The stage of water cycle where water moves downward from the force of gravity is runoff.
It comes after the precipitation stage when the water has fallen in a form of rain and seep through the soil, due to the force of gravity this water moves down the hills and mountains through a process called runoff.
Under the force of gravity, water follows along the steep hills and then join into stream and rivers. Later on these streams and rivers will move down to join lakes and oceans.
Precipitation, Surface Runoff and Infiltration process
Explanation:
There different stages of the water cycle where the water comes back on earth due to the gravitational force are as follows-
Rainfall/Precipitation- The water vapour in the cloud undergoes the process of condensation, it leads to the occurrence of rainfall, where the water comes freely over the ground surface from a certain height.
Surface Runoff- These refer to the flow of water rapidly along a steep slope, under the influence of gravity that eventually adds to the streams, lakes and rivers.
Infiltration process- This is the process where the water from the earth's surface percolates through the rocks and flows downward and eventually mixes with the groundwater.
