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 one of the continents that are found nowadays. Pangaea is a continent that was covered with water in the past. 2 / 20 What was Alfred Wegenerś Continental Drift theory? The continents have since drifted apart to their current location The continents used to be joined together to form a supercontinent. All answers are correct Pangaea was formed around 250 million years ago 3 / 20 Originally the Continental drift theory was not well received by other scientists. Why? 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. There was a competing theory at the time that was more believable. 4 / 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 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 coastlines of the continents match The continents are moving slowly infront of him 6 / 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). Land bridges once existed that connected the continents. South America and Africa were once connected together. Animals easily and frequently travel from Africa to South America. 7 / 20 What is the force that moves the continents? Convection Conveyor belts Radiation Conduction 8 / 20 What was Pangaea? It was the name of an ancient organism It was a supercontinent made of 3 landmasses 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. 9 / 20 .......................... are long, narrow depressions on the seafloor. Glossopteris Mid-ocean ridges Plate tectonics Ocean trenches 10 / 20 Fossil plants on different continents are evidence of Continental Drift: FALSE TRUE 11 / 20 What evidence from the climate supports the idea that the continents were once joined and then drifted apart? Choose all that apply. Climate change caused the earth's continents to move It was colder at the equator during pangea Remains of plants and animals are found in climates which they could not have survived Evidence of glaciers are found on continents that are in tropical regions of the earth. 12 / 20 What evidence did Wegener use to support his theory? Glacier scars and other climate evidence from temperature Continents and fossils fitting together/matching-up like puzzle pieces All answers are correct Mountain ranges and rocks line up across continents 13 / 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 Sea floor spreading Africa has always been near the equator 14 / 20 Mountain ranges located on both side of the Atlantic Ocean have ancient fossils and coal seams. have the same rock types, structures and ages. are just separate mountain ranges. are the same height and width. 15 / 20 Most geologists think that the movement of Earth's tectonic plates is caused by The rotation of the Earth. Convection currents. The Earth's magnetic field. Subduction. 16 / 20 Which scientist suggested that Earth's surface used to be formed of one huge supercontinent? Alfred Wegener Blaise Pascal Isaac Newton Albert Einstein 17 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up. Mountain Ranges Hills islands Lakes 18 / 20 What two specific continents fit together most noticeably? Africa and North America South America and Europe Antartica and Africa South America and Africa 19 / 20 Wegener's idea that Pangaea separated into continents became the continental drift .................... fact hypothesis theory law 20 / 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 Your score is 0% Restart quiz Go to the Quizzes Page
