How does the rock cycle work?

Answer 1

The rock cycle is the natural process in which rocks transform from one rock type into another rock type over time, a type of natural recycling.

Igneous rocks, which are formed from magma cooling underground, or lava above ground are formed from previous igneous, metamorphic, or sedimentary rocks which have become melted, usually as a result of plate collision and subduction.------->

When these igneous rocks are exposed to weathering and erosion, they break down into smaller particles that are transported by wind and water to a place of deposition, where they can form into sedimentary rock strata, through a process of lithification, where excess water is squeezed out by overburden pressures and the particles are cemented together by various minerals precipitating out of solution. Igneous and metamorphic rocks can both be turned into sedimentary rocks in this way.------->

Igneous and sedimentary rocks can also be changed by heat and/or pressure into metamorphic rocks, by transforming their existing mineral structures into new minerals or realigning the existing minerals. There are different degrees of metamorphism, so even an existing metamorphic rock can become a different metamorphic rock. -------->

If these metamorphic rocks are melted, then solidify, they become igneous rocks, and the cycle starts all over again.

The rock cycle is largely driven by lithospheric plate movements which cause subduction and uplift, also by climatic conditions and the associated erosional elements.

Answer 2

This is a continuous process, so there is no beginning or ending. Sedimentary rock is subjected to heat and pressure, which changes it into Metamorphic rock. The metamorphic rock then melts and turns into magma. The magma cools and it turns into igneous rock. If it cools underground, it is intrusive. If it cools above ground, then it is extrusive. Then when the rock is broken up or weathered or destroyed in some way, it is sediment. The sediment combines and cements to become sedimentary rock again.

Answer 3

A rock begins as magma. Then it cools. Crystals form, then become igneous rocks. They break down into sediment which become sedimentary rocks. Then that may become metamorphic rock if subjected to heat and/or pressure from plate-tectonic activity. Then finally, it melts into magma, and the rock cycle starts again.

Answer 5

Rocks change in the rock cycle by intense heat, pressure, or erosion. Rocks become either igneous or metamorphic through heat/pressure, and sedimentary rocks are formed when rocks erode and compress together to form a new rock.
