• all of the layers are the same age.

• the bottom layers are younger than the top layers.

• the bottom layers are older than the top layers.

The Law of Superposition helps scientists to determine what?

• The absolute age of rock layers

• The age of fossils

• The relative age of rock layers

• the super powers of rocks

If layer W is 100 million years old and layer Z is 500 million year old, how old is layer X?

• over 500 million years old

• under 100 million years old

• there is no way to estimate the age of layer X

• between 100 and 500 million years old
