Isaac Newton Alfred Wegener Blaise Pascal Albert Einstein 2 / 20 Most geologists think that the movement of Earth's tectonic plates is caused by Subduction. The rotation of the Earth. The Earth's magnetic field. Convection currents. 3 / 20 The fact that similar fossils are found on both sides of the ocean is evidence of____. Seafloor spreading Magnetic reversal Continental drift Oceanic drift 4 / 20 .......................... are long, narrow depressions on the seafloor. Glossopteris Mid-ocean ridges Plate tectonics Ocean trenches 5 / 20 Wegener's idea that Pangaea separated into continents became the continental drift .................... fact hypothesis law theory 6 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up. Lakes Mountain Ranges Hills islands 7 / 20 Originally the Continental drift theory was not well received by other scientists. Why? The scientist presenting the data was unreliable. There was a competing theory at the time that was more believable. The scientists did not know the force responsible for moving the continents. There was no data showing the continents ever moved. 8 / 20 Which statement is TRUE about Pangaea? Pangaea is one of the continents that are found nowadays. Pangaea is a supercontinent that covered all the Earth's surface in the past. Pangaea is a continent that was covered with water in the past. Pangaea is a supercontinent that split and drifted apart to form the continents. 9 / 20 What two specific continents fit together most noticeably? South America and Europe Africa and North America South America and Africa Antartica and Africa 10 / 20 According to the continental drift hypothesis, the presence of similar fossils in South America and Africa supports which scientific idea? Animals easily and frequently travel from Africa to South America. South America and Africa were once connected together. Species of animals probably traveled between continents on natural rafts (such as trees destroyed in tsunamis). Land bridges once existed that connected the continents. 11 / 20 Mountain ranges located on both side of the Atlantic Ocean are the same height and width. have ancient fossils and coal seams. are just separate mountain ranges. have the same rock types, structures and ages. 12 / 20 Fossil plants on different continents are evidence of Continental Drift: FALSE TRUE 13 / 20 Why did no one believe Wegener's theory? He didn't have evidence He could not explain HOW the continents moved He didn't use the right technology to gather data His data was wrong 14 / 20 What evidence did Wegener use to support his theory? Mountain ranges and rocks line up across continents Continents and fossils fitting together/matching-up like puzzle pieces All answers are correct Glacier scars and other climate evidence from temperature 15 / 20 What was Pangaea? It was the name of an ancient organism It was a supercontinent made of 3 landmasses It was a supercontinent, made of all of the landmasses on Earth. It was 2 separate landmasses, one on the Northern Hemisphere and one on the Southern Hemisphere. 16 / 20 What did Alfred Wegener observe to form his continental drift hypothesis? The air movement on Earth causes the supercontinent to split and drift into pieces Huge objects from space hit the Earth's surface and split the huge continent The coastlines of the continents match The continents are moving slowly infront of him 17 / 20 This is a picture of glacier scars found in Africa. What are these evidence for? The continents have not moved Sea floor spreading Africa has always been near the equator Africa was once in an area of the Earth that had a very cold climate 18 / 20 What is the force that moves the continents? Convection Radiation Conduction Conveyor belts 19 / 20 What evidence from the climate supports the idea that the continents were once joined and then drifted apart? Choose all that apply. Evidence of glaciers are found on continents that are in tropical regions of the earth. It was colder at the equator during pangea Climate change caused the earth's continents to move Remains of plants and animals are found in climates which they could not have survived 20 / 20 What was Alfred Wegenerś Continental Drift theory? The continents used to be joined together to form a supercontinent. All answers are correct Pangaea was formed around 250 million years ago The continents have since drifted apart to their current location Your score is 0% Restart quiz Go to the Quizzes Page
