Welcome to Mr. Ullrich's Blog! This blog is for 8th Grade Earth Science and Physical Science students. We will learn topics such as Astronomy, Geology and Meteorology. This blog will give us a place to discuss, learn and develop these topics during the year. If you are not from our class please post lots of comments!
Clouds form when moist air and cold, dry air combine. There are three components are necessary for clouds to form: water vapor, cool or cold air, and condensation nuclei. Condensation nuclei are particles of dust or dirt that are in the air. This dust might come from volcanoes, cars, or fires. The water vapor comes from water evaporating anywhere on the earth’s surface. The cold or cool air comes from how high the clouds form.
