GEOLOGY

Detailed explanation-1: -Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock. The parent rock can be either sedimentary, igneous, or even another metamorphic rock.

Detailed explanation-2: -The parent materials for all rocks (including sedimentary, igneous, and metamorphic rock) is magma. Magma refers to molten (liquefied by extreme heat) or partially molten rock that is found underneath the Earth’s crust.

Detailed explanation-3: -The parent rock is also called the bedrock. Soil is formed from the parent rock.

Detailed explanation-4: -Common metamorphic rocks include phyllite, schist, gneiss, quartzite and marble. Foliated Metamorphic Rocks: Some kinds of metamorphic rocks–granite gneiss and biotite schist are two examples–are strongly banded or foliated.
