The Earth (as a concept)

The Earth is the third planet from the Sun in our solar system, known for supporting life. It has a unique atmosphere that provides oxygen and protects us from harmful space radiation. Earth's surface consists of land, water, and ice, with diverse ecosystems home to countless species. It has a core, mantle, and crust, and experiences geological processes like earthquakes and volcanic eruptions. The planet completes one rotation on its axis roughly every 24 hours, leading to day and night, and orbits the Sun in about 365 days, defining our year. Earth's climate and natural resources are vital for human existence.
