The Earth's magnetic field. The rotation of the Earth. Subduction. 2 / 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). 3 / 20 What was Alfred Wegenerś Continental Drift theory? All answers are correct 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 4 / 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. Climate change caused the earth's continents to move Remains of plants and animals are found in climates which they could not have survived It was colder at the equator during pangea 5 / 20 Which scientist suggested that Earth's surface used to be formed of one huge supercontinent? Albert Einstein Alfred Wegener Blaise Pascal Isaac Newton 6 / 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 7 / 20 What two specific continents fit together most noticeably? Antartica and Africa South America and Africa Africa and North America South America and Europe 8 / 20 Why did no one believe Wegener's theory? He didn't have evidence His data was wrong He didn't use the right technology to gather data He could not explain HOW the continents moved 9 / 20 Mountain ranges located on both side of the Atlantic Ocean are the same height and width. have ancient fossils and coal seams. are just separate mountain ranges. have the same rock types, structures and ages. 10 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up. Mountain Ranges Lakes Hills islands 11 / 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 12 / 20 .......................... are long, narrow depressions on the seafloor. Ocean trenches Mid-ocean ridges Glossopteris Plate tectonics 13 / 20 This is a picture of glacier scars found in Africa. What are these evidence for? Africa has always been near the equator Africa was once in an area of the Earth that had a very cold climate Sea floor spreading The continents have not moved 14 / 20 The fact that similar fossils are found on both sides of the ocean is evidence of____. Continental drift Seafloor spreading Oceanic drift Magnetic reversal 15 / 20 Fossil plants on different continents are evidence of Continental Drift: TRUE FALSE 16 / 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 17 / 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. 18 / 20 Wegener's idea that Pangaea separated into continents became the continental drift .................... law theory fact hypothesis 19 / 20 What is the force that moves the continents? Conveyor belts Convection Conduction Radiation 20 / 20 Which statement is TRUE about Pangaea? 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 continent that was covered with water in the past. Pangaea is a supercontinent that covered all the Earth's surface in the past.
