He didn't have evidence He could not explain HOW the continents moved His data was wrong He didn't use the right technology to gather data 3 / 20 What evidence from the climate supports the idea that the continents were once joined and then drifted apart? Choose all that apply. 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 It was colder at the equator during pangea Climate change caused the earth's continents to move 4 / 20 What was Pangaea? 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 3 landmasses It was a supercontinent, made of all of the landmasses on Earth. 5 / 20 What is the force that moves the continents? Radiation Conduction Conveyor belts Convection 6 / 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 Pangaea was formed around 250 million years ago All answers are correct 7 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up. Hills Lakes islands Mountain Ranges 8 / 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. There was a competing theory at the time that was more believable. The scientists did not know the force responsible for moving the continents. 9 / 20 .......................... are long, narrow depressions on the seafloor. Ocean trenches Mid-ocean ridges Glossopteris Plate tectonics 10 / 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. South America and Africa were once connected together. 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). 11 / 20 Mountain ranges located on both side of the Atlantic Ocean have ancient fossils and coal seams. are the same height and width. are just separate mountain ranges. have the same rock types, structures and ages. 12 / 20 Most geologists think that the movement of Earth's tectonic plates is caused by Subduction. The Earth's magnetic field. Convection currents. The rotation of the Earth. 13 / 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 continents are moving slowly infront of him The coastlines of the continents match Huge objects from space hit the Earth's surface and split the huge continent 14 / 20 Fossil plants on different continents are evidence of Continental Drift: TRUE FALSE 15 / 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 Africa has always been near the equator The continents have not moved 16 / 20 Which scientist suggested that Earth's surface used to be formed of one huge supercontinent? Blaise Pascal Albert Einstein Isaac Newton Alfred Wegener 17 / 20 What two specific continents fit together most noticeably? South America and Europe Africa and North America Antartica and Africa South America and Africa 18 / 20 The fact that similar fossils are found on both sides of the ocean is evidence of____. Seafloor spreading Oceanic drift Continental drift Magnetic reversal 19 / 20 What evidence did Wegener use to support his theory? Continents and fossils fitting together/matching-up like puzzle pieces Mountain ranges and rocks line up across continents All answers are correct Glacier scars and other climate evidence from temperature 20 / 20 Which statement is TRUE about Pangaea? 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. Pangaea is a supercontinent that split and drifted apart to form the continents. Your score is 0% Restart quiz Go to the Quizzes Page
