Weathering Clouds

Clouds

I can classify clouds by their shape and height.

I can describe and predict weather conditions based on cloud types.

CLOUDS!

• Clouds form when water vapor condenses into tiny water droplets or ice crystals.

• After clouds form, the tiny water droplets or ice crystals keep combining.

• When the water drops or ice crystals become too heavy, they fall to Earth as a form of precipitation.
