Bill Nye: Earth's Crust Questions and Answers | Latest Version | 2024/2025 | Graded A+ What is the Earth’s crust? The Earth’s crust is the outermost solid layer of the Earth, composed of rock and minerals. What are the two types of Earth’s crust? The two types of Earth’s crust are the continental crust and the oceanic crust. What is the difference between the continental crust and the oceanic crust? The continental crust is thicker and less dense, while the oceanic crust is thinner and more dense. How thick is the Earth’s crust on average? The Earth's crust is about 5-70 kilometers thick, with oceanic crust being thinner and continental crust being thicker. What is the Earth’s crust composed of? 2 The Earth’s crust is composed mainly of rocks like basalt and granite, as well as minerals such as quartz and feldspar. What is the main force responsible for shaping the Earth’s crust? The main force responsible for shaping the Earth’s crust is plate tectonics, which involves the movement of large plates that form the Earth's surface. What are tectonic plates? Tectonic plates are large, rigid pieces of the Earth's crust that move over the underlying mantle. What happens when tectonic plates collide? When tectonic plates collide, it can create mountains, earthquakes, or volcanic activity. How do tectonic plates move? Tectonic plates move because of the flow of molten rock in the Earth’s mantle, which causes the plates to shift, collide, or pull apart. What is a fault line? 3 A fault line is a crack or fracture in the Earth's crust where tectonic plates meet and can move past each other. What is the Ring of Fire? The Ring of Fire is a region around the Pacific Ocean where many earthquakes and volcanic eruptions occur due to active tectonic plate boundaries. What is an earthquake? An earthquake is the shaking of the Earth’s surface caused by the movement of tectonic plates along a fault line. What is a volcano?
