. It splits into perfectly cleaved, broad thin sheets. It is a sedimentary rock made of volcanic ash.

Marble is a metamorphic rock so it was formed by heat and pressure. :)
formed by immense heat and pressure
Altered varieties of granite formed during the cooling period include gneiss, schist, and migmatite. These rocks are created when the original granite undergoes intense heat and pressure, causing recrystallization and alteration of the minerals in the rock.
the metamorphic rocks are formed by heat and extreme pressure from other rocks
When the heat of earth boosts the heat need to come out. After that heat makes pressure and volcano erupts.
