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.
Igneous rocks are formed from the cooling of magma from deep in the earth. magma is the heart of any igneous rock.when maaagme cools it turns into Igneous rocks.

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.
