Evidence for the age of the Earth

T/F: Geologist use radioactive dating to find the absolute age of rocks

• True

• False

Some ELEMENTS can decay over time.

• True

• False

Meteorites have clues about our planet's past.

• true

• false

The bottom layer is listed as the oldest. The top layer is listed as the youngest. What is this called?

• mineral content

• radioactive decay 

• the law of superposition 

• the principle of unconformity 

The Law of Superposition helps scientists to determine what?

• The absolute age of rock layers

• The age of fossils

• The relative age of sedimentary rock layers

• the super powers of rocks

According to the law of superposition, the oldest fossils are found 

• At the top of the rock layers

• Near the bottom of the rock layers

• In the middle of the rock layers

• Somewhat near the surface

• A

• B

• C
