Sedimentary Rocks

ROCKS
Sedimentary rock is made up of pieces of older rocks.
It consists of separate grains in layers

Slide 13 - Slide

Sedimentary rocks are porous – they have gaps between grains.
Because the grains are usually rounded the rocks are soft – they can easily be scratched

Slide 14 - Slide

There are many different types of sedimentary rocks. Their appearance depends on the pieces of rock (sediments) from which they are formed.
