Relative Age of Rocks 1

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

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

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

• F

• Sedimentary
• Igneous
• Metamorphic

The ________ states that layers of sediment were originally deposited horizontally under the action of gravity.

• law of superposition
• law of horizontality 
• uniformitarianism 
• unconformities
