We used page #46:

~You need water vapor in the air,

~The temp. needs to be below the dew point.

~The water wapor need to have something it can condense on.

Not bad...a 3/4. Explaing what dew point is. ALso, what does it mean "to have something to condense on"?

dew point is the temp. when air cannot hold any more water wapor.

"to have something to condense on" means that the water wapor needs something such as dust to hold on to to form a cloud.

I think you've got it!!
