Answer:
Precipitation, runoff and percolation
Explanation:
The water cycle refers to the movement of water from one place to another by undergoing certain processes such as evaporation, transpiration, condensation. This plays an important role in maintaining the total amount of water on earth.
From the figure, it can be concluded that the process of precipitation, runoff and percolation are the three stages in which the water moves downward due to the influence of gravity.
The precipitation occurs in the form of snowfall, rainfall, and so on. This allows the water to fall freely because of gravity.
The surface water runoff also occurs under the influence of gravity, that rapidly falls downward along the slope of the area and gets mixed up with the rivers, streams and lakes.
Lastly, during the water cycle process, some of the water gets percolate downward through the voids present within the rocks. Here the water moves because of the effect of gravity but at a much slower rate. This water then slowly adds to the groundwater.
