What are these evidence for? Sea floor spreading Africa was once in an area of the Earth that had a very cold climate Africa has always been near the equator The continents have not moved 2 / 20 What was Pangaea? 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 the name of an ancient organism It was a supercontinent made of 3 landmasses 3 / 20 .......................... are long, narrow depressions on the seafloor. Plate tectonics Glossopteris Mid-ocean ridges Ocean trenches 4 / 20 What did Alfred Wegener observe to form his continental drift hypothesis? The air movement on Earth causes the supercontinent to split and drift into pieces The coastlines of the continents match Huge objects from space hit the Earth's surface and split the huge continent The continents are moving slowly infront of him 5 / 20 What two specific continents fit together most noticeably? Africa and North America South America and Europe Antartica and Africa South America and Africa 6 / 20 Fossil plants on different continents are evidence of Continental Drift: TRUE FALSE 7 / 20 Mountain ranges located on both side of the Atlantic Ocean have the same rock types, structures and ages. have ancient fossils and coal seams. are the same height and width. are just separate mountain ranges. 8 / 20 What is the force that moves the continents? Conduction Conveyor belts Convection Radiation 9 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up. Hills Mountain Ranges Lakes islands 10 / 20 Which scientist suggested that Earth's surface used to be formed of one huge supercontinent? Alfred Wegener Isaac Newton Blaise Pascal Albert Einstein 11 / 20 Wegener's idea that Pangaea separated into continents became the continental drift .................... hypothesis theory law fact 12 / 20 Most geologists think that the movement of Earth's tectonic plates is caused by Convection currents. The Earth's magnetic field. Subduction. The rotation of the Earth. 13 / 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. 14 / 20 The fact that similar fossils are found on both sides of the ocean is evidence of____. Continental drift Magnetic reversal Seafloor spreading Oceanic drift 15 / 20 What was Alfred Wegenerś Continental Drift theory? The continents used to be joined together to form a supercontinent. Pangaea was formed around 250 million years ago All answers are correct The continents have since drifted apart to their current location 16 / 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). 17 / 20 Which statement is TRUE about Pangaea? 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 split and drifted apart to form the continents. Pangaea is a supercontinent that covered all the Earth's surface in the past. 18 / 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 Evidence of glaciers are found on continents that are in tropical regions of the earth. It was colder at the equator during pangea Climate change caused the earth's continents to move 19 / 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 20 / 20 What evidence did Wegener use to support his theory? Glacier scars and other climate evidence from temperature All answers are correct Mountain ranges and rocks line up across continents Continents and fossils fitting together/matching-up like puzzle pieces Your score is 0% Restart quiz Go to the Quizzes Page
