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