The diagram shows how layers of rock are formed and that they can contain preserved parts of animals and plants which we call fossils.

Now look at the three diagrams below. These show how erosion of mountains makes sediment, which is then deposited in the basin.

How long did it take for the erosion to go from Diagram 1 to Diagram 3?

• Many weeks

• Many years

• Many hundreds of years

• Many millions of years

The diagram shows how layers of rock are formed and that they can contain preserved parts of animals and plants which we call fossils.

Now look at the three diagrams below. These show how erosion of mountains makes sediment, which is then deposited in the basin.

Where did the sediment shown in the basin in Diagram 2 come from?

• the center of Earth

• animals digging/burrowing

• humans leaving rubbish

• the mountain wearing away
