The Rockcycle

Weathering & Erosion. Igneous, sedimentary, and metamorphic rocks on the surface of the earth are constantly being broken down by wind and water
Igneous rocks are formed from cooled magma and are often either very rigid or porous depending on the place of cooldown. They have minerals in the form of crystals which are often very visible
When Igneous, Sedimentary or Metamorphic rocks undergo immense pressure and heat, the shape of the rocks change. Under such circumstances, some of the properties of the rocks change giving rise to new forms of rock known as metamorphic rocks. The process might even repeat on metamorphic rocks again.
Rocks that are formed from constant sedimentation followed by increased pressure and heat. Meanwhile, the minerals act as a cohesive agent and thus, sedimentary rocks are formed. The constructing particles can range from sand to pebbles
Weathering and erosiontransportation, deposition, compaction, metamorphism and Rockmelting are part of the rock cycle. 
This is everything we know about the rock cycle. .
