Answer:
According to the theory of plate tectonics, A. the lithosphere is divided into plates.
Step-by-step explanation:
According to the theory of plate tectonics, A. the lithosphere is divided into plates.
The theory of plate tectonics explains the movement of the Earth's lithosphere, which is the rigid outer layer that includes the crust and the upper part of the mantle. According to the theory, the lithosphere is divided into several large plates, which move around and interact with each other at their boundaries. The movement of the plates is driven by convection currents in the underlying asthenosphere, which is a weaker and more ductile layer of the mantle. As the plates move, they can interact with each other in various ways, such as by colliding, sliding past each other, or pulling apart, leading to the formation of mountains, ocean basins, and other geological features.
It is important to note that the asthenosphere is not divided into plates; rather, it is the lithosphere that is divided into plates. Additionally, the asthenosphere is not strong and rigid, but rather weak and ductile, which allows it to flow and convect, driving the movement of the overlying lithospheric plates.
