Metamorphic Rocks
A rock that is subjected to heat and pressure. They may be formed simply by being deep
beneath the Earth's surface. Being formed they are subjected to high
temperatures and the great pressure of the rock layers above it.
Some examples of metamorphic rocks are gneiss, slate, marble, schist, and quartzite.
There also are two types, Foliated and Non foliated.

Non foliated Metamorphic do not have a layered or banded appearance

Igneous
forms when magma (molten rock) cools and solidifies. The solidification process may or may not involve crystallization, and it may take place either below the Earth's surface to generate "intrusive" rocks or on the surface to produce "extrusive" rocks.

Intrusive Igneous
Intrusive rocks are formed inside of the earth.
Examples include Granite.

Extrusive igneous
Extrusive rocks Are formed on the earth’s surface.
Examples include Pumice, Obsidian, and Basalt.

Sedimentary
These rocks are a type of rock that is formed by sedimentation of material at the Earths surface and within bodies of water.
Particles that form a sedimentary rock by accumulating are called sediment.
Before being deposited, sediment was formed by weathering and erosion in a source area.

How are rocks formed
Rocks are formed in several type of ways. For example metamorphic is formed by the
process of heat and pressure. Sedimentary Rocks are formed through the
process of weathering and erosion. Not last but least igneous rocks are formed
through Underground, they are formed when the melted rock, called magma, deep within the earth becomes trapped, they also are formed as the lava cools above ground.
