The illustration here shows rock layers in their original order, along with a fracture in some rock layers caused by an earthquake. Based on the evidence in the illustration, an earthquake occurred -

• before layer W was deposited.

• before layer X was deposited

• after layer Y was deposited.

• after layer Z was deposited.

When examining rock layers, you will find the oldest layers at the bottom. Newer minerals and rock are piled on top and, over time, this creates distinct rock layers. This is called _______.

• The Law of Superstition

• The Law of Suspicion

• The Law of Horizontality

• The Law of Superposition

Fossils of trees were discovered in a sedimentary rock layer, and in a rock layer below were fossils of clams. Based on this evidence, what conclusion can be made about the sequence of climates in the past in the area where the fossils were discovered?

• Based on the evidence, it can be assumed that this area was an underwater forest.

• Based on the evidence, it can be assumed that this area was a forest before it was a beach or ocean.

• Based on the evidence, it can be assumed that this area was an ocean or beach before it was a forest.

Which statement is true?

• The oldest layers of rock and soil are closest to the surface of the earth
• The youngest layers of rock and soil are farther away from the surface of the earth.
• Carbon-14 dating is an example of relative dating, and the law of superposition is an example of absolute dating.
• Absolute geologic dating and relative geologic dating are two methods used by scientists to determine the age of geologic evidence.
