Air Composition, Pressure, & Layers
Question | Answer |
---|---|
78% of Earth's atmosphere | nitrogen |
The force of the air pushing down on an area of Earth's surface | air pressure |
as altitude increases, air pressure __________________. | decreases |
trace gases are ......... | 1% of Earth's atmosphere (argon, CO2, water vapor, etc....) |
21% of Earth's atmopshere | oxygen |
tool to measure air pressure | barometer |
tool to measure thermal air temperature | thermometer |
The layers of Earth's atmosphere are separated by... | differences in temperature change |
Layer of the atmopshere where weather occurs | troposphere |
meteors mainly burn up in this layer if Earth's atmosphere | mesosphere |
contains the Ozone layer | stratosphere |
height above sea level | altitude |
lines on a weather map connecting areas of equal air pressure | isobars |
air pressure associated with sunny and nice weather | high pressure |
air pressure associated with cloudy and rainy weather | low pressure |
three (3) standard air pressures | 1013mb; 29.92" of mercury; 14.7psi |
three ways in which the Earth's atmosphere protects life on the planet. | 1. controls Earth temperatures 2. blocks harmful solar radiation (UV) 3. prevents most meteor impacts |
layers of the atmosphere where satellites and the ISS can be found. | thermosphere |
only gas that can flucuate back and forth from Earth's geosphere to its atmosphere | water vapor (water cycle) |
Air pressure decreases as altitude ________________ | increases |
