WebRocks are constantly being recycled and going through several processes of chemical and physical changes. There are three main rock types: Sedimentary Metamorphic Igneous The diagram below shows that rocks … WebWhen sediment builds up over time and hardens over years, now you have a sedimentary rock. Slowly this sedimentary rock gets covered with other rocks and ends up deep in the Earth’s crust. When the pressure and heat get high enough, the sedimentary rock will change into a metamorphic rock and the cycle starts all over again. dbeaver client download
