Step Description
Step 1:Existing rocks are broken down into
small pieces of sediment.
Step 2:Sediment is transported by wind or
water.
Step 3:Sediment drops out of air or water as the
wind or air out.
Step 4:The sediment is squeezed together
pushing water or air out.
Step 5:Minerals that are dissolved in water stick
to sediment as the water evaporates and
the minerals become solid again.
