The air movement on Earth causes the supercontinent to split and drift into pieces 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 2 / 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. 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. The scientist presenting the data was unreliable. There was no data showing the continents ever moved. 4 / 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. 5 / 20 .......................... are long, narrow depressions on the seafloor. Plate tectonics Ocean trenches Glossopteris Mid-ocean ridges 6 / 20 What is the force that moves the continents? Conveyor belts Convection Radiation Conduction 7 / 20 Wegener's idea that Pangaea separated into continents became the continental drift .................... law fact hypothesis theory 8 / 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. 9 / 20 Fossil plants on different continents are evidence of Continental Drift: FALSE TRUE 10 / 20 What was Alfred Wegenerś Continental Drift theory? The continents have since drifted apart to their current location Pangaea was formed around 250 million years ago All answers are correct The continents used to be joined together to form a supercontinent. 11 / 20 This is a picture of glacier scars found in Africa. What are these evidence for? Africa has always been near the equator Sea floor spreading The continents have not moved Africa was once in an area of the Earth that had a very cold climate 12 / 20 According to the continental drift hypothesis, the presence of similar fossils in South America and Africa supports which scientific idea? Land bridges once existed that connected the continents. 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). 13 / 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 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 14 / 20 What was Pangaea? It was a supercontinent made of 3 landmasses 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 all of the landmasses on Earth. 15 / 20 The fact that similar fossils are found on both sides of the ocean is evidence of____. Continental drift Magnetic reversal Seafloor spreading Oceanic drift 16 / 20 What two specific continents fit together most noticeably? South America and Africa South America and Europe Africa and North America Antartica and Africa 17 / 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 18 / 20 Why did no one believe Wegener's theory? He didn't have evidence He didn't use the right technology to gather data His data was wrong He could not explain HOW the continents moved 19 / 20 Which scientist suggested that Earth's surface used to be formed of one huge supercontinent? Alfred Wegener Albert Einstein Blaise Pascal Isaac Newton 20 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up.
