Radiation Convection Conveyor belts Conduction 2 / 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 3 / 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 It was colder at the equator during pangea 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 4 / 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 Sea floor spreading The continents have not moved 5 / 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. Species of animals probably traveled between continents on natural rafts (such as trees destroyed in tsunamis). South America and Africa were once connected together. Land bridges once existed that connected the continents. 6 / 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 one of the continents that are found nowadays. Pangaea is a supercontinent that covered all the Earth's surface in the past. 7 / 20 What was Alfred Wegenerś Continental Drift theory? The continents have since drifted apart to their current location The continents used to be joined together to form a supercontinent. All answers are correct Pangaea was formed around 250 million years ago 8 / 20 Mountain ranges located on both side of the Atlantic Ocean are the same height and width. have ancient fossils and coal seams. are just separate mountain ranges. have the same rock types, structures and ages. 9 / 20 Wegener's idea that Pangaea separated into continents became the continental drift .................... hypothesis fact theory law 10 / 20 .......................... are long, narrow depressions on the seafloor. Glossopteris Ocean trenches Mid-ocean ridges Plate tectonics 11 / 20 The fact that similar fossils are found on both sides of the ocean is evidence of____. Oceanic drift Continental drift Magnetic reversal Seafloor spreading 12 / 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 13 / 20 Which scientist suggested that Earth's surface used to be formed of one huge supercontinent? Blaise Pascal Albert Einstein Isaac Newton Alfred Wegener 14 / 20 Most geologists think that the movement of Earth's tectonic plates is caused by Subduction. Convection currents. The rotation of the Earth. The Earth's magnetic field. 15 / 20 Fossil plants on different continents are evidence of Continental Drift: TRUE FALSE 16 / 20 What was Pangaea? It was a supercontinent, made of all of the landmasses on Earth. 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 17 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up. islands Hills Mountain Ranges Lakes 18 / 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. The scientists did not know the force responsible for moving the continents. There was a competing theory at the time that was more believable. 19 / 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 continents are moving slowly infront of him The air movement on Earth causes the supercontinent to split and drift into pieces The coastlines of the continents match 20 / 20 What two specific continents fit together most noticeably? Africa and North America Antartica and Africa South America and Europe South America and Africa Your score is 0% Restart quiz Go to the Quizzes Page
