What role do faults play in the Law of Superposition?

• Faults create new types of rock.
• Faults are younger than the layers they cut through.
• Faults are the same age as the layers they cut through.

Many fossils of large amphibians were found in an area that is currently barren desert. Which is most likely true?

• The climate of the area was once much wetter than it is now.
• Amphibians were once better at surviving in dry environments.
• The amphibians migrated there after a catastrophic event destroyed their habitats.
• The amphibians are not native to the area and their bones were brought there by other animals.

The idea states the same processes that occurred in the past operate in the same way as they do in the present.

• Absolute Dating
• Relative Dating
• Catastrophism
• Uniformitarianism

Fossils can tell us all of the following information about an organism except:

• How the animals might have traveled
• What kinds of food the organism eats
• What type of environment the organism may have lived in
• The organism's life expectancy (or how long the organism will live) 

Several different fossils were found in rock layers in a geologic column.  Above these rock layers, the fossils were almost nonexistent.  Which most likely explains these observations?

• A nonconformity occurred
• All the organisms migrated.
• A period of mass extinction occurred.

Which generalization can be made about the relative age of a fossil found in a sedimentary rock bed?

• The fossil is younger than the rock layer above it.
• The fossil was formed before the rock layer that contains it.
• The fossil and the rock were formed in different environments.
• The fossil was formed around the same time as the rock that contains it.
