Which of the following is NOT a source of particulate matter (PM2.5)?
A. Vehicle exhaust
B. Solar radiation
C. Industrial emissions
D. Burning fossil fuels
Answer: Option B
Solution (By JKSSB Mock Tests)
Solar radiation is not a source of particulate matter. Particulate matter (PM2.5 and PM10) is emitted from vehicle exhaust, industrial processes, burning of fossil fuels, construction, and natural sources like dust and smoke.
Explanation:
The exosphere is characterized by increasing temperature with altitude, as the few gas molecules present absorb solar radiation. It is the outermost layer, merging with space.
Explanation:
Tornadoes are not a type of tropical cyclone. Hurricanes, typhoons, and cyclones are all regional names for tropical cyclones. A tornado is a localized, violent rotating column of air extending from a thunderstorm to the ground.
