Question: Explain the theory of plate tectonics?
The theory of plate tectonics suggests that the Earth's lithosphere, or outer shell, is composed of several large, rigid plates that move and interact with one another. These plates are constantly in motion due to the underlying convective currents in the mantle, and their movement can result in geological activity such as earthquakes, volcanic eruptions, and the formation of mountain ranges. Plate boundaries can be categorized as divergent, convergent, or transform, depending on the direction of plate movement. At divergent boundaries, plates move apart from one another, allowing magma to rise and create new crust. At convergent boundaries, plates collide and can either move over, under, or alongside one another, resulting in subduction, mountain-building, or transform faulting. Transform boundaries occur when plates slide past each other in a horizontal direction. The theory of plate tectonics has revolutionized our understanding of the Earth's geology and provides a framework for studying geological phenomena such as earthquakes and volcanic activity.
