Question

1. what are cirrus, cirrostrat and cirrocumulus clouds made of?

Explanation:

Cirrus, cirrostratus, and cirrocumulus clouds are high - level clouds. High - level clouds form at altitudes above 20,000 feet (6,000 meters). At such high altitudes, the temperature is very low, so these clouds are made of ice crystals. This is because the cold temperatures at those heights cause water vapor to directly freeze into ice crystals rather than condense into liquid water droplets.

Answer:

Cirrus, cirrostratus, and cirrocumulus clouds are made of ice crystals.
