Explain how igneous rock is formed and itβs main features
Igneous rocks are formed when magma or lava turns into a solid. They are hard and often contain crystals
Explain how sedimentary is formed and itβs main features
Sedimentary rocks are formed from the weathering of other rocks they are usually soft and sometimes contain fossils
Examples are sandstone and chalk
