Law of Superposition & Absolute Dating of Rock

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

This rock was formed by smaller pieces of rock that settled at the bottom of a lake millions of years ago. What type of rock is this?

• Igneous
• Metamorphic
