Oceanic drift Seafloor spreading Magnetic reversal Continental drift 2 / 20 Wegener's idea that Pangaea separated into continents became the continental drift .................... theory hypothesis law fact 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 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 It was colder at the equator during pangea 4 / 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. South America and Africa were once connected together. Animals easily and frequently travel from Africa to South America. Species of animals probably traveled between continents on natural rafts (such as trees destroyed in tsunamis). 5 / 20 Which scientist suggested that Earth's surface used to be formed of one huge supercontinent? Alfred Wegener Isaac Newton Albert Einstein Blaise Pascal 6 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up. Mountain Ranges Lakes Hills islands 7 / 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 8 / 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 9 / 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 10 / 20 What two specific continents fit together most noticeably? Africa and North America Antartica and Africa South America and Europe South America and Africa 11 / 20 Fossil plants on different continents are evidence of Continental Drift: FALSE TRUE 12 / 20 What is the force that moves the continents? Radiation Convection Conduction Conveyor belts 13 / 20 Most geologists think that the movement of Earth's tectonic plates is caused by Convection currents. The Earth's magnetic field. The rotation of the Earth. Subduction. 14 / 20 Originally the Continental drift theory was not well received by other scientists. Why? There was no data showing the continents ever moved. There was a competing theory at the time that was more believable. The scientist presenting the data was unreliable. The scientists did not know the force responsible for moving the continents. 15 / 20 Why did no one believe Wegener's theory? His data was wrong He could not explain HOW the continents moved He didn't have evidence He didn't use the right technology to gather data 16 / 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 all of the landmasses on Earth. It was the name of an ancient organism It was a supercontinent made of 3 landmasses 17 / 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. 18 / 20 .......................... are long, narrow depressions on the seafloor. Glossopteris Ocean trenches Plate tectonics Mid-ocean ridges 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 air movement on Earth causes the supercontinent to split and drift into pieces The continents are moving slowly infront of him The coastlines of the continents match 20 / 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.
