Why are clouds at different heights?
Show answer & explanation
Answer: Temperature and moisture vary
Heavy clouds sink lower — Wrong. Clouds don't sink from weight—they form at altitudes where temperature/moisture conditions allow condensation. Cloud type determines height.
Older clouds rise higher — Wrong. Clouds don't age upward—they form at specific altitudes based on atmospheric conditions (temperature, moisture, stability).
Temperature and moisture vary ✓ — Correct! Atmospheric layering! Cloud heights vary by type: (1) Low clouds (0-2km)—stratus, cumulus (warm, moist air). (2) Middle clouds (2-6km)—altostratus, altocumulus (cooler). (3) High clouds (6-12km)—cirrus, cirrostratus (cold, ice crystals). (4) Vertical clouds—cumulonimbus (ground to 12km+ in severe storms). Temperature decreases with altitude—determines where water vapor condenses. Dew point + temperature = cloud base. Stable air: layered clouds. Unstable: vertical development. Lenticular clouds: mountain waves!
