The tectonic cycle refers to the continuous movement and recycling of the Earth's lithosphere, which is divided into large plates known as tectonic plates. These plates float on the semi-fluid layer of the mantle and interact at their boundaries, leading to geological activities such as earthquakes, volcanic eruptions, and the formation of mountain ranges. As tectonic plates move, they can converge, diverge, or slide past one another. This movement is driven by forces such as mantle convection and gravity. Over millions of years, the tectonic cycle shapes the Earth's surface, creating new landforms and altering existing ones, contributing to the dynamic nature of our planet.
