|
Greenhouse gases
|
CO2, water vapor, methane, nitrous oxide, ozone
|
|
|
1st layer of atmosphere
|
10 KM Troposphere
Temp decreases as you go up |
|
|
2nd layer
|
50 KM stratosphere
temp increases |
|
|
3rd layer
|
80 km mesosphere
temp decreases |
|
|
4th layer
|
up to 600 KM Thermosphere
**** increases to like 1000 Celsius in this ma |
|
|
natural forcing
|
temperature change due to solar variations and volcanic activity
|
|
|
anthropogenic forcing
|
temp change due to greenhouse gases and sulfate aerosols
|
|
|
Newton's theory of light
|
a beam of light is composed of a stream of millions of tiny particles
|
|
|
Christian Huygens' Theory of Light
|
light can be interpreted as a wave
|
|
|
1789 Thomas Young Experiment
|
passed a beam of light through 2 side by side slits to see the other side and it looked funny as snizz cuz Thomas Young was a huge scroner.
light beams interfere --> constructive and destructive interference |
|
|
1887 Michelson-Morley Experiment
|
demonstrated aether didn't exist and light travels through vacuum
|
|
|
Aether
|
element people used to believe light propagated itself as a wave through
|
|
|
James Clark Maxwell
|
mid 1800s showed light was an electromagnetic wave with a particular range of wave lengths
|
|
|
Infrared radiation
|
wavelengths longer than red
|
|
|
ultraviolet radiation
|
wavelengths shorter than violet light
|
|
|
radio waves
|
very long, inch to mile
|
|
|
microwaves
|
between infrared and short wave radio
perfect length and frequency to shake water molecules which generates heat |
|
|
x rays
|
very short wave lengths
can easily pass through matter |
|
|
gamma rays
|
smallest length
can easily pass through matter |
|
|
Fracking
|
injection of water, sand, and chemicals into horizontally drilled wells so tat natural gas will flow into the cracks created by the injection
|
|
|
Problems with fracking
|
Possible earthquake cause especially due to disposal, uses lots of fresh water, can contaminate drinking water, kicks mad dust up, lots of truck traffic
|
|
|
Elastic Rebound Theory
|
created by HF Reid, describes 2 rocks pushing together, building up strain, then slipping (earthquake), then snaps back into original stress free shape. the snapping back motion is the elastic rebound
