The constant movement of water between Earth and the atmosphere is called the

Precipitation
water cycle
humidity
water cycle
The water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth. It is a closed system driven primarily by solar energy, involving changes in the physical state of water.

P=E+╬ФS+R тАФ The water balance equation for a catchment area, where P is precipitation, E is evapotranspiration, R is runoff, and ╬ФS is the change in storage.
The process is driven by solar radiation which causes evaporation of water from oceans and land surfaces. Water vapor rises, cools, and undergoes condensation to form clouds, eventually returning to the surface as precipitation. Surface runoff and infiltration then return water to collection points, completing the cycle.
The water cycle is a closed system; the total amount of water on Earth remains essentially constant.
Major phases include Evaporation, Transpiration, Condensation, Precipitation, and Collection/Runoff.
Hydrology is the study of the distribution, movement, and management of water within the Earth's hydrosphere.
Regulates global temperature and climate.
Provides a renewable source of freshwater through natural purification.
Susceptible to disruption by anthropogenic climate change.
Causes extreme natural events like floods and droughts when the cycle is unbalanced.
Water resources management and irrigation design.
Flood forecasting and dam infrastructure planning.
Sleet is a specific form of frozen precipitation, not the cycle itself.
Precipitation is just one component of the hydrologic cycle.
Humidity refers to the amount of water vapor present in the atmosphere, representing a state rather than the movement cycle.
C is correct тАФ The water cycle represents the continuous movement of water within the Earth's hydrosphere, involving phase changes and transport mechanisms.
In hydrology exams, always remember that 'Evapotranspiration' (E + T) is the dominant loss term in the annual water balance of a river basin.
