3.1 Composition/Structure of the Atmosphere
What percent (more or less) of the atmosphere is oxygen?
21%
What is radiation?
Transmission/emission of energy in the form of waves through space or a material medium
What is air pressure?
The mass of the atmosphere exerting a compressive force on bodies due to the force of gravity
What is the lowest layer of the Earth's atmosphere?
Troposphere
True or False: Shortwave radiation contains little energy
False. It contains a lot of energy which makes it have a lot of movement (and thus short waves) which contributes to it being visible
Air flows from the high pressure system to the low pressure system
Which two atmospheric layers lie above and below the stratopause?
Stratosphere & Mesosphere
Which type of UV ray is the most damaging?
UV-C
True or False: Air pressure decreases with a decrease in altitude
False. Air pressure decreases with an INCREASE in altitude (inversely proportional)
What is the name of the middle layer of the atmosphere?
Mesosphere
What does the unequal heating of land and water cause?
Land and Sea Breezes
Between weather and climate which is the one we "expect"?
Climate
What is the outermost layer of the atmosphere?
Exosphere
Which has a higher albedo: water or land?
water
Weather is caused by _______ changes in the _________.
short-term; atmosphere
