It is a scientific law and not a theory. Plate tectonics does not involve the movement of plates. Plate tectonics explains why continents move. Plate tectonics happened millions of years ago. 4 / 15 Which of the following happens at a transform boundary? New landmasses form when plates are stretched apart and pieces break off. Plates slide past one another and become deformed causing structural damage. Mountains form when plates are pushed together to make ridges. Nothing happens at transform boundaries, because the land does not move. 5 / 15 If the convection currents in the Earth’s mantle stopped moving, how would continental drift be affected? The Earth’s tectonic plates would begin to sink into the mantle. The movement of the Earth’s tectonic plates would speed up. The Earth’s tectonic plates would rise further above sea level. The movement of the Earth’s tectonic plates would stop. 6 / 15 Why is the theory of plate tectonics considered a theory and not a hypothesis? because there is strong evidence to support it because there are many scientists who believe it because it has not been thoroughly tested because it cannot be proven using scientific means 7 / 15 Which of the following often happens at a convergent boundary? New land is formed when plates separate and pull apart, breaking off pieces of crust. New mountains are formed when plates create ridges in their movement. Plates slide past each other, causing the rock to become deformed and structural damage to occur. Nothing happens at convergent boundaries, because the land does not move. 8 / 15 What happens at a convergent boundary? Tectonic plates move toward each other. Tectonic plates do not move. Tectonic plates move past each other. Tectonic plates move apart. 9 / 15 Which of the following is a piece of evidence supporting the theory of plate tectonics? The fossil and rock evidence on different continents indicates similar landforms. The shape of the Earth’s continents shows clues that they were once connected like pieces of a puzzle. The oceans are known to have changed position over millions of years. The Earth starts to move during earthquakes and volcanic eruptions. 10 / 15 Which of the following provided evidence for Wegener's hypothesis of continental drift? The same minerals had been found on different continents. Similar rock formations had been found on different continents. Similar fossils had been found on different continents. The continents had been pulled apart by tectonic plates at some point. 11 / 15 How did Alfred Wegener support his hypothesis of continental drift with evidence? by pointing out the fact that the continents do not match in shape by explaining how he believed that the Earth's crust was made of plates by noting the different types of plants that grow on different continents by citing similar rock formations that have been found on different continents 12 / 15 What is Pangaea? the name of the super-continent that existed millions of years ago another name for continental drift the name of a German scientist the name of an ancient fossil 13 / 15 Was Alfred Wegener’s idea that continents move a hypothesis or a theory? It was a theory because it was published and reviewed. It was a hypothesis because he was able to prove it. It was a theory because he had strong evidence. It was a hypothesis because some questions couldn't be answered. 14 / 15 What is the correct order (starting from the surface) of Earth’s layers? crust, outer core, inner core, mantle mantle, outer core, inner core, crust crust, mantle, outer core, inner core outer core, inner core, crust, mantle 15 / 15 On which layer of the Earth can tectonic plates be found? the crust the outer core the mantle the inner core Your score is 0% Restart quiz Go to the Quizzes Page
