What is plate tectonics?
Q: What is plate tectonics?
A: Plate tectonics is a theory of geology that explains the movement of the Earth's lithosphere, which is the Earth's crust and the upper part of the mantle.
Q: What is the lithosphere?
A: The lithosphere is the Earth's crust and the upper part of the mantle.
Q: How is the lithosphere divided?
A: The lithosphere is divided into plates, some of which are very large and can be entire continents.
Q: What is the source of energy driving plate tectonics?
A: Heat from the mantle is the source of energy driving plate tectonics.
Q: Is the mechanism driving plate tectonics fully understood?
A: No, exactly how the mechanism driving plate tectonics works is still a matter of debate.
Q: What is the definition of the mantle?
A: The mantle is the layer of the Earth between the crust and the core, and is made up of mostly solid rock.
Q: Does plate tectonics only affect the Earth's crust?
A: No, plate tectonics affects the Earth's crust and the upper part of the mantle, as this is the lithosphere.
