Chapter 3 Plate Tectonics Study Guide – Test Friday Oct 21 Two plates come together at a ____________ boundary Two plates slip past each other at a __________ boundary Two plates move apart at a ___________ boundary Convergent boundary between two continental plates produces… A divergent boundary on land produces… Wegener’s continental drift hypothesis states… The name of the supercontinent that existed millions of years ago… Describe the 3 clues that support Wegener’s hypothesis of continental drift? Scientists think the Earth’s plates move because of… In the 1900’s what technology was used to map the ocean floor? What is the temperature and density difference between new and old oceanic crust? Describe the process that occurs at a mid ocean ridge. Describe the process that occurs at a deep ocean trench. The theory of plate tectonics states… Describe the 3 kinds of evidence that supports the occurrence of sea floor spreading. ___________ continually adds new crust to the ocean floor and occurs at a _________________ _________ occurs when ocean floor sinks back into mantle at a _________________ What is formed when two oceanic plates collide? What is formed when two continental plates collide? What is formed when an oceanic and continental plate collide? Be able to identify boundaries, and land features on a diagram.
