What are the three major types of clouds?

The three major types of clouds are Cirrus, Cumulus, and Stratus because they represent the primary classifications based on cloud characteristics such as shape and altitude.

Cirrus clouds are high-altitude clouds characterized by their wispy, thin appearance. They are often seen in fair weather but can indicate that a change in the weather is approaching. Cumulus clouds are fluffy, white clouds with a flat base, often associated with fair weather but can develop into larger storm clouds. Stratus clouds are low, uniform clouds that cover the sky like a blanket, often bringing overcast conditions and light drizzle.

These three types serve as the foundational categories for cloud classification, providing a basic framework for meteorological studies. Other options, while they include legitimate cloud types, do not represent the broad overview of major cloud types effectively.
