Answers Quiz -165 (July 21)

1. B

Explanation: While lightning can create nitrogen compounds, it doesn’t sterilize pollutants. In fact, it may generate ozone or nitrogen oxides, which can contribute to air pollution.

2. D

Explanation: Lightning is most common in areas with high convection, which occurs in warm, moist climates, especially tropical and subtropical regions.

3. B

Explanation: Strong updrafts and downdrafts inside storm clouds cause ice crystals to collide, transferring electrons and leading to negative charge at the bottom and positive at the top.

4. C

Explanation: Lightning is a natural, sudden, and weather-related hazard, hence classified as a hydro-meteorological hazard.

5. B

Explanation: Doppler radar can track storm cells and cloud charge buildup, providing early warnings for lightning strikes, useful for public alerts.
