The carbon cycle would stop and Earth’s temperature would decrease. (Correct answer: The oceans would flood the land and volcanoes would increase.) Question 5. What two conditions stop carbon dioxide production, lowering Earth’s temperature? a. No mantle motion and no crust movement b. Fast mantle motion and fast crust motion c. Solid outer planetary core and slow crust motion d. No mantle motion and fast crust motion (Correct answer: No mantle motion and no crust movement) Question 6. How does Earth’s geology support human survival? a. It provides radiation for plant growth and creates ocean currents. b. It protects us from the magnetic field and eliminates carbon dioxide. c. It provides a magnetic field and the carbon rock cycle. d. Convection of the mantle causes the Earth to rotate and creates the seasons. (Correct answer: It provides a magnetic f
