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