Rock cycle shows the changes in the three kinds of rocks over time.
The rock cycle refers to the description of the geological processes that rocks go through to become igneous, sedimentary and metamorphic.
The cycle shows the time it takes for the different types of rocks to form and how this change is related to the water cycle and the way the tectonic plates move.
Igneous rocks can form when magma penetrates through cracks in existing rocks or by cooling lava from volcanic eruptions.
Sedimentary rocks are formed by the consolidation of sediments that come from erosion.
That is, igneous rocks undergo different processes such as erosion, transport and weathering, which causes the rock to transform into small particles (sediments).
Over time, they are transformed due to the weight of the successive layers deposited and the action of water, forming rocks by a process called lithification.
The metamorphic rocks suppose the alteration in solid state of rocks that are already consolidated in the earth's crust.
That is, sedimentary rocks are affected by the movement of the earth's crust related to the movement of tectonic plates and the formation of mountains.
Therefore, we can conclude that rock cycle shows the changes in the three kinds of rocks over time.
