If sediment is deposited at 2cm per yr.@the mouth of a river, what do you predict will happen?

The sediment will build up and create a delta.

If examining layers of sedimentary rock for fossils, which fossil would be the oldest?

The fossil found in the bottom layer

Why is it important to conserve fossil fuels.

They will run out one day if we don't conserve them

This statement is true: burning fossil fuels releases energy that originally came from the sun.

fossil fuels come from plant and animal remains.
