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

Where would law of superposition be more useful than radioactive dating?

• used to tell which hill peak is the nearest

• used to tell the exact age of your family

• used to tell which layer of sedimentary rock in the grand canyon is the oldest

• used to tell whether two animals that lived in different continents are related
