What are the three main types of clouds?

The three main types of clouds are cumulus, stratus, and cirrus, which together represent distinct cloud formations based on their appearance and altitude.

Cumulus clouds are typically fluffy and white with a puffy appearance, often associated with fair weather but can develop into larger storm clouds. They form as warm air rises and cools, causing moisture to condense.

Stratus clouds are uniform gray clouds that often cover the entire sky, resembling a blanket. They usually bring overcast conditions and can produce light rain or drizzle. These clouds form in stable air where the moisture gradually rises and spreads out horizontally.

Cirrus clouds are high-altitude clouds that appear wispy and thin, composed of ice crystals. They indicate fair weather but can also signal that a change in the weather is coming.

The correct choice encompasses the basic classifications of clouds that are widely recognized in meteorology, allowing for a systematic understanding of cloud types and their associated weather patterns.
