Bill's science class wanted to determine what type of environments were the most humid. They created a desert and a beach environment inside two identical 2 Liter plastic Coca-Cola bottle in their science class. They put the same brand of humidity probe inside the bottles and set the bottles in front of heat lamps then measured the humidity every 3 minutes for a total of 15 minutes. What was the independent variable in this experiment?
The type of environment
The layer if gas that surrounds a planet
Atmosphere
True or False:

2 forces, gravity and updraft
Cold air is _____ (high,low) pressure, while warm air is _____ (high, low) pressure.
high; low
