Why? The scientist presenting the data was unreliable. There was no data showing the continents ever moved. The scientists did not know the force responsible for moving the continents. There was a competing theory at the time that was more believable. 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. 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). 3 / 20 Wegener's idea that Pangaea separated into continents became the continental drift .................... fact hypothesis law theory 4 / 20 What was Pangaea? It was a supercontinent, made of all of the landmasses on Earth. 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 3 landmasses 5 / 20 What was Alfred Wegenerś Continental Drift theory? Pangaea was formed around 250 million years ago All answers are correct The continents used to be joined together to form a supercontinent. The continents have since drifted apart to their current location 6 / 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 7 / 20 Why did no one believe Wegener's theory? He didn't use the right technology to gather data He could not explain HOW the continents moved He didn't have evidence His data was wrong 8 / 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 continent that was covered with water in the past. Pangaea is a supercontinent that split and drifted apart to form the continents. 9 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up. islands Mountain Ranges Lakes Hills 10 / 20 Most geologists think that the movement of Earth's tectonic plates is caused by The rotation of the Earth. The Earth's magnetic field. Convection currents. Subduction. 11 / 20 What is the force that moves the continents? Conduction Convection Radiation Conveyor belts 12 / 20 .......................... are long, narrow depressions on the seafloor. Ocean trenches Plate tectonics Glossopteris Mid-ocean ridges 13 / 20 What evidence from the climate supports the idea that the continents were once joined and then drifted apart? Choose all that apply. Remains of plants and animals are found in climates which they could not have survived Climate change caused the earth's continents to move Evidence of glaciers are found on continents that are in tropical regions of the earth. It was colder at the equator during pangea 14 / 20 What evidence did Wegener use to support his theory? All answers are correct Continents and fossils fitting together/matching-up like puzzle pieces Glacier scars and other climate evidence from temperature Mountain ranges and rocks line up across continents 15 / 20 Fossil plants on different continents are evidence of Continental Drift: TRUE FALSE 16 / 20 What did Alfred Wegener observe to form his continental drift hypothesis? The continents are moving slowly infront of him The coastlines of the continents match The air movement on Earth causes the supercontinent to split and drift into pieces Huge objects from space hit the Earth's surface and split the huge continent 17 / 20 Which scientist suggested that Earth's surface used to be formed of one huge supercontinent? Blaise Pascal Alfred Wegener Albert Einstein Isaac Newton 18 / 20 Mountain ranges located on both side of the Atlantic Ocean have ancient fossils and coal seams. have the same rock types, structures and ages. are just separate mountain ranges. are the same height and width. 19 / 20 This is a picture of glacier scars found in Africa. What are these evidence for? The continents have not moved Africa has always been near the equator Sea floor spreading Africa was once in an area of the Earth that had a very cold climate 20 / 20 What two specific continents fit together most noticeably? Antartica and Africa Africa and North America South America and Europe South America and Africa Your score is 0% Restart quiz Go to the Quizzes Page
