1.
thin layer of gas surrounding the earth and is held there by gravity
2.
all weather events occur in this layer of the atmosphere
3.
contains the ozone shield in this layer of the atmosphere
4.
enough friction to break up small meteores, lowest measurable temperature in this layer of the atmosphere
5.
thickest layer of atmosphere, auroras happen here
6.
very thin layer of the atmosphere, can not measure temperature
7.
Absorbs UV radiation coming from the sun
8.
this air sinks because it is more dense (warm or cold)
9.
this air rises because it is less dense and can hold more water vapor (warm or cold)
10.
short term local variations of temp. and precipitation
11.
long term pattern of weather in an area (over decades or centuries!)
12.
Phases of warm and cool climate across the South Pacific Ocean that disrupts air circulation in the tropics
