The stages of the water cycle in nature


water
Water is the source of life on the planet, it is important for all the daily vital processes carried out by living organisms, and constitutes the bulk of the surface of the Earth compared to land, and for man it represents the bulk of the body mass, and this makes it a necessity of human survival, Water in the Earth is found in many forms: oceans, seas, rivers, lakes, fresh ponds, springs, aqueducts and groundwater. The amount of water in the planet is maintained through the so-called water cycle in nature. The stages of the water cycle in the The nature.

The stages of the water cycle in nature
Here is some information about the concept and phases of the water cycle in nature:

The natural cycle of water is defined as a natural chain of successive and related processes, through which the water is reconstituted by changing its physical state from one image to another. This change in the physical state ensures its transition from the surface of the earth to the atmosphere, And storage in the ground.
There are many stages that occur in order to complete the stages of water cycle in nature, and the sun plays a key role in this cycle, so the phases of the water cycle in the natural include:
The sun defrosts the ice and converts it from solid to liquid by heat energy from solar radiation.
Water evaporation of water bodies is carried out through the thermal energy of the solar radiation. The water changes from the liquid to the gaseous state, and rises to the upper layers of the clouds, in addition to the transpiration processes in which the water is evaporated from the plant leaves and turned into gas.
The difference in temperature, wind speed, and atmospheric pressure contribute to the formation of air masses and the occurrence of air depressions through which the precipitation process occurs through the condensation of the clouds. The evaporated water collects in the form of clouds, turning from the gaseous state to the liquid state again.
Once the water reaches the surface of the earth, it is stored underground in the form of groundwater. Plants benefit from the rain in photosynthesis, then evaporate again to reach the upper atmosphere, and then rain to complete the stages of the water life cycle in nature.
The amount of water in the earth and the life cycle of water
The life cycle of the water purifies the water on the surface of the earth for the benefit of living organisms, and in its pure form, where contaminated water affects the life of living organisms and causes the death of many organisms because of the impurities it contains. It is worth mentioning that the stages of the water cycle in nature do not change The amount of water on the surface of the earth but works to reshape this amount of water again.
