Seafloor spreading Continental drift Magnetic reversal Oceanic drift 2 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up. Hills Mountain Ranges islands Lakes 3 / 20 What was Alfred Wegenerś Continental Drift theory? Pangaea was formed around 250 million years ago All answers are correct The continents used to be joined together to form a supercontinent. The continents have since drifted apart to their current location 4 / 20 Most geologists think that the movement of Earth's tectonic plates is caused by The Earth's magnetic field. The rotation of the Earth. Subduction. Convection currents. 5 / 20 .......................... are long, narrow depressions on the seafloor. Glossopteris Ocean trenches Plate tectonics Mid-ocean ridges 6 / 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 7 / 20 Wegener's idea that Pangaea separated into continents became the continental drift .................... fact theory hypothesis law 8 / 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 Sea floor spreading The continents have not moved Africa has always been near the equator 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 could not explain HOW the continents moved He didn't have evidence 10 / 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. 11 / 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 The coastlines of the continents match Huge objects from space hit the Earth's surface and split the huge continent The continents are moving slowly infront of him 12 / 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 the same height and width. are just separate mountain ranges. 13 / 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 scientists did not know the force responsible for moving the continents. The scientist presenting the data was unreliable. 14 / 20 Fossil plants on different continents are evidence of Continental Drift: FALSE TRUE 15 / 20 What two specific continents fit together most noticeably? South America and Europe Antartica and Africa Africa and North America South America and Africa 16 / 20 What evidence from the climate supports the idea that the continents were once joined and then drifted apart? Choose all that apply. It was colder at the equator during pangea Climate change caused the earth's continents to move 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. 17 / 20 Which scientist suggested that Earth's surface used to be formed of one huge supercontinent? Albert Einstein Isaac Newton Blaise Pascal Alfred Wegener 18 / 20 Which statement is TRUE about Pangaea? Pangaea is a continent that was covered with water in the past. 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 supercontinent that split and drifted apart to form the continents. 19 / 20 According to the continental drift hypothesis, the presence of similar fossils in South America and Africa supports which scientific idea? 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. 20 / 20 What is the force that moves the continents? Convection Radiation Conduction Conveyor belts Your score is 0% Restart quiz Go to the Quizzes Page
