Forms of Water
Water takes many different forms on Earth.
- Water vapor and clouds in the sky;
- Seawater and rarely icebergs in the ocean;
- Glaciers and rivers in the mountains;
- Aquifers in the ground.
Water can dissolve many different substances imparting upon it different tastes and odours. In fact, humans and other animals have developed senses to be able to evaluate the potability of water.
- Animals generally dislike the taste of salty sea water and the putrid swamps and favor the purer water of a mountain spring or aquifer.
- The taste advertised in spring water or mineral water derives from the minerals dissolved, while pure H2O is tasteless. As such, purity in spring and mineral water refers to purity from toxins, pollutants, and microbes.
