Mountain Ranges Hills islands Lakes 2 / 20 Which statement is TRUE about Pangaea? 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. Pangaea is a continent that was covered with water in the past. 3 / 20 What is the force that moves the continents? Convection Conduction Conveyor belts Radiation 4 / 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 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. 5 / 20 Which scientist suggested that Earth's surface used to be formed of one huge supercontinent? Albert Einstein Isaac Newton Alfred Wegener Blaise Pascal 6 / 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 scientist presenting the data was unreliable. The scientists did not know the force responsible for moving the continents. There was no data showing the continents ever moved. 7 / 20 .......................... are long, narrow depressions on the seafloor. Plate tectonics Mid-ocean ridges Glossopteris Ocean trenches 8 / 20 The fact that similar fossils are found on both sides of the ocean is evidence of____. Oceanic drift Magnetic reversal Continental drift Seafloor spreading 9 / 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 a supercontinent, made of all of the landmasses on Earth. It was the name of an ancient organism 10 / 20 Mountain ranges located on both side of the Atlantic Ocean have the same rock types, structures and ages. have ancient fossils and coal seams. are just separate mountain ranges. are the same height and width. 11 / 20 What did Alfred Wegener observe to form his continental drift hypothesis? 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 The air movement on Earth causes the supercontinent to split and drift into pieces 12 / 20 What two specific continents fit together most noticeably? South America and Europe Africa and North America Antartica and Africa South America and Africa 13 / 20 Why did no one believe Wegener's theory? He could not explain HOW the continents moved His data was wrong He didn't use the right technology to gather data He didn't have evidence 14 / 20 What was Alfred Wegenerś Continental Drift theory? 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 Pangaea was formed around 250 million years ago 15 / 20 Fossil plants on different continents are evidence of Continental Drift: TRUE FALSE 16 / 20 Wegener's idea that Pangaea separated into continents became the continental drift .................... law theory fact hypothesis 17 / 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 18 / 20 According to the continental drift hypothesis, the presence of similar fossils in South America and Africa supports which scientific idea? Animals easily and frequently travel from Africa to South America. Land bridges once existed that connected the continents. Species of animals probably traveled between continents on natural rafts (such as trees destroyed in tsunamis). South America and Africa were once connected together. 19 / 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. Convection currents. Subduction. 20 / 20 What evidence did Wegener use to support his theory? Mountain ranges and rocks line up across continents Glacier scars and other climate evidence from temperature All answers are correct Continents and fossils fitting together/matching-up like puzzle pieces Your score is 0% Restart quiz Go to the Quizzes Page
