Mrs. S-F please check # __*_
#All problems are 2 points each unless marked otherwise. CHECK YOUR WORK!
Part I- True/False. Read each statement below carefully. Circle the best answer, “true”, or
“false” and correct the underlined word(s) for one half point of Extra Credit.
true false 1. New ocean crust is formed at a divergent boundary.
true false 2. Rocks found along the Mid-Atlantic Ridge are younger than the oldest known
continental rock.
true false 3. Cooling a material makes it more dense, so it sinks.
true false 4. (1 pt.) The outer core is liquid.
true false 5. Convection currents occur in the asthenosphere of the earth.
true false 6. Non-volcanic mountains are created where plates are moving together
true false 7. The “Ring of Fire” surrounds the Pacific Ocean
true false 8. (1 pt.) Continental plates stay above ocean crust plates because oceanic crust is
denser.
true false 9. (1 pt.) Secondary waves travel more slowly than primary waves
true false 10. Iceland is growing in size due to its location on the Mid-Atlantic Ridge
true false 11. Volcanic island arcs form along divergent plate boundaries
true false 12. The theory of plate tectonics explains the mechanism that moves plates
across the mantle
true false 13. (1 pt.) Convection currents are the heat transfer mechanism which move tectonic
plates.
Part II. Multiple Choice Please clearly WRITE IN CAPITAL LETTERS ( DO NOT ONLY
CIRCLE-it makes it more difficult to correct) the letter of the the best answer for each question.
