Relative Age

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

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

_{Which rock layer in the diagram seems to be the oldest?}

• F
• E
• B
• A

_{^{When scientists use logic to determine the age of one fossil compared to another, they use this type of dating.}}

• Relative
• Carbon
• Absolute

_{What can scientists learn from the sequence of rock layers?}

• Geologic history of that area
• Future geological events
• the number of organisms that live in the area
• the impact that hikers have had on an area.
