Water is a colorless, odorless, and tasteless liquid that is essential for all forms of life. It covers about 71% of the Earth's surface and is found in oceans, rivers, lakes, and glaciers. Water molecules consist of two hydrogen atoms bonded to one oxygen atom (H2O). It exists in three states: liquid, solid (ice), and gas (vapor). Water is crucial for various biological processes such as hydration, digestion, and temperature regulation.
