Pangaea was formed around 250 million years ago The continents have since drifted apart to their current location The continents used to be joined together to form a supercontinent. All answers are correct 2 / 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 Sea floor spreading The continents have not moved Africa has always been near the equator 3 / 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. The scientists did not know the force responsible for moving the continents. There was no data showing the continents ever moved. The scientist presenting the data was unreliable. 4 / 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 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 5 / 20 What is the force that moves the continents? Conduction Conveyor belts Convection Radiation 6 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up. Hills Lakes islands Mountain Ranges 7 / 20 What evidence did Wegener use to support his theory? Continents and fossils fitting together/matching-up like puzzle pieces All answers are correct Mountain ranges and rocks line up across continents Glacier scars and other climate evidence from temperature 8 / 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. 9 / 20 Most geologists think that the movement of Earth's tectonic plates is caused by The rotation of the Earth. The Earth's magnetic field. Subduction. Convection currents. 10 / 20 Why did no one believe Wegener's theory? He didn't use the right technology to gather data He could not explain HOW the continents moved His data was wrong He didn't have evidence 11 / 20 The fact that similar fossils are found on both sides of the ocean is evidence of____. Continental drift Oceanic drift Seafloor spreading Magnetic reversal 12 / 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 one of the continents that are found nowadays. Pangaea is a supercontinent that covered all the Earth's surface in the past. 13 / 20 .......................... are long, narrow depressions on the seafloor. Glossopteris Ocean trenches Mid-ocean ridges Plate tectonics 14 / 20 What was Pangaea? 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. It was the name of an ancient organism 15 / 20 What two specific continents fit together most noticeably? Antartica and Africa South America and Africa Africa and North America South America and Europe 16 / 20 What evidence from the climate supports the idea that the continents were once joined and then drifted apart? Choose all that apply. 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. Climate change caused the earth's continents to move It was colder at the equator during pangea 17 / 20 Which scientist suggested that Earth's surface used to be formed of one huge supercontinent? Blaise Pascal Albert Einstein Isaac Newton Alfred Wegener 18 / 20 Fossil plants on different continents are evidence of Continental Drift: TRUE FALSE 19 / 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. 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
