Why does a plume of contamination spread out away from the source of contamination?
A plume of contamination spreads out from its source primarily due to the processes of diffusion and advection. Diffusion causes contaminants to move from areas of higher concentration to lower concentration, mixing with surrounding media (like air or water). Advection, on the other hand, involves the movement of contaminants with the flow of air or water, carrying them away from the source. Together, these processes lead to the gradual dispersal of the contaminants over a larger area.

What are two ideas which ideas spread?
They give away farmers and workers from their jobs .
What happens to the illuminance when you move away from the light source?
The intensity decreases.
Why does light get dimmer as you move farther away from the light source?
The decrease in light intensity as you move farther away from the light source is due to the dispersion of light energy over a larger area. This phenomenon follows the inverse square law, which states that the intensity of light is inversely proportional to the square of the distance from the source. As the distance increases, the same amount of light energy is spread out over a larger area, resulting in a decrease in brightness.
How do you make a smaller and clearer shadow when you can not move the object?
Move the light source farther away from the object.
How are light rays coming from a point source of light different then larger source?
From a point source, the light spreads out in all directions and adjacent light waves diverge from one another. From a larger source, it appears more like the light waves are moving parallel to each other, with little divergence. It's a relative thing. From the perspective of Earth, the Sun's rays are all parallel to each other because the Sun is huge and also because we are so far away from it. So the key differences are: 1. Small, point like source. 2. Being close to the source. Combinations of 1 and 2 above produce more divergent rays. Either of 1 and 2 below (or a combination of the two) will produce more parallel rays that don't diverge much. 1. Large light source 2. You're far away from the source.
How far did the contamination of chernobyl spread?
The contamination from the Chernobyl nuclear disaster spread across Europe and beyond, with varying levels of contamination detected in different regions. The most heavily affected areas were in Belarus, Ukraine, and Russia, but radioactive particles were detected as far away as Sweden and Scotland.
Why are cotton stoppers not to set down on the table after use?
They can easily be a source of contamination and must be thrown away or removed.
Why does light spread out as it gets further away from its source?
Light spreads out as it travels further away from its source due to a property called divergence, which causes the light waves to spread out in all directions. This spreading is a result of diffraction, where light encounters obstacles or openings that cause it to scatter or bend.
Why does moving away from a radio affect the loudness you hear?
because sound waves spread out, intensity decreases with distance from the source.
Why is it important to plant blackberries away from raspberries?
It is important to plant blackberries away from raspberries to prevent the spread of diseases and pests that can affect both plants. Planting them apart reduces the risk of cross-contamination and helps maintain the health of each crop.
When the source of a sound is moving the sound waves spread out as it travels away from the listener As this happens what does the listener observe?
a lower-pitched sound
Which wave property decreases as you get farther away from the source of a sound?
The intensity of sound decreases as you get farther away from the source. This is because sound waves spread out in all directions, causing energy to be distributed over a larger area.
What happen to sound as it moves away from it's source?
As sound moves away from its source, it gradually loses intensity and becomes quieter. This is because sound waves spread out in all directions, causing the energy of the sound wave to become more dispersed. The farther you are from the source, the weaker the sound will be.
What is the surface location of a mantle plume called?
The surface location of a mantle plume is called a "hotspot." Hotspots are geologically active areas where magma from deep within the Earth's mantle rises to create volcanic activity, often resulting in the formation of volcanoes or volcanic islands. They can occur away from tectonic plate boundaries and are characterized by a relatively stable source of heat over geological time scales.
What kind waves are spread out?
Waves that spread out are called diverging waves. This occurs when the wave energy travels in multiple directions away from the source, causing the waves to disperse and move further apart as they propagate through a medium.
Why are chemical stored well away from food?
So that there is no cross contamination.
What happens to the intensity of ionizing radiation when you move away?
The intensity of ionizing radiation decreases as you move away from the source due to the inverse square law. This means the radiation intensity decreases proportionally to the square of the distance from the source. As you move further away, the spread of radiation over a larger area reduces the intensity experienced at any one point.
