Plate tectonics happened millions of years ago. Plate tectonics explains why continents move. Plate tectonics does not involve the movement of plates. It is a scientific law and not a theory. 3 / 15 Which of the following are actions of moving tectonic plates? plates slide past each other, move toward each other, and move away from one another they only move towards each other they only slide past each other they only move away from each other 4 / 15 Was Alfred Wegener’s idea that continents move a hypothesis or a theory? It was a hypothesis because some questions couldn't be answered. 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. 5 / 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 stop. The Earth’s tectonic plates would rise further above sea level. The Earth’s tectonic plates would begin to sink into the mantle. The movement of the Earth’s tectonic plates would speed up. 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 is strong evidence to support it because there are many scientists who believe it because it cannot be proven using scientific means 7 / 15 What happens at a convergent boundary? Tectonic plates move apart. Tectonic plates do not move. Tectonic plates move past each other. Tectonic plates move toward each other. 8 / 15 Which of the following provided evidence for Wegener's hypothesis of continental drift? The same minerals 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. Similar rock formations had been found on different continents. 9 / 15 On which layer of the Earth can tectonic plates be found? the crust the inner core the outer core the mantle 10 / 15 Which of the following often happens at a convergent boundary? Nothing happens at convergent boundaries, because the land does not move. 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. 11 / 15 What is Pangaea? the name of an ancient fossil the name of a German scientist the name of the super-continent that existed millions of years ago another name for continental drift 12 / 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 citing similar rock formations that have been found on different continents by noting the different types of plants that grow on different continents 13 / 15 Which of the following is a piece of evidence supporting the theory of plate tectonics? The Earth starts to move during earthquakes and volcanic eruptions. 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. 14 / 15 The process by which the ocean floor sinks beneath a deep-ocean trench and back into the mantle is known as _______ subduction. convection. continental drift. conduction. 15 / 15 Which of the following happens at a transform boundary? Mountains form when plates are pushed together to make ridges. Nothing happens at transform boundaries, because the land does not move. Plates slide past one another and become deformed causing structural damage. New landmasses form when plates are stretched apart and pieces break off.
