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