A. weathering and erosion C. volcanic eruption and earthquake B. runoff and flood D. All of the above ___2. What type of climate is favorable for weathering? A. warm and dry B. warm and moist ___3. What type of weathering is frost wedging? A. mechanical B. chemical C. erosion D. sedimentation ___4. How is weathering different from erosion and deposition? A. Weathering is breaking rocks while erosion is grinding of sediments and deposition is settling of sediments. B.

A. sandy loam B. clay C. silty clay D. loam ____14. The mid-ocean ridge in the Atlantic Ocean is a _______________ A. divergent boundary B. convergent boundary ____15. Why was Wegener’s theory forgotten? A. He could not explain how the continents could move. B. He did not publish his theory. ____16. Tectonics plates float on the _____________________ A. outer core B. Inner core C. asthenosphere or mantle D. lithosphere ____17. Why is Earth not growing in spite of sea floor spreading? A. because of subduction in the Atlantic Ocean. B. because of subduction the Pacific Ocean. ____18. The ________ in the asthenosphere is described as a “giant conveyor belt”. A. magma B. convection C. spinning D. lithosphere ____19. Most earthquakes happen along the _____________________, around the Pacific Ocean. A. fault B. volcanic mountains C.

Where is old crust melted back into magma? A. at the mid-ocean ridge B. along plate boundaries C. at deep-sea trenches D. volcano ____24. The theory of plate tectonics combine which two other theories? A. sea floor spreading and continental drift C. continental drift and fossil theory B. sea floor spreading and tidal theory D. continental drift and Big Bang theory ____25.

Magma flows up between the plates and forms new crust. B. Old ocean floor is re-melted into magma 5 points Extra Credit: Do not ask your teacher to explain or elaborate. This is only an extra credit. It is your choice to answer it or not! Do not answer it if you are not willing to think. Define and explain the similarities and differences between a geyser and spring. _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________
