GEOLOGY

Detailed explanation-1: -Hence, the gravitational force is responsible for the flow of water in rivers.

Detailed explanation-2: -The two most important forces controlling water movement in rock are gravity and molecular attraction. Gravity causes water to infiltrate until it reaches impermeable zones where it is diverted laterally. Gravity generates the flow of springs, rivers, and wells.

Detailed explanation-3: -Water is able to soak up against the force of gravity all thanks to a little help from capillary action. Water is wet. In scientific terms, wetting refers to the tendency of a liquid to stick to a solid. Water molecules are electrically polar, with positively charged hydrogen atoms and negatively charged oxygen atoms.

Detailed explanation-4: -Gravity pulls the water down into the Earth, so as you go progressively deeper in the soil, the pore spaces become more and more full. When water fills every pore, the soil is saturated.

Detailed explanation-5: -Water flows downhill because gravity is a form of potential energy – and the water, or anything that falls or rolls downward – flows in response to differences in potential energy (from high to low).
