TYPE OF ROCKS

Lesson Summary

  • There are three main types of rocks: igneous, sedimentary, and metamorphic.
  • Melting and later cooling, erosion and sedimentation, and metamorphism transform one type of rock into another type of rock or change sediments into rock.
  • The rock cycle describes the transformations of one type of rock to another.
