The Rock Cycle
The Rock cycle is a process in which never stops.
It starts off by being Magma underground.Then it works its way
up, then a volcano would erupt and the magma that has made its way on the Earth's surface would then be called Lava!When the Lava has cooled it then becomes solid, Which is also known as Crystallization. That would form Extrusive Igneous Rock!Weathering and Erosion then breaks down the Igneous Rock (solid rock) which makes it pieces of sediment. The Sediment is transported from a different place like sliding into a stream or river. Then it is deposited into the stream or river creating slow stream flow. The Sediment is then compacted and cemented to form a Sedimentary Rock! This process is called "Lithification". When Sedimentary Rock is pushed deep under the Earth's Crust by geological forces, heat and pressure will cause the Sedimentary Rock to become Metamorphic Rock! If the Metamorphic Rock is pushed deeper in the Earth the Metamorphic rock is then "morphed" into Magma. (Magma is melted Metamorphic Rock). Then the Rock Cycle starts all over again!
Chemical Weathering: Altering of the internal structure of minerals by removing and/or adding elements.
Mechanical Weathering: When Rocks are broken down without any help of chemical forces.
