The hydrosphere, this important terrestrial layer where water exists, like the atmosphere, is always in motion through the hydrologic cycle also called the Water Cycle. Water does not remain static in one place of the earth's surface, but is in constant motion, shuffling from one place to another. It moves from the oceans to the continents, it passes through the atmosphere and returns to the Earth's crust. This movement is called the Water Cycle, which comprises the following steps:
Evaporation
It occurs due to the solar energy, and basically water becomes gaseous (vapor). Trees and plants are also involved in the cycle, the water rises up the stem and leaves from the roots and turns into vapor by transpiration.
Condensation
It happens when water vapor in the atmosphere liquefies and forms clouds. If the air’s temperature is below the freezing point, ice crystals will form around dust particles.
Precipitation
It is the fall of liquid or solid water, which is rain and hail or snow respectively.
