π§ The video discusses the water cycle and how the water we drink today is the same water that existed millions of years ago.
π Water is essential for all living beings on Earth, including plants, animals, and humans.
π The water on Earth continuously circulates in a cycle, which has remained the same for billions of years.
π The water cycle is a continuous process in which water evaporates from the Earth's surface and forms clouds through condensation, eventually falling back to the Earth as precipitation.
βοΈ The sun's heat plays a crucial role in the water cycle by causing the water from rivers, lakes, and oceans to evaporate and turn into water vapor.
π§ The water vapor rises, cools down, and condenses into liquid droplets, forming clouds. When the clouds become saturated, the water falls back to Earth in different forms like rain.
π¦ Precipitation, such as hail, sleet, or snow, collects water that eventually returns to the Earth.
π Water that falls into oceans, lakes, and rivers evaporates and starts a new cycle.
π± Water that falls on the soil becomes groundwater, which is consumed by plants, animals, and humans.
π§ Water is essential for the survival of all living beings.
π The water on Earth has been present for 4 billion years and goes through a continuous cycle of evaporation, cloud formation, and precipitation.
π Water is constantly recycled through rivers, lakes, and oceans.
