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. 2 / 20 What evidence did Wegener use to support his theory? Mountain ranges and rocks line up across continents All answers are correct Continents and fossils fitting together/matching-up like puzzle pieces Glacier scars and other climate evidence from temperature 3 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up. islands Mountain Ranges Lakes Hills 4 / 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. There was no data showing the continents ever moved. The scientist presenting the data was unreliable. The scientists did not know the force responsible for moving the continents. 5 / 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 6 / 20 Which scientist suggested that Earth's surface used to be formed of one huge supercontinent? Alfred Wegener Isaac Newton Blaise Pascal Albert Einstein 7 / 20 What did Alfred Wegener observe to form his continental drift hypothesis? The coastlines of the continents match The continents are moving slowly infront of him The air movement on Earth causes the supercontinent to split and drift into pieces Huge objects from space hit the Earth's surface and split the huge continent 8 / 20 What was Alfred Wegenerś Continental Drift theory? Pangaea was formed around 250 million years ago All answers are correct The continents have since drifted apart to their current location The continents used to be joined together to form a supercontinent. 9 / 20 Why did no one believe Wegener's theory? His data was wrong He didn't use the right technology to gather data He didn't have evidence He could not explain HOW the continents moved 10 / 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. 11 / 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 12 / 20 Wegener's idea that Pangaea separated into continents became the continental drift .................... theory hypothesis fact law 13 / 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. 14 / 20 .......................... are long, narrow depressions on the seafloor. Ocean trenches Mid-ocean ridges Glossopteris Plate tectonics 15 / 20 The fact that similar fossils are found on both sides of the ocean is evidence of____. Oceanic drift Magnetic reversal Seafloor spreading Continental drift 16 / 20 What two specific continents fit together most noticeably? Antartica and Africa South America and Africa Africa and North America South America and Europe 17 / 20 Fossil plants on different continents are evidence of Continental Drift: TRUE FALSE 18 / 20 Most geologists think that the movement of Earth's tectonic plates is caused by Subduction. The Earth's magnetic field. The rotation of the Earth. Convection currents. 19 / 20 What is the force that moves the continents? Radiation Conduction Conveyor belts Convection 20 / 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 the name of an ancient organism It was 2 separate landmasses, one on the Northern Hemisphere and one on the Southern Hemisphere. Your score is 0% Restart quiz Go to the Quizzes Page
