Geological Features

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

What type of rock do fossils form in?

• Igneous
• Sedimentary
• Metamorphic
• Classic

According to the law of superposition, which layer is the youngest?

• A
• B
• C

Based on the law of superposition, where would the oldest rocks be found.

• at the bottom

• at the top

• second from the bottom

• second from the top

Which letter matches with the OLDEST layer of rock?

• W

• X

• Y

• Z

Analyze the seashell found in the white layer.  Which statement is true of the rock layer that contains this fossil?

• It could also contain a fossil from the bottom layer.
• It is older than the layers below it.
• It is younger than the layers above it.
• It is older than the layers above it.

What are the relative ages of the features in order from oldest to youngest?

• Limestone, Basalt, Fault, Siltstone
• Siltstone, Fault, Basalt, Limestone
• Limestone, Fault, Basalt, Siltstone
• Limestone, Siltstone, Fault, Basalt

How does the law of crosscutting explain the age of a fault?

• The fault is younger than the rocks above it.
• The fault is younger than the rocks it cuts through.
• The fault is older than the rocks above it.
• The fault is older than the rocks it cuts through.

This is the movement of sediment by wind, water, and gravity.

• deposition

• constructive

• erosion

This is the dropping of sediment by wind, water, or ice.

• deposition

• constructive

• erosion
