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 3 / 20 .......................... are long, narrow depressions on the seafloor. Glossopteris Mid-ocean ridges Plate tectonics Ocean trenches 4 / 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 a supercontinent that covered all the Earth's surface in the past. Pangaea is one of the continents that are found nowadays. 5 / 20 Fossil plants on different continents are evidence of Continental Drift: FALSE TRUE 6 / 20 Why did no one believe Wegener's theory? He could not explain HOW the continents moved His data was wrong He didn't use the right technology to gather data He didn't have evidence 7 / 20 When Wegener looked at maps he noticed Africa and South America ____________ lined up. Mountain Ranges Hills islands Lakes 8 / 20 What was Alfred Wegenerś Continental Drift theory? All answers are correct Pangaea was formed around 250 million years ago The continents have since drifted apart to their current location The continents used to be joined together to form a supercontinent. 9 / 20 Wegener's idea that Pangaea separated into continents became the continental drift .................... law theory fact hypothesis 10 / 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 air movement on Earth causes the supercontinent to split and drift into pieces The coastlines of the continents match 11 / 20 What evidence did Wegener use to support his theory? Continents and fossils fitting together/matching-up like puzzle pieces Glacier scars and other climate evidence from temperature Mountain ranges and rocks line up across continents All answers are correct 12 / 20 The fact that similar fossils are found on both sides of the ocean is evidence of____. Seafloor spreading Oceanic drift Magnetic reversal Continental drift 13 / 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 Remains of plants and animals are found in climates which they could not have survived It was colder at the equator during pangea Evidence of glaciers are found on continents that are in tropical regions of the earth. 14 / 20 Which scientist suggested that Earth's surface used to be formed of one huge supercontinent? Isaac Newton Albert Einstein Blaise Pascal Alfred Wegener 15 / 20 What was Pangaea? 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 It was 2 separate landmasses, one on the Northern Hemisphere and one on the Southern Hemisphere. 16 / 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. The scientists did not know the force responsible for moving the continents. There was a competing theory at the time that was more believable. 17 / 20 Most geologists think that the movement of Earth's tectonic plates is caused by Convection currents. The rotation of the Earth. The Earth's magnetic field. Subduction. 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 What is the force that moves the continents? Convection Conduction Conveyor belts Radiation 20 / 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. Land bridges once existed that connected the continents. Species of animals probably traveled between continents on natural rafts (such as trees destroyed in tsunamis). Animals easily and frequently travel from Africa to South America.
