Lesson 3

How would increased temperatures affect evaporation?

Lesson Objectives...

Analyze evaporation investigation data for patterns to provide evidence that increased temperatures cause an increase in evaporation leading to more water vapor entering the atmosphere.
Modify a model - based on evidence - to match how a change in atmospheric temperature causes a change in evaporation in Earth’s water system.

Increased temperatures lead to increased evaporation rates and more water vapor in the atmosphere.
Evaporation happened in all cases, but more moist conditions had higher evaporation rates than drier conditions.
The amount of water vapor is not the same for every location and winds move the water vapor to different locations.
Drought areas may be getting drier when water vapor moves away from the location, while flood areas may be getting wetter when more water vapor moves toward the location.
Cooler ocean water and landforms may affect how much water vapor gets to a location.
