How are each Metamorphic,Sedimentary,and Igneous rocks formed?

Answer 1

Hi. Igneous rocks come from molten lava (think ignition), sedimentary is deposited, usually at the bottom of the sea but also in deserts and becomes sand stone, and metamorphic are formed as pressure and heat transform stone.

Answer 2

igneous: form when magma or lava cool to a solid form, either glass or masses of tightly intergrown mineral crystals.
sedimentary: form mostly when chemical residues and fragments of plants, animals, or rocks are compressed or naturally cemented together.
metamorphic: rocks deformed or changed from one form to another by intense heat, pressure and/or the action of hot fluids.
