The Earth is a master of recycling; while the continental crust can survive for billions of years, the oceanic crust is a dynamic, ever-refreshing skin destined to return to the mantle.

Earth is composed of three main layers: the crust, the mantle, and the core. The crust is the outermost solid shell where we live, followed by the thick, semi-solid mantle. At the center lies the core, which is divided into liquid and solid sections. Understanding these layers is fundamental to geology as it explains how heat and materials move within our planet.
The Earth's crust is not a single solid piece but is divided into several large and small tectonic plates. These plates sit atop the mantle and move very slowly over millions of years. This process, known as plate tectonics, is responsible for shaping the Earth's surface, creating mountains, and causing seismic activity as the plates interact at their boundaries.
Plate tectonics is a central concept in geology because it explains the dynamic nature of our planet. As tectonic plates move over the mantle, they shift continents and change the layout of ocean basins. This slow but constant movement is the driving force behind most geological changes, influencing everything from volcanic eruptions to the long-term evolution of Earth's physical landscape.
