Explanation:
According to the research, the correct option is Most of the water that falls on the continents is derived from the oceans. It is true about the hydrological cycle.
<h3>What is the
hydrological cycle?</h3>
It is the water cycle that allows water to pass from the earth's surface to the atmosphere so that it can then return to its liquid and solid phases. .
In this process, therefore, sublimation, evaporation and transpiration play an essential role where 70% of the earth's surface is covered by liquid water, of which 97% is salt water that forms the oceans.
Therefore, we can conclude that according to the research, the correct option is Most of the water that falls on the continents is derived from the oceans. It is true about the hydrological cycle.
