Which process included in hydrological cycle?
precipitation
runoff
evaporation
all of the above
all of the above
The hydrological cycle, or water cycle, is the continuous movement of water on, above, and below the Earth's surface. It encompasses processes like evaporation, transpiration, condensation, precipitation, and runoff, collectively driven by solar energy and gravity.

P=E+R+╬ФS тАФ The basic water budget equation where P is precipitation, E is evaporation, R is runoff, and ╬ФS is the change in storage.
Solar radiation heats water bodies, causing evaporation from surfaces and transpiration from vegetation. This water vapor rises, cools, and undergoes condensation to form clouds, eventually returning to the Earth as precipitation. Gravity then drives the movement of this water as runoff, infiltration, and percolation, completing the cycle.
The hydrological cycle is a closed system with respect to mass, meaning the total mass of water remains constant.
Solar radiation is the primary energy source driving the cycle.
Gravity is the primary force responsible for runoff and groundwater flow.
The cycle regulates global temperature and sustains terrestrial life.
Maintains continuous water supply for ecosystems.
Purifies water through natural evaporation and distillation processes.
Uneven distribution leads to water scarcity in certain regions.
Extreme events like floods and droughts disrupt human activity.
Estimation of catchment yield for dam design.
Flood forecasting and irrigation scheduling.
Water resource management and sustainability analysis.
The process is essentially a thermodynamic system involving latent heat transfer.
Runoff (R) refers to the portion of precipitation that eventually drains into streams and rivers.
D is correct тАФ Precipitation, runoff, and evaporation are all fundamental components of the continuous global hydrological cycle.
When analyzing water resource problems, always remember the continuity equation InflowтИТOutflow=╬ФStorage as it is the foundation for solving hydrological balance questions.
