How do geologists use relative dating?

• Placing rocks in order from youngest to oldest
• Placing rocks in order by minerals they contain
• Classifying rocks by different textures
• Classifying rocks by different isotopes

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
