The provided diagram illustrates the main stages in the creation and destruction of rocks in the cycle.
Overall, the rocks are made and destroyed in a complex cycle which includes four stages, beginning with sediment sinks into the ground and finishing with rocks erode from mountains.
Firstly, the sediment on the seabed gradually sinks into deeper layers of the ground, creating sedimentary rock. The following stage is the transformation of sedimentary rock into metamorphic rock with the help of high pressure and temperature in deep layers of the Earth. When metamorphic rock reaches a high enough temperature, it liquefies and follow the flow of magma into volcanoes.
Once the magma cools, it becomes Igneous rock which is a type of volcanic stone. In addition, it is evident that lava erupted from volcanoes when being cooled in a short amount of time also transforms into this kind of rock. Subsequently, three kinds of aforementioned rocks including sedimentary rock, metamorphic rock and igneous rock all rises in a slow pace to the ground, then are moved by rain and causes erosions and starts the cycle again.
