The video explains the water cycle, also known as the hydrologic cycle, which is essential for life on Earth. It describes how water moves from the Earth's surface to the atmosphere and back, through processes like evaporation, condensation, and precipitation. The cycle is crucial for weather patterns and the recycling of Earth's water, which remains constant over time. The video highlights the importance of water in sustaining life and its historical continuity, as the water we use today is the same as that from the time of dinosaurs.

• Hydrologic cycle
