Explanation:
Metamorphic means change in form
metamorphic rocks are formed when existing rocks undergo changes
-sedimentary and igneous rocks can change into metamorphic rocks, and metamorphic rock can change into different metamorphic rocks.
-During the process of metamorphism, rocks and minerals change in response to temperature, pressure, or other environmental changes.
Type of metamorphic rocks are slate, phyllite, Gneiss.
A metamorphic rock is a changed rock. It is formed when sedimentary or igneous rocks are exposed to high temperatures and or pressures.
Explanation:
The heat of a volcano can affect the nearby rocks that are exposed to the high heat of the magma, transforming them into metamorphic rocks.
When sedimentary rocks are push/pulled down deeper into the crust at a subduction zone the rocks are subjected to high pressures the pressure can compact the sedimentary rocks turning them into metamorphic rocks. Limestone is hardened into marble.
Meta means change. This helps to remember that metamorphic rocks are changed rocks.
