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