Animals easily and frequently travel from Africa to South America. 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). 2 / 20 Most geologists think that the movement of Earth's tectonic plates is caused by The Earth's magnetic field. Convection currents. The rotation of the Earth. Subduction. 3 / 20 .......................... are long, narrow depressions on the seafloor. Glossopteris Plate tectonics Ocean trenches Mid-ocean ridges 4 / 20 Why did no one believe Wegener's theory? He didn't use the right technology to gather data His data was wrong He didn't have evidence He could not explain HOW the continents moved 5 / 20 What evidence from the climate supports the idea that the continents were once joined and then drifted apart? Choose all that apply. 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 Climate change caused the earth's continents to move It was colder at the equator during pangea 6 / 20 What two specific continents fit together most noticeably? Antartica and Africa South America and Africa Africa and North America South America and Europe 7 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up. Mountain Ranges Lakes islands Hills 8 / 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. 9 / 20 This is a picture of glacier scars found in Africa. What are these evidence for? Africa was once in an area of the Earth that had a very cold climate Sea floor spreading Africa has always been near the equator The continents have not moved 10 / 20 What was Pangaea? 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. It was a supercontinent made of 3 landmasses 11 / 20 What evidence did Wegener use to support his theory? Mountain ranges and rocks line up across continents Continents and fossils fitting together/matching-up like puzzle pieces All answers are correct Glacier scars and other climate evidence from temperature 12 / 20 Wegener's idea that Pangaea separated into continents became the continental drift .................... hypothesis theory law fact 13 / 20 Which statement is TRUE about Pangaea? 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. Pangaea is one of the continents that are found nowadays. 14 / 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 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 15 / 20 Which scientist suggested that Earth's surface used to be formed of one huge supercontinent? Isaac Newton Blaise Pascal Alfred Wegener Albert Einstein 16 / 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 17 / 20 Fossil plants on different continents are evidence of Continental Drift: FALSE TRUE 18 / 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. 19 / 20 What was Alfred Wegenerś Continental Drift theory? The continents used to be joined together to form a supercontinent. All answers are correct Pangaea was formed around 250 million years ago The continents have since drifted apart to their current location 20 / 20 What is the force that moves the continents? Convection Radiation Conduction Conveyor belts Your score is 0% Restart quiz Go to the Quizzes Page
