The meaning of 'water'

Water is a transparent, tasteless, and nearly colorless liquid essential for all known forms of life. It’s composed of two hydrogen atoms bonded to one oxygen atom (H₂O). Water covers about 71% of Earth's surface and exists in oceans, lakes, rivers, and underground. It acts as a solvent, meaning it can dissolve many substances, which is vital for biological processes. Water also regulates temperature, supports ecosystems, and is used for drinking, agriculture, industry, and sanitation. Its unique properties make it fundamental to sustaining life and maintaining the planet's environmental balance.
