The Structure of the World

The structure of the world comprises matter and energy organized into atoms and molecules, which form everything around us. Earth’s layers include the crust, mantle, outer core, and inner core, each differing in composition and state. The atmosphere surrounds the planet, affecting climate and weather. On a larger scale, the universe contains billions of galaxies, each filled with stars, planets, and other celestial objects, all governed by physical laws like gravity. This interconnected structure—from microscopic atoms to vast cosmic systems—shapes the physical reality we experience every day.
