1.     Igneous Rock

Igneous rock is formed through the cooling and solidification of magma or lava. Igneous rock may form either below the surface as intrusive rocks or on the surface as extrusive rocks. Typically, the melting is caused by an increase in temperature, a decrease in pressure, or a change in composition.

2.      Sedimentary Rock

Sedimentary rock is formed by sedimentation of material with weathering and erosion by water, wind, mass movement or glaciers. Sedimentary rocks are deposited in layers as strate, forming a structure called bedding. Sedimentary rocks are also important sources of natural resources like coal, fossil fuels, or ores.

3.     3. Metamorphic Rock

Metamorphic rock is formed from other sedimentary or igneous rocks. Metamorphism takes place at depths within the Earth's crust, where both temperature and pressure are higher than at the surface. These two factors, heat and pressure, cause physical or chemical change.
