Geologic Processes 1 (Using Rocks to Tell Time)

The Law of Superposition states that

• the older layers of rock are at the bottom

• the older layer of rock are at the top

• the younger layer of rock is at the bottom

• the younger layer of rock is in the middle

If we want to figure out the age of layers from two different locations what would be the best way to do so?

• We can compare the fossils found in the layers of one location to the fossils in the other location

• We can use the law of superposition to figure out the rate of layer formation

• Radioactive dating to compare the age of the rocks in the layers

• Compare the number of layers in each location

What is relative dating?

• used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages.

• used to determine the precise age of a fossil by using radioactive dating to measure.

• Order of layers from oldest to youngest

• Used to determine the location of the rocks around the world.

Is fossil creation a natural process?

• Yes

• No

• Sometimes

• what is a fossil?

Why may fossil of the same organism be found on different continents?

• Because the continents were once together

• Similar fossils should not be found on different continents

• Because fossils change over time

• Because of the Evolution of the Earth

Which statement is correct

• Layer 2 is younger than layer 4

• Layer 1 is younger than layer 4

• Layer 2 is older than layer 1

• Layer 3 is younger than layer 1

If Scientist we studying bones of animals that became igneous rock fossils. Why would they use radioactive dating to study the igneous rock?

• It is the easiest method to determine age

• The rate of decay in the rock provide an accurate way to calculate age.

• This method tell them the exact age of the rock which is what they are looking for .

• They would use relative dating instead.

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

Traces or remains of organisms that lived long ago

• Fossil
• Unconformity
• Superposition
• Column

How does absolute age differ from relative age?

• only absolute dating indicates which rock is older than another
• only absolute dating finds the age in years
• only relative dating finds the age in years
