Continental drift Magnetic reversal Seafloor spreading Oceanic drift 2 / 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 Evidence of glaciers are found on continents that are in tropical regions of the earth. Remains of plants and animals are found in climates which they could not have survived 3 / 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 split and drifted apart to form the continents. Pangaea is a supercontinent that covered all the Earth's surface in the past. 4 / 20 Wegener's idea that Pangaea separated into continents became the continental drift .................... theory hypothesis law fact 5 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up. islands Lakes Hills Mountain Ranges 6 / 20 What was Alfred Wegenerś Continental Drift theory? The continents have since drifted apart to their current location All answers are correct Pangaea was formed around 250 million years ago The continents used to be joined together to form a supercontinent. 7 / 20 This is a picture of glacier scars found in Africa. What are these evidence for? Sea floor spreading The continents have not moved Africa has always been near the equator Africa was once in an area of the Earth that had a very cold climate 8 / 20 What was Pangaea? It was a supercontinent made of 3 landmasses It was the name of an ancient organism 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 Fossil plants on different continents are evidence of Continental Drift: TRUE FALSE 10 / 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. 11 / 20 Why did no one believe Wegener's theory? He didn't use the right technology to gather data He didn't have evidence He could not explain HOW the continents moved His data was wrong 12 / 20 .......................... are long, narrow depressions on the seafloor. Ocean trenches Glossopteris Plate tectonics Mid-ocean ridges 13 / 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). 14 / 20 What two specific continents fit together most noticeably? South America and Europe Africa and North America Antartica and Africa South America and Africa 15 / 20 Mountain ranges located on both side of the Atlantic Ocean have the same rock types, structures and ages. are the same height and width. have ancient fossils and coal seams. are just separate mountain ranges. 16 / 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. 17 / 20 Which scientist suggested that Earth's surface used to be formed of one huge supercontinent? Albert Einstein Blaise Pascal Alfred Wegener Isaac Newton 18 / 20 What is the force that moves the continents? Convection Radiation Conduction Conveyor belts 19 / 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 20 / 20 What evidence did Wegener use to support his theory? Continents and fossils fitting together/matching-up like puzzle pieces Glacier scars and other climate evidence from temperature Mountain ranges and rocks line up across continents All answers are correct Your score is 0% Restart quiz Go to the Quizzes Page
