Final answer:
The dust in a dust storm that extends thousands of feet above ground is composed of various sizes of particles, ranging from sand-sized particles to fine dust or particulate matter. The larger particles are typically sand-sized, ranging from 0.06 to 2 millimeters in diameter, while the smaller particles can be as small as 2.5 micrometers.
Step-by-step explanation:
The dust in a dust storm that extends thousands of feet above ground is composed of various sizes of particles.
At the larger end of the size spectrum, dust particles in a dust storm can reach heights of thousands of feet above ground level. The larger particles are typically sand-sized, ranging from 0.06 to 2 millimeters in diameter.
However, there are also smaller particles in a dust storm that are carried high into the atmosphere. These smaller particles, known as fine dust or particulate matter, can be as small as 2.5 micrometers, which is about 0.0001 inches.
