Water is the most common liquid on Earth. It covers about 71.4% of the Earth. Pure water has no smell, taste, or color. Lakes, oceans, and rivers are made of water. Rain is water that falls from clouds in the sky. If water gets very cold (below 0 degrees Celsius), it freezes and becomes ice. Frozen rain is hail. Snow is formed from water vapor, not rain. If water gets very hot (above 100 degrees Celsius), it boils and becomes steam. Water is very important for life. However, some studies suggest that by 2025 more than half of the people around the world will not have enough water.
