What fraction of the solar flux absorbed by the Earth's surface drives the hydrologic cycle:
Show answer Hide answer
Answer: B. 1/3rd
Explanation
Solar radiation reaching the Earth provides the thermal energy required to evaporate surface water. A significant fraction of this absorbed solar flux powers global atmospheric water circulation. Calculations show that roughly one third of incoming solar energy drives the hydrologic cycle. The hydrologic cycle describes the continuous movement of water on, above, and below the Earth surface. Solar flux measures the total amount of solar electromagnetic radiation received per unit area. Evaporation and transpiration require massive amounts of latent heat energy supplied by the sun.
Global climate patterns are heavily influenced by the solar energy driving atmospheric moisture transport. Agricultural irrigation planning depends on understanding local evaporation rates driven by solar flux. Meteorologists study the hydrologic cycle to forecast weather events and precipitation distributions. One half second is a time unit and does not represent a fraction of absorbed solar radiation. One fourth represents an underestimation of the solar energy fraction dedicated to the water cycle. One fifth underestimates the substantial thermal energy required to sustain global hydrologic movement.
