Which statement best explains the theory of plate tectonics?(1 point)

Earth’s mantle is made of rock plates that move across the crust.
Earth’s crust is formed by the magma that rises in the mantle.
Earth’s core consists of rock plates that float on top of the mantle.
Earth’s crust is composed of rock plates that float on top of the mantle.

The statement that best explains the theory of plate tectonics is: "Earth’s crust is composed of rock plates that float on top of the mantle."

The correct answer is: "Earth’s crust is composed of rock plates that float on top of the mantle."

The theory of plate tectonics explains how the Earth's lithosphere, which consists of the crust and the upper part of the mantle, is divided into several large and small plates that are constantly moving. These plates "float" on top of the semi-fluid asthenosphere beneath them. The movement of these plates has a significant impact on the Earth's geology, including the formation of mountains, earthquakes, and volcanic activity. The theory helps explain various geological phenomena and provides a framework for understanding the Earth's dynamic nature.
