Mid- Ocean Ridge Continental Shelf Atlantic Trench Abyssal Plain 2 / 20 What of the following is found in the ocean floor? ice glacier only ocean trench mid-ocean ridge plate boundaries 3 / 20 Why was the evidence of seafloor spreading so important to the idea of Continental Drift? A theory stating that Earth’s crust is broken up into large solid plates that move slowly It answers the question for HOW continents could be moving. It disproved Alfred Wegener's hypothesis of Continental Drift. It shows how land bridges let prehistoric animals cross the oceans. 4 / 20 What do the shades found on the maps discovered by a sonar represent? different depths of the ocean presence of green plants ridges and ocean trenches presence of living things 5 / 20 Wegener's idea that Pangaea separated into continents became the continental drift .................... fact theory hypothesis law 6 / 20 The .............................  is a seafloor mountain system formed by lava as it rises from cracks in the surface and cools. ocean trench ocean groove ocean valley mid-ocean ridge 7 / 20 What is geology? the study of rocks the study of maps the study of history the study of earth 8 / 20 What did Marie Tharp's work represent for the continental drift hypothesis? Marie Tharp measured the speed and the direction of the continents' movement. There is no relation between Marie Tharp's work and the continental drift hypothesis. Tharp’s work was the final proof to support the continental drift hypothesis. Marie Tharp mapped the location of the continents on the Earth's surface. 9 / 20 When did scientists suggested that mid-ocean ridges were created by seafloor spreading? in 1960 in 1900 in 1930 in 1910 10 / 20 How did scientists discover the presence of mountain ranges on the ocean floor? They dived in and examined the bottom of the ocean. They used a ship that captures pictures of the ocean floor. They could easily see the ocean floor from the surface. They used an echo sounder which sends a sound wave pulse that hits the ocean bottom. 11 / 20 How do the ages of rocks change as you get further from the Mid-Ocean ridge? Rocks get older Rocks stay the same age Rocks get younger 12 / 20 Which scientist discovered mountain ranges located the ocean floor and developed the theory of seafloor spreading? Isaac Newton Marie Tharp Charles Darwin Alfred Wegener 13 / 20 Which is the deepest point on earth? Iceland mid-ocean ridge The Mid-Atlantic ridge Antarctica The Challenger Deep 14 / 20 Which of the following were pieces of evidence used by Alfred Wegener to support his hypothesis of Continental Drift? (choose ALL that apply) fit of the continents matching rocks and mountains across continents evidence of glaciers in places now too warm matching fossils across continents 15 / 20 In the Atlantic ocean, where is the youngest seafloor located? Young seafloor is located randomly throughout the ocean. Towards the middle of the ocean at ocean ridges. Towards the edges, near the eastern and western continents. Towards the north and south poles. 16 / 20 The technology used to map the ocean floor from ships in 1946 was........... Artificial intelligence GPS Sonar Ocean maps 17 / 20 Choose the correct order of discoveries that led to the overall theory of plate tectonics: formation of the continents - continental drift - mid-ocean ridge continental drift - hotspots and transform boundaries - seafloor spreading seafloor spreading - hotspots and transform boundaries - continental drift continental drift - seafloor spreading - hotspots and transform boundaries 18 / 20 What is sonar? A device using UV rays. A device to measure sound. A device that detects life. A device using sound waves to measure distance. 19 / 20 What discovery revived Wegener's idea of Continental Drift and eventually led to the Theory of Plate Tectonics? The Discovery of America The Discovery of mid-ocean ridges and seafloor spreading The Discovery of new fossils on Africa and South America The Discovery of radioactive isotopes 20 / 20 Why wasn't Marie Tharp allowed on the seagoing expeditions? They thought women brought bad luck at sea She didn't know how to swim She got seasick easily She was pregnant at the time and they thought it would be bad for her health Your score is 0% Restart quiz Go to the Quizzes Page
