What does dispersion mean in earth science?
dispersion occurs when particles spread out over a larger area. For example, when a stone is thrown into water, the particle initially forms a small round plume of water. As the plume widens out, it becomes less dense and less likely to sink to the bottom. Dispersion can also describe the way that particulate matter moves through the atmosphere as it is blown by the wind or convected by currents.
What does the word dispersion mean in earth science?
This term has two meanings: in the context of human activities, it means spreading out, whereas for natural processes, it means spreading out or breaking up. For example, when you pour flour into a bowl of water, the flour will form a small mass in the middle. If you spin it, the flour will disperse and its particles will spread out in the water. However, if you simply drop the flour into the water, it will gradually break up into smaller and smaller pieces.
What does the word disperse mean in earth science?
When a solid is added to another solid, it can change the properties of the first solid. For example, sand can act like a lubricant when it is added to dry clay. This is known as dispersion because the small grains of sand appear to “disperse” throughout the larger particles of clay. Dispersions are not limited to dry materials. Water is also a dispersant. Water can reduce the strength of a rock, making it easier to break. So, in the
What does the word dispersion mean in earth science majors?
Dispersion refers to the spreading out of particles into a wider area. Common examples of dispersion in earth science are: the movement of water, air, and dust. The movement of water and air are usually toward the atmosphere, while dust will tend to move toward the surface of the earth. Dispersions can also occur on a smaller scale, such as the spreading of foam on a lake or a rain shower dousing a lawn.
What does the word dispersion mean in astronomy?
Dispersions are the process of separating or spreading out matter. In astronomy, a dispersed object is one that is spread out over a large area – an example is a comet. Dispersions are used in the analysis of the orbits of objects in the Solar System, to figure out where they came from, where they are now, and how they will move in the future.
