Water is a clear, colorless, and tasteless liquid that is essential for all forms of life. It covers about 71% of the Earth's surface and exists in three states—solid (ice), liquid (water), and gas (water vapor). Water plays a crucial role in maintaining the balance of ecosystems and is vital for drinking, agriculture, sanitation, and industry.It is made up of two hydrogen atoms and one oxygen atom (Hâ‚‚O). Despite its abundance, clean and safe drinking water is limited in many parts of the world. Conserving water and protecting it from pollution are important steps toward ensuring a sustainable future
