Correct Option
The correct option isIt facilitates the evaporation of water from surfaces.
Explanation
The hydrological cycle (water cycle) is a continuous process driven primarily by solar energy. This energy influences the physical state of water and the dynamics of the atmosphere, enabling the movement of water between the hydrosphere, atmosphere, and lithosphere.
Detailed Analysis
- It facilitates the evaporation of water from surfaces. is Correct: Solar radiation heats both water bodies and the air above them. As water absorbs heat energy, its molecules gain kinetic energy and transition from a liquid to a gaseous state (evaporation). Furthermore, heated air expands, becomes less dense, and rises. Warmer air has a higher water vapor holding capacity compared to cooler air, which actively facilitates the uptake of moisture from surfaces, thereby driving the evaporation process.
- It causes immediate precipitation. is Incorrect: Precipitation occurs when moist air cools, causing water vapor to condense into liquid droplets or ice crystals. Heating air increases its capacity to hold vapor, which tends to delay rather than cause immediate precipitation.
- It freezes water vapour into hail. is Incorrect: The formation of hail involves the freezing of supercooled water droplets in strong updrafts within cumulonimbus clouds. This process requires freezing temperatures, not heating.
- It prevents the formation of clouds. is Incorrect: Heated air rises and undergoes adiabatic cooling as it reaches higher altitudes. This cooling leads to condensation and the formation of clouds. Therefore, heated air is the mechanism that initiates the vertical movement necessary for cloud formation, rather than preventing it.
Key Takeaway: Solar energy acts as the engine of the water cycle by heating water to cause evaporation and heating air to facilitate the upward transport of moisture (convection), which is essential for subsequent condensation and precipitation.
