Question

What is particulate Matter?
What is radioactive pollutants?
From where does smoke comes in the atmosphere?​

Answer 1

Answer:

1) Particulates – also known as atmospheric aerosol particles, atmospheric particulate matter, particulate matter, or suspended particulate matter – are microscopic particles of solid or liquid matter suspended in the air.

2) Radioactive contamination, also called radiological contamination, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids or gases, where their presence is unintended or undesirable. 

3) This is because of the heating of the earth's surface during the day. The air just above the surface becomes heated and expands. In turn, it begins to rise, since it is lighter, resulting in vertical movement in the atmosphere. The more unstable, the higher smoke will be lifted.

Answer 2

1.Particulate matter is the sum of all solid and liquid particles suspended in air many of which are hazardous. This complex mixture includes both organic and inorganic particles, such as dust, pollen, soot, smoke, and liquid droplets.

2.Radioactive pollution happen when there is presence of radioactive material like Uranium are in environment due to presence accidental or present due to radioactive decay.

3.This is because of the heating of the earth's surface during the day. The air just above the surface becomes heated and expands. In turn, it begins to rise, since it is lighter, resulting in vertical movement in the atmosphere. The more unstable, the higher smoke will be lifted.
