2. Why? These two shark teeth were found near Hart Park. Why do you think there are shark teeth buried in the San Joaquin Valley? SJVRocks!! CSUBakersfield Department of Geological Sciences

3. Objective: We will create a model that explains the presence of marine fossils in the San Joaquin Valley using the Plate Tectonic Theory to help us understand the change of geography over time. SJVRocks!! CSUBakersfield Department of Geological Sciences

5. Vocabulary Tectonic Plate: Plate: a large, hard slab of solid rock. Tectonics: comes from the Greek root "to build." Putting these two words together, we get the term plate tectonics, which refers to how the Earth's surface is built of plates.
