A group of scientists discovered three fossils with very similar characteristics. The fossils are from a species that lived between 10,000 and 40,000 years ago. The scientists want to determine the precise age of these three fossils to determine how the species changed over time. Which method should the scientists use to determine the precise age of these fossils?

Back

carbon dating

Based on the graph, what is true about P waves and S waves?

Back

They travel at different speeds through the Earth.

What type of rock are mid-ocean ridges made of? A divergent plate boundary is a boundary at which two tectonic plates move away from each other. As the plates move apart, magma rises upward between them and erupts onto the ocean floor as lava. This lava cools quickly to form solid rock. Over time, these hardened lava flows build up on top of each other and are uplifted by tectonic forces to form mid-ocean ridges.
