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