What are these evidence for? The continents have not moved 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 2 / 20 .......................... are long, narrow depressions on the seafloor. Mid-ocean ridges Plate tectonics Glossopteris Ocean trenches 3 / 20 Which statement is TRUE about Pangaea? Pangaea is a supercontinent that covered all the Earth's surface 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 continent that was covered with water in the past. 4 / 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. Climate change caused the earth's continents to move It was colder at the equator during pangea 5 / 20 What was Alfred Wegenerś Continental Drift theory? The continents have since drifted apart to their current location Pangaea was formed around 250 million years ago All answers are correct The continents used to be joined together to form a supercontinent. 6 / 20 What was Pangaea? It was 2 separate landmasses, one on the Northern Hemisphere and one on the Southern Hemisphere. It was a supercontinent made of 3 landmasses It was the name of an ancient organism It was a supercontinent, made of all of the landmasses on Earth. 7 / 20 Wegener's idea that Pangaea separated into continents became the continental drift .................... theory law hypothesis fact 8 / 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. 9 / 20 Fossil plants on different continents are evidence of Continental Drift: TRUE FALSE 10 / 20 What evidence did Wegener use to support his theory? Continents and fossils fitting together/matching-up like puzzle pieces Mountain ranges and rocks line up across continents All answers are correct Glacier scars and other climate evidence from temperature 11 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up. Lakes Hills Mountain Ranges islands 12 / 20 What two specific continents fit together most noticeably? South America and Africa Africa and North America Antartica and Africa South America and Europe 13 / 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. 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. 14 / 20 The fact that similar fossils are found on both sides of the ocean is evidence of____. Seafloor spreading Continental drift Magnetic reversal Oceanic drift 15 / 20 Mountain ranges located on both side of the Atlantic Ocean have ancient fossils and coal seams. are just separate mountain ranges. are the same height and width. have the same rock types, structures and ages. 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 What is the force that moves the continents? Conveyor belts Convection Conduction Radiation 18 / 20 Which scientist suggested that Earth's surface used to be formed of one huge supercontinent? Alfred Wegener Blaise Pascal Isaac Newton Albert Einstein 19 / 20 What did Alfred Wegener observe to form his continental drift hypothesis? Huge objects from space hit the Earth's surface and split the huge continent 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 20 / 20 Why did no one believe Wegener's theory? He didn't have evidence He didn't use the right technology to gather data He could not explain HOW the continents moved His data was wrong Your score is 0% Restart quiz Go to the Quizzes Page
