1. Magmatic rock

(1) Intrusive rock: Rock with better mineral crystallization formed after magma enters the crust and cools and solidifies.

(2) Volcanic rock: volcanic rock, which is formed by contacting the atmosphere or condensing water after magma is ejected from the earth's surface.

2. Sedimentary rock

Sedimentary rocks are those formed by river or glacier erosion, transport, sedimentation, consolidation, and compaction after the exposed rock surface has been damaged by weathering.

3. Metamorphic rock

Metamorphic rocks are new rocks formed by changes in the composition, structure and structure of the original rock due to changes in its geological, physical and chemical environment.
