HYDROLOGIC PROCESS

What Is Hydrologic Cycle???

• The hydrologic cycle also known as the water cycle, describes the continuousmovement of water on, above and below the surface of the Earth.
• Since the water is truly a “cycle,” there is no beginning or end. Water can change states among liquid, vapor and ice at various places in the water cycle.
• Most of the earth’s water is stored in the oceans, but solar energy continually evaporate this water, and winds distribute water vapor around the globe
• Water that condenses over land surfaces, in the form of rain, snow, or fog, supports all terrestrial (land-based) ecosystem
• Living organism emit the moisture they have consumed through respiration and perspiration.
• Eventually this moisture reenters the atmosphere or enters lakes and streams, from which it ultimately returns to the ocean again
• As it moves through living things and through the atmosphere, water is responsible for metabolic processes within cells, for maintaining the flows of key nutrients through ecosystems, and for global-scale distribution of heat and energy
