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 It was colder at the equator during pangea Climate change caused the earth's continents to move 2 / 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 Glacier scars and other climate evidence from temperature All answers are correct 3 / 20 Why did no one believe Wegener's theory? He didn't have evidence His data was wrong He could not explain HOW the continents moved He didn't use the right technology to gather data 4 / 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 5 / 20 Originally the Continental drift theory was not well received by other scientists. Why? 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. The scientists did not know the force responsible for moving the continents. 6 / 20 This is a picture of glacier scars found in Africa. 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 7 / 20 Which statement is TRUE about Pangaea? 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. Pangaea is one of the continents that are found nowadays. Pangaea is a supercontinent that covered all the Earth's surface in the past. 8 / 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 9 / 20 Which scientist suggested that Earth's surface used to be formed of one huge supercontinent? Blaise Pascal Albert Einstein Isaac Newton Alfred Wegener 10 / 20 According to the continental drift hypothesis, the presence of similar fossils in South America and Africa supports which scientific idea? Species of animals probably traveled between continents on natural rafts (such as trees destroyed in tsunamis). Land bridges once existed that connected the continents. Animals easily and frequently travel from Africa to South America. South America and Africa were once connected together. 11 / 20 Wegener's idea that Pangaea separated into continents became the continental drift .................... fact hypothesis theory law 12 / 20 Most geologists think that the movement of Earth's tectonic plates is caused by The rotation of the Earth. Convection currents. The Earth's magnetic field. Subduction. 13 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up. Mountain Ranges Lakes Hills islands 14 / 20 Mountain ranges located on both side of the Atlantic Ocean have ancient fossils and coal seams. are the same height and width. are just separate mountain ranges. have the same rock types, structures and ages. 15 / 20 What is the force that moves the continents? Convection Radiation Conveyor belts Conduction 16 / 20 .......................... are long, narrow depressions on the seafloor. Ocean trenches Mid-ocean ridges Plate tectonics Glossopteris 17 / 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. All answers are correct The continents have since drifted apart to their current location 18 / 20 What two specific continents fit together most noticeably? South America and Europe Africa and North America South America and Africa Antartica and Africa 19 / 20 Fossil plants on different continents are evidence of Continental Drift: TRUE FALSE 20 / 20 What was Pangaea? It was a supercontinent, made of all of the landmasses on Earth. 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.
