My Rock Writing

Rocks
There are three basic types of rock: Igneous, Sedimentary, and Metamorphic. In this writing you are going to find more about the three types of rocks.

Intrusive Igneous rocks crystallize beneath the earth, and the slow cooling that occurs there allows large crystals to form. Extrusion igneous rocks erupt onto the surface, where they cool quickly to form small crystals. Some cool so quickly that they form an amorphous glass.

There are three basic types of Sedimentary rocks but I'm going to tell you about coal, coal is an organic Sedimentary rock that forms from plant debris. Plant debris is a type of food waste that forms from dead branches, leafs etc.

The last rock i’m going to tell you about is Metamorphic rocks, Metamorphic rocks have been modified by heat, pressure, and chemical processes, usually while buried deep below Earth's surface. Exposure to these extreme conditions has altered the mineralogy, texture, and chemical composition of the rocks.
