Explain models of rock cycle PLEASE HELP
1 answer:
This model explains how igneous rocks are created by magma rising to the surface, where it solidifies. Sedimentary rocks are created by erosive agents and compaction forces. And metamorphic rocks are created by changes in temperature and pressure.
<h3>What is the rock cycle?</h3>
The rock cycle is the geological process through which rocks transform.
During the cycle, rocks suffer transformations that lead them to change from one type to another, turning into igneous, sedimentary, and metamorphic rocks.
The cycle begins when magma rises by convection currents and reaches the Earth's surface where it gets cold, solidifies, and turns into igneous rocks.
Igneous rocks can transform into,
- sedimentary rock ⇒ If they remain on the Earth's surface, and suffer erosion, breaking, and producing small rocky fragments that deposit as sediment.
- metamorphic rocks ⇒ If they get buried under several layers on the ground, suffering changes in temperature and pressure.
- magma ⇒ If they get deeper under the crust and melt due to high temperatures.
Sedimentary rocks are composed of rocky sediments from other rocks and the remains of living beings that get stuck within the sedimentary layers.
Sedimentary rocks can transform into,
- New sedimentary rock ⇒ If they remain on the surface, they suffer erosion and produce new sediment.
- metamorphic rocks ⇒ If they suffer changes in temperature and pressure.
- magma ⇒ If they melt in the deepest areas under the crust.
Finally, metamorphic rocks are produced underground when other rocks suffer changes.
Metamorphic rocks have two destinies,
- If they remain on the surface, they suffer erosion and produce new sediment, turning into sedimentary rocks.
- If they are transported under the crust, they can melt and become magma.
This model explains how these three types of rocks are created and how each of them constantly turns into the other type.
