This is magma in the volcano. Magma exists in the lower part of the crust and the upper part of the mantle. When magma cools it creates an intrusive or extrusive igneous rock.
When magma cooled it created me, a granite rock. I am also known as an intrusive igneous rock.
Deep in the crust, tectonic plates rub up against each other, which causes heat and pressure. All of this heat and pressure causes foliation. This then creates a metamorphic rock.
During that process I metamorphosed into a gneiss rock.
Since metamorphic rocks form very deep within the crust, it takes some kind of force to push the rocks up near the surface. This process is called folding. Folding is when a stack of sediments (normally flat) gets bent and curved due to heat and pressure.
This represents mass wasting. Mass wasting involves landslides and rock fall. It is a form of weathering.
