Sedimentary rock

• • is formed from magma or lava.

  • Rock from the Earth's crust and mantle becomes molten because of changes in heat and pressure.

  • Some of this molten magma rises up through the Earth's crust.

  • The magma cools down as it rises. Some of it solidifies underground. Some of it rises to the surface as lava before it solidifies.

• is made up of tiny broken pieces of rocks, crystals or minerals. Rock breaks and is eroded into tiny pieces and moved by wind, ice or water.

  • The bits of rock are deposited somewhere new.

  • Deposits build up in layers called sediments.

  • Over millions of years, the layers of sediment become crushed and compacted until they harden to form sedimentary rock. I

• starts out as one type of rock but changes into another. For example, a metamorphic rock can be formed because of high heat or high pressure.
