True

A cloud can weigh more than a million pounds, and cumulus clouds are heavy due to water droplets.

Infact verdict: True (91/100).

Both claims about cloud weight are supported by multiple reliable sources. Clouds, including cumulus clouds, can indeed weigh millions of pounds due to the vast amount of water droplets they contain. Despite their weight, they float because the water is spread out over a large volume, making them less dense than the surrounding air.

True Science
Cumulus clouds are packed with water droplets, making them incredibly heavy despite floating in the air.
Reliable sources, including Wikipedia and social media posts from Mechanical Mind, confirm that cumulus clouds can weigh hundreds of tons due to the water droplets they contain. They float because their density is lower than the surrounding air.
