Explain when each of the following process occur in the rock cycle- Compaction and Cementation, Melting; Cooling and hardening, Heat, pressure, weathering and Erosion.

The rock cycle shows how the earth's rocks are changed again and again. The rocks can be changed at times to another type of rock. The rock cycle can begin anywhere in the cycle. Here’s how it works…

• Igneous rocks start as magma. Technically, ALL rocks start as magma.

• The magma (molten rock under the surface) and lava (molten rock on the surface) hardens into igneous rock.

• The igneous rock then breaks apart over time through the process of weathering.

• These bits of broken rock are washed away by rains and deposited in a river.

• These pieces of igneous rocks are cemented together with other bits of rock and form a sedimentary rock called conglomerate.

• Over time sedimentary rocks can be buried by earthquakes or other geologic processes.

• Being buried deep under the surface in areas of high temperatures and pressures or coming in contact with magma can cause these sedimentary rocks to change to metamorphic rocks.

• Metamorphic, sedimentary or igneous rocks can be remelted to form magma, beginning at the beginning

again.

Hope this helps!

the median of the data is 4.5.
