Solid Earth

Solid Earth refers to the Earth's inner and outer solid parts, including the crust, mantle, and core. It encompasses the land we walk on, the rocks beneath our feet, and the processes shaping the planet—such as plate tectonics, volcanic activity, and earthquakes. The Earth's crust is a thin, rigid outer layer that covers the more fluid, semi-solid mantle. This dynamic system drives geological changes, influencing the planet's surface features, landscapes, and the distribution of natural resources. Understanding solid Earth helps us comprehend Earth's history, its current processes, and potential natural hazards.
