Hi RAB,

  First let us do a little experiment. Take a glass of water and put a few pebbles in it. Do the pebbles dissolve in the water or do they settle down at the bottom of the glass? Yes, they do! This settled down material is called sediment. It is a perfect example of how sedimentary rocks are formed.

Sedimentary rocks are formed by layers of sediment. Sediment is comprised of small parts of rock, as well as dead animals or plants which have been eroded by strong winds and as strong flow of water in rivers and glaciers. Most of these particles get deposited on the sea bed and as more and more of these particles settle on each other, they press on each other and compression happens. The sediments at the bottom change into sedimentary rocks.This process takes thousands of years I hope this helps. Bye!
