Why? 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. The scientists did not know the force responsible for moving the continents. 2 / 20 Most geologists think that the movement of Earth's tectonic plates is caused by Convection currents. Subduction. The Earth's magnetic field. The rotation of the Earth. 3 / 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. Species of animals probably traveled between continents on natural rafts (such as trees destroyed in tsunamis). Land bridges once existed that connected the continents. 4 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up. islands Mountain Ranges Lakes Hills 5 / 20 What two specific continents fit together most noticeably? Antartica and Africa South America and Africa South America and Europe Africa and North America 6 / 20 Which statement is TRUE about Pangaea? Pangaea is one of the continents that are found nowadays. 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. 7 / 20 Why did no one believe Wegener's theory? He didn't have evidence His data was wrong He could not explain HOW the continents moved He didn't use the right technology to gather data 8 / 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. Remains of plants and animals are found in climates which they could not have survived It was colder at the equator during pangea Climate change caused the earth's continents to move 9 / 20 What is the force that moves the continents? Radiation Convection Conveyor belts Conduction 10 / 20 Wegener's idea that Pangaea separated into continents became the continental drift .................... fact law theory hypothesis 11 / 20 .......................... are long, narrow depressions on the seafloor. Mid-ocean ridges Ocean trenches Glossopteris Plate tectonics 12 / 20 What evidence did Wegener use to support his theory? All answers are correct Glacier scars and other climate evidence from temperature Continents and fossils fitting together/matching-up like puzzle pieces Mountain ranges and rocks line up across continents 13 / 20 Fossil plants on different continents are evidence of Continental Drift: FALSE TRUE 14 / 20 Which scientist suggested that Earth's surface used to be formed of one huge supercontinent? Albert Einstein Isaac Newton Alfred Wegener Blaise Pascal 15 / 20 The fact that similar fossils are found on both sides of the ocean is evidence of____. Magnetic reversal Oceanic drift Seafloor spreading Continental drift 16 / 20 Mountain ranges located on both side of the Atlantic Ocean are just separate mountain ranges. have ancient fossils and coal seams. are the same height and width. have the same rock types, structures and ages. 17 / 20 What did Alfred Wegener observe to form his continental drift hypothesis? The coastlines of the continents match 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 18 / 20 This is a picture of glacier scars found in Africa. What are these evidence for? The continents have not moved Africa was once in an area of the Earth that had a very cold climate Africa has always been near the equator Sea floor spreading 19 / 20 What was Alfred Wegenerś Continental Drift theory? Pangaea was formed around 250 million years ago The continents have since drifted apart to their current location All answers are correct The continents used to be joined together to form a supercontinent. 20 / 20 What was Pangaea? It was 2 separate landmasses, one on the Northern Hemisphere and one on the Southern Hemisphere. It was a supercontinent made of 3 landmasses It was the name of an ancient organism It was a supercontinent, made of all of the landmasses on Earth.
