when are impurities such as dust and particulates removed from the atmosphere?
○ during evaporation and transpiration
○ during condensation and precipitation
○ during condensation and evaporation
○ during runoff and precipitation

Explanation:

To determine when impurities like dust are removed from the atmosphere, we analyze each stage:

• Evaporation/Transpiration: These involve water turning to vapor, not removing impurities.
• Condensation: Water vapor condenses around dust particles (acting as condensation nuclei), capturing them.
• Precipitation: Rain, snow, etc., falls, carrying the dust - laden water (with impurities) to the ground.
• Runoff: Occurs after precipitation, moving water on the surface, not removing impurities from the atmosphere.

So, impurities are removed during Condensation (capturing on particles) and Precipitation (carrying to the ground).

Answer:

B. during Condensation and Precipitation
