The water cycle is the name given to the process that occurs in nature involving the chemical, water. The Sun heats the world’s oceans, which slowly evaporate, releasing water vapor into the atmosphere. As the water vapor rises, it cools and condenses into water droplets. These droplets form clouds, which release their water back to Earth as rainfall. Rivers carry the liquid water back into the sea, where the process begins again. The water cycle hydrates the Earth and makes human life possible.
Discovering The Cycle
People have asked the question, “What is the water cycle” ever since they have understood how water changes. Liquid water is the most powerful solvent yet discovered. Given enough time, water can dissolve almost anything. “What is the water cycle” has given rise to powerful ideas about nature. In time, the water cycle has proved to be one of the most astounding facts found in nature.
Water can be divided into two categories: freshwater and seawater. Seawater has a high salt content, which makes it bad for humans and animals to drink. Saltwater animals like fish can survive in seawater, but only freshwater is drinkable by land animals and humans. The supply of freshwater is important for the continued survival of most species of mammals.
Importance Of Freshwater To Life
Freshwater is created by the natural distillation that occurs during the water cycle. As the Sun heats the oceans, the evaporated water leaves the salt behind. The salt is too heavy to travel with the water, so the evaporated water is turned into freshwater. When this water falls as rain and snow, the lakes, rivers and streams carry the freshwater back into the ocean. The freshwater present in bodies like lakes and rivers is used by animals and humans for their needs. Humans use freshwater to drink and keep their work and living spaces clean. Animals also use it to bathe and drink.
Freshwater, Plant And Animal Life
Potable water is an important natural resource Life congregates around areas of freshwater created by the water cycle. In the Nile river delta in Egypt, greenery thrives due to the freshwater from the Nile. Surrounding the delta is a sea of sand, parched of almost every living thing. Water is essential for plant and animal life. Freshwater and plant and animal life are almost always found together. The water cycle makes life on Earth possible by making freshwater so widely available.
