The earth’s crust is made up of various types of rocks. Any natural mass of mineral matter that makes up the earth’s crust is called a rock. Rocks can be of different colours, sizes, and textures.
There are three major types of rocks: Igneous Rocks, Sedimentary Rocks, and Metamorphic Rocks.
The uppermost layer over the earth’s surface is called the crust
Fossils: The remains of dead plants and animals trapped in the layers of rocks are called fossils.
