By the end of the week, clouds are much more likely to be saturated with moisture and CCN. This is because during the week, millions of cars release exhaust into the atmosphere, creating billions of CCN in the clouds. In urban areas, where many vehicles are on the road at once, rainfall is more likely during the weekend than during the week. Burning fossil fuels can influence rain patterns. These pollutants can also be released by human activity, such as the burning of fossil fuels. Sulfur dioxide and nitrogen oxide can be released into the atmosphere naturally, such as through a volcanic eruption. This is called acid rain. Acid can harm plants, aquatic animals like fish and frogs, and the soil. When rain forms around certain types of pollutants, such as sulfur dioxide and nitrogen oxide, the CCN react with water to make the rain acidic. Because CCN are so tiny, however, color is rarely visible. Brightly colored CCN, such as red dust or green algae, can cause colored rain. CCN can be particles of dust, salt, smoke, or pollution. Raindrops condense around microscopic pieces of material called cloud condensation nuclei (CCN). Governments, groups, and individuals collect rain for personal and public use. Rain makes modern life possible by providing water for agriculture, industry, hygiene, and electrical energy. Rain is the source of freshwater for many cultures where rivers, lakes, or aquifers are not easily accessible. When the water droplet becomes too heavy to continue floating around in the cloud, it falls to the ground. As this continues to happen, the droplet gets heavier and heavier. When a small water droplet bumps into a bigger one, it condenses, or combines, with the larger one. Millions of water droplets bump into each other as they gather in a cloud. Raindrops fall to Earth when clouds become saturated, or filled, with water droplets. Rain is liquid precipitation: water falling from the sky.
