Which term describes the process that continually moves water from the ground to the atmosphere and back? , a evaporation cycle b humidity cycle c transpiration cycle d water cycle

This process is D, the Water Cycle.

Though we may only think about the water cycle being above ground, some stages of it are below ground as well, such as percolation. The main steps of the water cycle are evaporation, condensation, and preciptation. Though there are others like aformentioned percolation as well as runoff and transpiration. Evaporation happens when hte sun's energy heats up the water in the oceans and in various sources such as lakes and then turns it into water vapor. The water vapor then rises. When it gets cold enough, the water vapor condeses and forms clouds. Finally, when the clouds are big enough, the 'burst' and create precipitation to have the cycle start all over again. But this cycle isn't exactly 'fair' for all parts of the earth, because some parts get too much water while some get too little.
