  1. Cloud Formation Clouds and Cloud Formation Mr. Fetch’s Earth Science Classroom

  2. What is a cloud? Clouds: groups of tiny water drops. CLOUDS FORM WHEN: Mr. Fetch's Earth Science Class Mr. Fetch’s Earth Science Classroom

  3. 4 Ways to get air to rise. Mr. Fetch's Earth Science Class Mr. Fetch’s Earth Science Classroom

  4. Convective Lifting Air BACK Mr. Fetch's Earth Science Class Mr. Fetch’s Earth Science Classroom

  5. Orographic Lifting Air BACK Mr. Fetch's Earth Science Class Mr. Fetch’s Earth Science Classroom

  6. Frontal Lifting Cold Air Warm Air BACK Mr. Fetch's Earth Science Class Mr. Fetch’s Earth Science Classroom

  7. Convergence Air Air BACK Mr. Fetch's Earth Science Class Mr. Fetch’s Earth Science Classroom

  8. Air cools when it expands Air Air Air Air Mr. Fetch's Earth Science Class Mr. Fetch’s Earth Science Classroom

  9. Cooling air causes it to Condense The temperature when condensation begins is called the Dewpoint Temperature. Air cools by expanding. Cooling air increases Relative Humidity. Air becomes full of water } SATURATED Water condenses out of the air. GAS  LIQUID Clusters of water drops are called clouds. Dust and salt in the atmosphere are examples of condensation nuclei Mr. Fetch's Earth Science Class Mr. Fetch’s Earth Science Classroom

  10. Summary: Cloud Formation AIR CONDENSES AIR COOLS AIR RISES By expanding Convection Orographic Lifting Frontal Lifting Convergence Cools to the dewpoint and water vapor condenses. Mr. Fetch's Earth Science Class Mr. Fetch’s Earth Science Classroom
