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