Why do paleontologists use radioactive dating and carbon dating to tell the age of a fossil? What is the difference between carbon dating and radioactive dating of fossils? What type of material has to be present in a rock to use radioactive dating? What type of material has to be present in a rock to use carbon dating? Explain.

How does rain water cause erosion and deposition? a. when acidic water soaks into the ground, water dissolves limestone, resulting in the formation of caves.b. when a river overflows it moves downhill resulting in the formation of caves.c. when it rains, water flows into rivers and streams and moves back to land, resulting in the formation of caves.d. when water empties into lakes, sediment is deposited, resulting in formation of caves.
