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 2 / 20 What evidence did Wegener use to support his theory? All answers are correct Mountain ranges and rocks line up across continents Continents and fossils fitting together/matching-up like puzzle pieces Glacier scars and other climate evidence from temperature 3 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up. Hills islands Lakes Mountain Ranges 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 all of the landmasses on Earth. It was a supercontinent made of 3 landmasses 5 / 20 What was Alfred Wegenerś Continental Drift theory? The continents have since drifted apart to their current location All answers are correct The continents used to be joined together to form a supercontinent. Pangaea was formed around 250 million years ago 6 / 20 .......................... are long, narrow depressions on the seafloor. Plate tectonics Ocean trenches Mid-ocean ridges Glossopteris 7 / 20 The fact that similar fossils are found on both sides of the ocean is evidence of____. Seafloor spreading Magnetic reversal Oceanic drift Continental drift 8 / 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 a supercontinent that split and drifted apart to form the continents. Pangaea is one of the continents that are found nowadays. 9 / 20 What two specific continents fit together most noticeably? Africa and North America Antartica and Africa South America and Africa South America and Europe 10 / 20 Mountain ranges located on both side of the Atlantic Ocean are just separate mountain ranges. have ancient fossils and coal seams. have the same rock types, structures and ages. are the same height and width. 11 / 20 Which scientist suggested that Earth's surface used to be formed of one huge supercontinent? Alfred Wegener Isaac Newton Albert Einstein Blaise Pascal 12 / 20 Wegener's idea that Pangaea separated into continents became the continental drift .................... theory hypothesis fact law 13 / 20 According to the continental drift hypothesis, the presence of similar fossils in South America and Africa supports which scientific idea? 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. Animals easily and frequently travel from Africa to South America. 14 / 20 Originally the Continental drift theory was not well received by other scientists. Why? There was a competing theory at the time that was more believable. The scientists did not know the force responsible for moving the continents. The scientist presenting the data was unreliable. There was no data showing the continents ever moved. 15 / 20 What did Alfred Wegener observe to form his continental drift hypothesis? The coastlines of the continents match The continents are moving slowly infront of him Huge objects from space hit the Earth's surface and split the huge continent The air movement on Earth causes the supercontinent to split and drift into pieces 16 / 20 Most geologists think that the movement of Earth's tectonic plates is caused by The rotation of the Earth. Subduction. The Earth's magnetic field. Convection currents. 17 / 20 Fossil plants on different continents are evidence of Continental Drift: TRUE FALSE 18 / 20 What is the force that moves the continents? Conveyor belts Conduction Convection Radiation 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 Why did no one believe Wegener's theory? His data was wrong He didn't have evidence He didn't use the right technology to gather data He could not explain HOW the continents moved Your score is 0% Restart quiz Go to the Quizzes Page
