Facts about the Rock Cycle

Facts about the Rock CycleMagma that cools beneath the Earthís surface into solid rock does so very, very gradually giving it a course texture. Such rocks are known as intrusive.

In a long term fight between rock and water, water will win every time. Water, whether via surface weathering and erosion or within the groundwater, is quite effective at breaking down rocks.

No matter what type of rock something breaks down from it stays, regardless of how small it gets. Even a grain of sand is the identical class of rock it was as part of a boulder, however once the grains of sand are fused collectively into a bigger mass again it becomes sedimentary.

Water melts minerals and carries ions away to be utilized elsewhere. It also carries sediment to points in which it can collect, accumulate and be buried under pressure and changed back into rock.

Rock Cycle Facts for Kids

Humans make use of rocks for many various things in particular, building materials and roofing. Is it possible to run out of rocks? Even though we should always use natural sources carefully, it's unlikely that we will run out of rocks in the near future.


Magma which swells up to the ocean floor is successfully working both ends of the rock cycle. The magma will cool making a new hard rock, generally basalt. Throughout that process the temperature that is leaving the rock heats up the seawater and as the heated seawater moves through crevices starting the breaking down and metamorphism of that rock into sediment.

The majority of liquid rock that produces it to the surface is normally the least dense magma in the area.

What is the Rock Cycle

The Rock Cycle is several changes. Sedimentary rock can transform into metamorphic rock or into igneous rock. Igneous rock can alter into sedimentary rock or into metamorphic rock. Metamorphic rock can transform into igneous or sedimentary rock. 

Igneous rock forms when magma cools and makes crystals. Magma is a warm liquid made of dissolved minerals. The minerals can build crystals once they cool. Igneous rock can form underground, in which the magma cools gradually. Or, igneous rock can form above ground, in which the magma cools rapidly.

Whenever it pours out on Earth's surface, magma is known as lava. Yes, the identical liquid rock matter that you notice coming out of volcanoes.

On Earth's surface, water and wind can break rock into parts. They also can carry rock pieces to another location. Usually, the rock pieces, known as sediments, fall from the wind or water to create a layer. The layer can be buried beneath other layers of sediments. After a while the sediments can be cemented together to produce sedimentary rock. In this manner, igneous rock can become sedimentary rock.
