Water is found in many places on Earth including on the surface of the planet, within rocks below the surface, and in the atmosphere. Water travels between different areas of the Earth through the water cycle.
About 70% of the Earth surface is covered with water, and most of that is the ocean. Only a small portion of the Earth's water is freshwater, which is found in rivers, lakes, and groundwater. Freshwater is needed for drinking, farming, and washing.
Without water, life as we know it would not exist.
