The correct answer is option C: Sedimentation.
Explanation:
Sedimentation is the process by which solid particles settle down in a liquid. When a solid is mixed with a liquid, the solid particles disperse and remain suspended in the liquid for some time. However, due to the force of gravity acting on the particles, they eventually settle down at the bottom of the container. This settling down of particles is called sedimentation.
Sedimentation is a natural process that occurs due to the difference in density between the solid particles and the liquid. Heavier particles settle down faster, while lighter particles take longer to settle. The process of sedimentation is commonly observed in nature, such as when sand settles down in water or when mud settles at the bottom of a river.
Sedimentation is an important process used in various industries and in our daily lives. Some examples of its applications include:
1. Water Treatment: Sedimentation is an essential step in water treatment plants. When water is taken from natural sources like rivers or lakes, it contains suspended impurities and particles. These impurities need to be removed before the water can be used for drinking or other purposes. Sedimentation tanks or clarifiers are used in water treatment plants to allow the solid particles to settle down, leaving the clear water on top.
2. Mining: Sedimentation is used in the mining industry to separate valuable minerals from the ore. The ore is crushed and mixed with water to form a slurry. The slurry is then allowed to settle, and the valuable minerals settle at the bottom, while the waste material floats on top.
3. Soil Erosion: Sedimentation plays a role in soil erosion. When there is heavy rainfall or poor land management practices, the top layer of soil can be eroded and carried away by water. This eroded soil eventually settles down in nearby water bodies, causing sedimentation and affecting water quality.
In conclusion, sedimentation is the process of settling down of particles of a solid in a liquid due to the force of gravity. It is a natural phenomenon observed in various settings and has practical applications in industries like water treatment and mining.
