3. Which steps of the water cycle are driven by the
sun?
Evaporation and Condensation
4. Which steps of the water cycle are driven by
gravity?
Precipitation and Runoff
5. Draw and label the 4 steps to the water cycle on

7. What causes winds?
A difference in temperature creates a difference in
pressure. Air molecules move until they are evenly
spread out
8. Air goes from ___​High​ ___ Pressure to
___​Low​___ Pressure
9. What part of earth has the most direct sunlight?
Equator
10. What part of earth has the least direct sunlight?
Poles
11. How does Earth’s rotation impact wind direction?
Causes winds to curve
12. Explain why winds move from the water to a
beach (land) during the day. Mention
temperature, pressure, and why they move.
Winds move from the water (high pressure) to the beach
(low pressure) because the molecules are trying to be
evenly spaced / balanced.

8.3.3 → Air Masses and Fronts
14. How is an air mass different from an air front?
Air Mass = Large body of air that takes on the
characteristics of the land/water below it
Air Front = Boundary between two air masses; where
they meet

17. Describe a cold front
A cold air mass quickly moves in and pushes the warm
air mass up
18. Describe a warm front
A slow moving warm air mass moves in and above the
cold air mass
19. Describe a stationary front
Two air masses meet and they move sideways
20. What are 3 pieces of evidence a cold front
occurred?
○ Cumulonimbus Clouds
○ Thunderstorms Occur
○ Significant drop in Barometric Pressure
○ Cold weather follows
21. What are 3 pieces of evidence a warm front
occurred?
○ Stratus / Nimbostratus Clouds
○ Hours / days of Steady Rain
○ Barometric Pressure drops slightly
○ Warm weather follows
