Chemical change causes transformation of sedimentary rocks into metamorphic rocks due to high temperature and pressure.
Explanation:
If the rocks are situated deep into the earth then due to pressure and tremendous temperature of earth causes metamorphosis.The hot magma surrounds the rock and changes the shape of the rock.
Changing temperature and pressure creates unstability of the mineral constituents of the rock which is a major factor for changing the sedimentary or igneous rocks into metamorphic rocks.
Earthquakes are caused by the movement along the fault, which is found near the boundaries of two tectonic plates. The specific fault where plates slide against each other is known as the transform fault.
