Three main types of rocks

Rocks are classified into three main types based on their formation processes. Igneous rocks originate from the cooling of magma deep within the Earth's crust. These rocks can take various forms, such as basalt and gabbro, depending on the conditions under which the magma cools.

sedimentary

coal

turbidite

sedimentary rocks are formed through solidification of sediment.sedimentary rocks were named that because they were once sediment.

Metamorphic

metamorphic rocks are formed through the change [metamorphosis] of igneous and sedimentary rocks. A contact metemorphism is rocks are so close to magma that they partially melt and change so much that they change there properties.
