Water on Earth primarily originates from two sources: volcanic outgassing during the planet's formation and the accumulation of water delivered by comets and asteroids. Over billions of years, water vapor released from volcanic activity condensed to form oceans. Additionally, Earth's unique position in the solar system allows it to maintain liquid water, a crucial factor for sustaining life. Today, the water cycle continuously redistributes water through evaporation, condensation, precipitation, and runoff.
