The Earth's magnetic field. The rotation of the Earth. Convection currents. 3 / 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 4 / 20 .......................... are long, narrow depressions on the seafloor. Mid-ocean ridges Glossopteris Plate tectonics Ocean trenches 5 / 20 What was Pangaea? 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 It was a supercontinent made of 3 landmasses 6 / 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 Sea floor spreading Africa was once in an area of the Earth that had a very cold climate 7 / 20 What did Alfred Wegener observe to form his continental drift hypothesis? 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 The air movement on Earth causes the supercontinent to split and drift into pieces 8 / 20 What two specific continents fit together most noticeably? South America and Africa Africa and North America South America and Europe Antartica and Africa 9 / 20 Which scientist suggested that Earth's surface used to be formed of one huge supercontinent? Blaise Pascal Albert Einstein Alfred Wegener Isaac Newton 10 / 20 What is the force that moves the continents? Conduction Radiation Conveyor belts Convection 11 / 20 Wegener's idea that Pangaea separated into continents became the continental drift .................... fact hypothesis theory law 12 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up. Lakes Mountain Ranges islands Hills 13 / 20 What was Alfred Wegenerś Continental Drift theory? The continents used to be joined together to form a supercontinent. The continents have since drifted apart to their current location Pangaea was formed around 250 million years ago All answers are correct 14 / 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 scientist presenting the data was unreliable. There was no data showing the continents ever moved. The scientists did not know the force responsible for moving the continents. 15 / 20 Fossil plants on different continents are evidence of Continental Drift: TRUE FALSE 16 / 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 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. It was colder at the equator during pangea 17 / 20 What evidence did Wegener use to support his theory? Continents and fossils fitting together/matching-up like puzzle pieces All answers are correct Glacier scars and other climate evidence from temperature Mountain ranges and rocks line up across continents 18 / 20 The fact that similar fossils are found on both sides of the ocean is evidence of____. Continental drift Oceanic drift Magnetic reversal Seafloor spreading 19 / 20 According to the continental drift hypothesis, the presence of similar fossils in South America and Africa supports which scientific idea? Animals easily and frequently travel from Africa to South America. South America and Africa were once connected together. Land bridges once existed that connected the continents. Species of animals probably traveled between continents on natural rafts (such as trees destroyed in tsunamis). 20 / 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 continent that was covered with water in the past. Pangaea is a supercontinent that split and drifted apart to form the continents. Your score is 0% Restart quiz Go to the Quizzes Page
