PDE Q43

Cirrus clouds are high-altitude clouds found at heights above 6,000 meters. They are thin, wispy, and made mostly of ice crystals due to the cold temperatures at such high elevations. These clouds usually indicate fair weather but can also signal that a change in the weather is coming.

• Option A: a low cloud
  Incorrect. Low clouds include types like stratus and cumulus, not cirrus.

• Option B: a rain-bearing cloud
  Incorrect. Rain-bearing clouds are typically nimbostratus or cumulonimbus.

• Option C: a high-cloud
  Correct. Cirrus clouds are high-altitude clouds made of ice crystals.

• Option D: a hail-bearing cloud
  Incorrect. Hail is usually associated with large cumulonimbus clouds during thunderstorms.
