Glacier scars and other climate evidence from temperature All answers are correct Continents and fossils fitting together/matching-up like puzzle pieces Mountain ranges and rocks line up across continents 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 Fossil plants on different continents are evidence of Continental Drift: TRUE FALSE 5 / 20 What two specific continents fit together most noticeably? Africa and North America Antartica and Africa South America and Africa South America and Europe 6 / 20 The fact that similar fossils are found on both sides of the ocean is evidence of____. Oceanic drift Continental drift Seafloor spreading Magnetic reversal 7 / 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. The scientist presenting the data was unreliable. There was no data showing the continents ever moved. There was a competing theory at the time that was more believable. 8 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up. islands Hills Mountain Ranges Lakes 9 / 20 Why did no one believe Wegener's theory? He didn't use the right technology to gather data His data was wrong He could not explain HOW the continents moved He didn't have evidence 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. Species of animals probably traveled between continents on natural rafts (such as trees destroyed in tsunamis). South America and Africa were once connected together. Animals easily and frequently travel from Africa to South America. 11 / 20 What was Alfred Wegenerś Continental Drift theory? Pangaea was formed around 250 million years ago The continents used to be joined together to form a supercontinent. The continents have since drifted apart to their current location All answers are correct 12 / 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 13 / 20 Most geologists think that the movement of Earth's tectonic plates is caused by Subduction. Convection currents. The Earth's magnetic field. The rotation of the Earth. 14 / 20 Mountain ranges located on both side of the Atlantic Ocean have the same rock types, structures and ages. are just separate mountain ranges. are the same height and width. have ancient fossils and coal seams. 15 / 20 .......................... are long, narrow depressions on the seafloor. Plate tectonics Glossopteris Mid-ocean ridges Ocean trenches 16 / 20 Which scientist suggested that Earth's surface used to be formed of one huge supercontinent? Isaac Newton Alfred Wegener Albert Einstein Blaise Pascal 17 / 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. 18 / 20 What did Alfred Wegener observe to form his continental drift hypothesis? 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 The continents are moving slowly infront of him 19 / 20 What was Pangaea? It was a supercontinent made of 3 landmasses 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 all of the landmasses on Earth. 20 / 20 What is the force that moves the continents? Conveyor belts Radiation Convection Conduction Your score is 0% Restart quiz Go to the Quizzes Page
