Why? The scientists did not know the force responsible for moving the continents. There was no data showing the continents ever moved. The scientist presenting the data was unreliable. There was a competing theory at the time that was more believable. 2 / 20 What is the force that moves the continents? Radiation Conduction Convection Conveyor belts 3 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up. islands Hills Lakes Mountain Ranges 4 / 20 This is a picture of glacier scars found in Africa. What are these evidence for? Africa was once in an area of the Earth that had a very cold climate The continents have not moved Sea floor spreading Africa has always been near the equator 5 / 20 What did Alfred Wegener observe to form his continental drift hypothesis? 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 The continents are moving slowly infront of him The coastlines of the continents match 6 / 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. 7 / 20 .......................... are long, narrow depressions on the seafloor. Ocean trenches Mid-ocean ridges Plate tectonics Glossopteris 8 / 20 The fact that similar fossils are found on both sides of the ocean is evidence of____. Oceanic drift Seafloor spreading Continental drift Magnetic reversal 9 / 20 Why did no one believe Wegener's theory? He didn't have evidence He could not explain HOW the continents moved His data was wrong He didn't use the right technology to gather data 10 / 20 Mountain ranges located on both side of the Atlantic Ocean are just separate mountain ranges. are the same height and width. have the same rock types, structures and ages. have ancient fossils and coal seams. 11 / 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 12 / 20 What two specific continents fit together most noticeably? Africa and North America Antartica and Africa South America and Europe South America and Africa 13 / 20 Most geologists think that the movement of Earth's tectonic plates is caused by Convection currents. Subduction. The rotation of the Earth. The Earth's magnetic field. 14 / 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 15 / 20 What was Alfred Wegenerś Continental Drift theory? 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 All answers are correct 16 / 20 What was Pangaea? It was a supercontinent, made of all of the landmasses on Earth. It was the name of an ancient organism It was a supercontinent made of 3 landmasses It was 2 separate landmasses, one on the Northern Hemisphere and one on the Southern Hemisphere. 17 / 20 According to the continental drift hypothesis, the presence of similar fossils in South America and Africa supports which scientific idea? Species of animals probably traveled between continents on natural rafts (such as trees destroyed in tsunamis). South America and Africa were once connected together. Animals easily and frequently travel from Africa to South America. Land bridges once existed that connected the continents. 18 / 20 Fossil plants on different continents are evidence of Continental Drift: FALSE TRUE 19 / 20 Wegener's idea that Pangaea separated into continents became the continental drift .................... theory law hypothesis fact 20 / 20 Which scientist suggested that Earth's surface used to be formed of one huge supercontinent? Albert Einstein Alfred Wegener Isaac Newton Blaise Pascal Your score is 0% Restart quiz Go to the Quizzes Page
