300
What does an isotherm measure?
Temperature
300

As warm air rises, it expands and cools allowing the water vapor to condense. What is formed during this?
How clouds form.
400
What is the movement of air caused by differences in air pressure?
Wind
400

500
What processes put water vapor into the atmosphere?
evaporation and transpiration
500
Describe runoff
occurs when there is more water than land can absorb. The excess liquid flows across the surface of the land and into nearby creeks, streams, or ponds.
500
The amount of water vapor in the atmosphere at any given point describes what?
humidity
