WebThey are formed when very tiny particles like minerals, plants, bones ( also called sediment) get deposited in one place over a long period of time. After many years of deposition these particles get compressed into large chunks of rocks that we call sedimentary rocks. Three fourth of world’s land is made up of sedimentary rocks. WebIgneous rocks are formed when melted rock cools and solidifies. Melted rock may come in the form of magma, when it is found underneath the Earth’s surface. It can also come in the form of lava, when it is released unto the Earth’s surface during a volcanic eruption. Some examples of igneous rocks are granite, scoria, pumice, and obsidian. WebThree Types of Rock. Rocks fall into these three groups: Igneous , Sedimentary , and Metamorphic. Igneous rocks are formed from melted rock deep inside the Earth.
