But, if that same pot of water is put on a stove and brought to a boiling temperature, the water will evaporate more quickly. During the water cycle some of the water in the oceans and freshwater bodies, such as lakes and rivers, is warmed by the sun and evaporates. During the process of evaporation, impurities in the water are left behind. As a result, the water that goes into the atmosphere is cleaner than it was on Earth. Condensation Condensation is the opposite of evaporation.
Condensation occurs when a gas is changed into a liquid.
Condensation occurs when the temperature of the vapor decreases. When the water droplets formed from condensation are very small, they remain suspended in the atmosphere. These millions of droplets of suspended water form clouds in the sky or fog at ground level. Water condenses into droplets only when there are small dust particles present around which the droplet can form. When the temperature and atmospheric pressure are right, the small droplets of water in clouds form larger droplets and precipitation occurs.
