Oceanography Unit 2 Test Study Guide *This is not a mandatory and is not a grade, but is highly recommended. I will add up to 10 bonus points to your classwork grade for completing this study guide. Part 1: Formation of the Ocean 1. What is the supercontinent named in the Theory of continental drift? Pangea 2. What is the force that makes magma in Earth’s mantle move, due to heating and cooling? Convection 3. A) Which layer of the earth makes a tectonic plate that is rigid and can move? Lithosphere 4. A) What type of plate boundary occurs where two pieces of oceanic crust move apart? Divergent 5. A) What type of plate boundary creates a fault or cliff? Transform B) What type of plate boundary creates a trench? Convergent C) What type of plate boundary creates a mid-ocean ridge? Divergent 6. A) Which ocean was created when North America separated from Eurasia? Atlantic Ocean 7. How many oceans exist in the world? Five 8. What is a body of brackish water called? Lagoon Part 2: Ocean Floor 1. Which ocean zone is closest to the shore? Intertidal 2. A) Which ocean zone has an area of sunlight? Pelagic Zone B) What is it called? Photic 3. A) Which ocean zone is referred to as the “open ocean?” Pelagic Zone B) Which ocean zone is referred to as the “ocean floor” or bottom of the ocean? Benthic Part 3: Islands 1. What is a volcano that forms in the middle of a plate, where magma rises upward until it erupts on the sea floor? Hot Spot 2. *Explain how a hot spot created the Hawaiian Island Chain. You can draw a picture to explain. Hotspots do not move but the plates continue to shift. This created the island chain because the initial island was broken by an eruption + plate shift and then it continued this pattern towards the Northwest, creating barrier islands. 3. What is formed when a piece of the mainland is broken off and separated by a body of water? Barrier Island 4. A) What type of reef forms when an island sinks below sea level? Atoll B) What type of reef forms along the coast or an island? Fringing C) What type of reef is separated by land with a body of water? Barrier D) What type of reef is the most common? Fringing 5. We have lost what percentage of corals overall in Florida? 90% in Florida 6. In the Corals video what was the only thing researchers could find that could cause corals to turn white? Climate change causing zooxanthellae to leave the coral due to increase in temperature 7. What is the largest structure ever made by life on earth? Coral reef 8. What is the Coral bleaching phenomenon directly attributed to Climate change 9. What is driving global climate change? Fossil fuels 10. What percentage of corals on the Great Barrier Reef died in 2016? 30% 11. Which fish eats the coral and turns it into sand? Parrotfish *Label the diagram of the ocean floor F B D A _____Continental Shelf ____Seamounts ____Rift Valley ______Continental Slope E C ______ Volcanic Island ______Abyssal Plain G _______Trench Label the type of reefs correctly Fringing Atoll Barrier Fringing Barrier Atoll
