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