Isaac Newton Blaise Pascal Alfred Wegener Albert Einstein 2 / 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. Land bridges once existed that connected the continents. Animals easily and frequently travel from Africa to South America. Species of animals probably traveled between continents on natural rafts (such as trees destroyed in tsunamis). 3 / 20 Mountain ranges located on both side of the Atlantic Ocean are the same height and width. are just separate mountain ranges. have ancient fossils and coal seams. have the same rock types, structures and ages. 4 / 20 What was Pangaea? It was a supercontinent made of 3 landmasses It was the name of an ancient organism 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. 5 / 20 What two specific continents fit together most noticeably? Africa and North America South America and Europe Antartica and Africa South America and Africa 6 / 20 What evidence did Wegener use to support his theory? Continents and fossils fitting together/matching-up like puzzle pieces All answers are correct Glacier scars and other climate evidence from temperature Mountain ranges and rocks line up across continents 7 / 20 Wegener's idea that Pangaea separated into continents became the continental drift .................... hypothesis fact theory law 8 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up. Hills Mountain Ranges islands Lakes 9 / 20 What was Alfred Wegenerś Continental Drift theory? All answers are correct The continents have since drifted apart to their current location The continents used to be joined together to form a supercontinent. Pangaea was formed around 250 million years ago 10 / 20 Originally the Continental drift theory was not well received by other scientists. Why? There was no data showing the continents ever moved. 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. 11 / 20 The fact that similar fossils are found on both sides of the ocean is evidence of____. Magnetic reversal Continental drift Oceanic drift Seafloor spreading 12 / 20 .......................... are long, narrow depressions on the seafloor. Glossopteris Plate tectonics Mid-ocean ridges Ocean trenches 13 / 20 Fossil plants on different continents are evidence of Continental Drift: TRUE FALSE 14 / 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 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. Climate change caused the earth's continents to move 15 / 20 Most geologists think that the movement of Earth's tectonic plates is caused by Convection currents. The rotation of the Earth. Subduction. The Earth's magnetic field. 16 / 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 air movement on Earth causes the supercontinent to split and drift into pieces The continents are moving slowly infront of him 17 / 20 Why did no one believe Wegener's theory? He could not explain HOW the continents moved He didn't have evidence His data was wrong He didn't use the right technology to gather data 18 / 20 What is the force that moves the continents? Convection Conduction Radiation Conveyor belts 19 / 20 This is a picture of glacier scars found in Africa. What are these evidence for? Africa has always been near the equator Africa was once in an area of the Earth that had a very cold climate The continents have not moved Sea floor spreading 20 / 20 Which statement is TRUE about Pangaea? Pangaea is a supercontinent that split and drifted apart to form the continents. Pangaea is a continent that was covered with water in the past. Pangaea is a supercontinent that covered all the Earth's surface in the past. Pangaea is one of the continents that are found nowadays. Your score is 0% Restart quiz Go to the Quizzes Page
