Unit Seven Atmosphere - Moisture in the Atmosphere Flashcards
What are the factors that affect evaporation?
- Temperature
- Surface area
- Relative Humidity
How does temperature affect evaporation?
As temperature increases, evaporation increases.
How does surface area affect evaporation?
As surface area increases, evaporation increases.
How does relative humidity affect evaporation?
As relative humidity increases, evaporation decreases.
Definition of Dew Point
Temperature at which water vapor in air condenses
What is relative humidity?
Amount of moisture in air compared to the air’s maximum capacity.
How is the relative humidity measured and how does it work?
Sling Psychrometer
Two Sides - Dry Bulb and Wet Bulb
Dry Bulb - Measures the air temperature (higher temperature can carry more water due to molecules moving fast)
Wet Bulb - WILL ALWAYS BE LOWER DUE TO EVAPORATION
How are clouds formed?
- Warm air rises
- Air Expands
- Cools Down at the Dew Point
- Condenses into a Cloud
(This Process Cleans the Atmosphere)
What factor likely form clouds?
Air is (saturated or unsaturated)
Saturated
What factor likely form clouds?
Air is (rising or sinking)
Rising
What factor likely form clouds?
Temperature is (at or below) the dew point
At
What factor likely form clouds?
Condensation nuclei (are or are not) present
Are
What factor likely form clouds?
As the air temperature increases, the air can hold (more or less) water
More
