what is hydrologic
Cycle
Answers
Answer:
The hydrologic - or water - cycle is the continuous movement of water between the earth and the atmosphere. Water reaches land as precipitation such as rain and snow. Then the water evaporates, condenses in the atmosphere to form clouds, and falls to the earth again as precipitation, continuing the cycle. When water falls to the ground it can collect on the land becoming streams, rivers, lakes, or soaks in to the ground to become groundwater. Plants take up groundwater either using it or releasing it to the atmosphere.
Impotrance of hydrological cycle : -
i) Required for solubilization of chemicals and several biochemical reactions like hydrolytic digestion of polymeric nutrients, photosynthesis, etc.
ii) Important for the working of macromolecules, as a good ionizer, transport of materials, etc.
iii) Acts as a habitat for hydropyhtic and aquatic animals and as an agent of geological change.
iv) Acts as an agent of energy transfer and use. Water is a tremendous factor in neutralising heat radiations of sunlight, so also acts as a 'temperature buffer
