What are the parts of the rock cycle? How does the rock cycle work?
Rock cycle is the continuous changing of rocks from one type to another.
All igneous rocks on the earth began deep within the earth as magma. Some of the magma cooled and hardened beneath the earth's surface. Some of it reached the surface and cooled. Igneous rocks beneath or on the earth's surface are constantly subjected to physical and chemical conditions that change them. As a result of these changes sedimentary, metamorphic, and new igneous rock are formed.
