GEOS 01/19 acid rains, waves

acid rain

any form of precipitation w ph lower than 5.0

any dry acidic particles that precipitate

dissolves certain rocks, change soil/water chemistry

where natural acid rain occurs

downwind of volcanic eruptions

where anthropogenic acid rain occurs

industrial areas

main constituents of acid rain

water

nitric acid

sulfuric acid

radiant energy emitted in

form of electromagnetic waves

radiant energy emitted by

all objects with temp above absolute zero

electromagnetic spectrum

entire wavelength range of electromagnetic energy

sun emits primarily what

shortwave radiation

near infrared, cant feel

earth emits primarily what

longwave radiation

mainly thermal infrared, can see/feel

infrared

can detect

cant see or feel

99% of suns energy emissions (3)

UV

visible light

infrared

earth does what to shortwave solar radiation

absorbs and emits as thermal infrared/sensible heat

waves, 2 principles

wein’s law

stefan-boltzmann law

Wein’s law

hotter objects emit shorter wavelengths than cooler ones

Stefan-Boltzmann law

hotter objects emit more energy than cooler ones

absolute temp of object related to amount of radiation it emits

insolation

rate of incoming solar radiation

measured in W/m²

Blackbody radiator

theoretical perfect emitter of radiation

emits exactly whats absorbed
