Temperature is a major factor in evaporation, the transfer of water from the hydrosphere to the atmosphere. The higher a location's temperature, the more easily water evaporates at that location.

7. Based on temperatures near the equator and the poles, describe how the hydrosphere and the atmosphere interact at each location.

8. Think about how quickly or slowly evaporation occurs at your location. (For instance, consider how long it takes a damp towel to dry out.) Describe interactions between the hydrosphere and atmosphere you can infer for your location.
