What is the Rock Cycle?

  • The rock cycle is a way that rocks change from one type to another over a long time.
  • There are three main types of rocks: igneous, sedimentary, and metamorphic.
  • Rocks can melt, break, and change due to heat and pressure.

Examples:

  • Igneous rocks, like granite, are formed when melted rocks cool down.
  • Sedimentary rocks, like limestone, are made from tiny pieces of rocks that stick together.
  • Metamorphic rocks, like marble, are made when heat and pressure change existing rocks into something new.

Fun Fact: The rock cycle can take millions of years, and it never stops! Just like how the weather changes, rocks can change, too.
