Graph of Neodymium and Strontium Ratios in Sediments

Actvity Summary: Students will use data from deep sea cores to interpret a graph. Students will apply their knowledge of isotopes to understand how scientists use chemistry to discover the origins of ocean sediments and infer changes in climate.
