Which statement about lifting condensation level is correct?

• A. The altitude where air becomes saturated during ascent.
• B. The altitude of the tropopause.
• C. The altitude where rising air first forms visible clouds.
• D. The altitude where rain begins.

Answer: (C)

Lifting condensation level is the height at which a rising air parcel becomes saturated and cloud droplets first form. That moment is what you observe as the first visible clouds. So the best description is the altitude where rising air first forms visible clouds, because condensation has begun and cloud droplets become noticeable there. The tropopause is a much higher boundary, rain begins after clouds have developed further, and simply saying the air becomes saturated during ascent describes the process but doesn’t tie it to the observable cloud formation that defines the LCL.
