GEOLOGY

Detailed explanation-1: -Water Moves with Gravity All water flows downhill because gravity causes it to do so, so both surface and groundwater flow from high to low. However, with groundwater, it moves depending on the elevation of the water table.

Detailed explanation-2: -It runs over the surface into rivers, lakes or the ocean, and becomes surface water, or it soaks into the earth and becomes groundwater. When water enters soil-infiltration-gravity pulls it down through the unsaturated zone where spaces between soil particles are empty and water can readily pass through.

Detailed explanation-3: -In contrast to surface water, groundwater is separated from the atmosphere, and as a result it may also be under considerable pressure. As a result, the potential energy that drives groundwater movement includes both pressure and gravity.

Detailed explanation-4: -Explanation: When you put something in water, gravity can pull the object down through the water only if an equal volume of water is allowed to go up against the force of gravity; this is called displacement. In effect gravity has to choose which it will pull down, the water or the immersed object.
