The Rock Cycle

The Earth was formed approximately 4,600 million years ago, as a sphere of molten rock.

  • The first solid rocks to form at the Earth’s surface crystallised from molten magma.
  • Processes at or beneath the Earth’s surface modify rocks and transform them into other materials or rock types.
  • These processes contribute in The Rock Cycle, as illustrated below.
