2/10
What does the law of superposition state?

Fossils are only found in the top layer
3/10
What is an index fossil?
THey show the exact age in years of a rock layer
A fossil found only in the deepeset layers
They help determine the relative ages of rock layers

The lower fossil is younger than the one above it
The lower fossil is older than the one above it
Both fossils are the same age
7/10
Why are index fossils useful to geologists?
They help determine the relative ages of rock layers
They show the exact age in years of a rock layer
They are the oldest fossils ever found
8/10
Which statement about the fossil record is TRUE?
It is incomplete because not all organisms fossilize easily
It contains every organism that ever lived
It shows that all life appeared at the same time
9/10
What would make a fossil a good index fossil
It is found in many places and lived for a short time
It lived for a very long period of time
It is rare and only found in one place
10/10
What is the main reason soft-bodied organisms are rarely found as fossils?
They decay quickly and do not preserve well
They turn into rocks immediately after death
They live too deep underground
