Science Assessment ~ Topics ~ Weather and Climate I: Basic Elements ~ Misconception WCM066

The main cause of rain falling from clouds is wind blowing on the cloud and making the water in the cloud spill out (AAAS Project 2061, n.d.).

Items that test for misconception WCM066 in this project (Original Project) and key idea (Clouds and rain form as air cools a…)
Item ID Number	Item Description	How Often the Misconception was Chosen
WC080003	Rain forms as the air in a cloud cools, causing tiny water droplets to form and combine to form larger droplets.	43%
WC083002	It will not rain if the tiny water droplets that make up clouds are not heavy enough to fall from the clouds.	14%
WC085002	Rain falls when tiny water droplets in clouds combine to form larger droplets.	13%
WC084002	Rain falls from clouds when air cools, causing water droplets to form.	4%
