The 3 types of rocks in the rock cycle are igneous, sedimentary, and metamorphic. Igneous rocks form from cooled magma or lava. Sedimentary rocks are created from the compaction and cementation of various sediment types. Metamorphic rocks develop when existing rocks are subjected to high heat, pressure, or chemically active fluids, altering their original structure and composition.

FAQs & Answers

  1. What is the rock cycle? The rock cycle is a natural process that describes how rocks are formed, broken down, and transformed over time.
  2. How do igneous rocks form? Igneous rocks form from the cooling and solidification of molten rock material, either magma beneath the surface or lava at the surface.
  3. What are sedimentary rocks made of? Sedimentary rocks are made of particles and organic material that have been compacted and cemented over time.
  4. What changes do metamorphic rocks undergo? Metamorphic rocks undergo changes in structure and composition due to exposure to high heat, pressure, or chemically active fluids.
