Relative Dating

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

Relative dating of rock layers tells us that the deeper we dig, _______.

• the younger the rocks get
• the smellier the rocks get
• the harder the rocks get
• the older the rocks get

The Geologic Time Scale is a record of what?

• old geologists
• sweet geology music
• the known history of rocks and fossils
• a list of every living thing ever

How old do Paleontologists believe the Earth is?

• 2015 years old
• 3.6 billion years old
• 4.6 billion years old
• 4.6 million years old

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

The process by which running water, wind, or ice carry away bits of broken-up rock

• weathering
• sedimentation
• erosion
• cementation

A break in the Earth's crust 

• fault 
• mountain
• plate
• fossil 

Geologist study ancient rocks to learn about:

• people
• environments
• sediments
• cementation

How do scientists figure out the relative age of rocks/fossils?

• Use the Law of Superposition
• Use the Law of Uniformitarianism
• Use Catastrophism
• Use Original Horizontality
