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