humidity
water vapour in air
absolute humidity
mac amount of H2O avoir un air at a given temperature
relative humidity
a percentage of the absolute humidity
heating land/water
land absorbs and loses fast
water absorbs and loses very slow
layers of the atmosphere
troposphere, stratosphere, mesosphere, thermosphere
heat transfer
conduction: direct contact
convection: non direct contact
radiation: no contact
solar constant
1367 KJ/m2
1m2 of energy perpendicular to the sun
thermodynamics
heat transfer
Q=MC delta T
Q
quantity of heat
M
mass
C
how much energy is needed to move one gram of substance up or down
delta T
change in temperature
final - initial
Lv and Lf and gas solid liquid
LV: 2269 Lf: 333 solid: 2.1 liquid:4.18 gas: 2.2
heating land/ water
land: absorbs and loses fast
water: absorbs/loses slow
heating air
hawt radiates off of the ground to heat air (air moves and creates wind)
-earth roared and caused air to create wind patterns
troposphere
altitude: 10 - 11 km up = 39000fr
temperature: 20° to -57°
sig factors: all living things are here
stratosphere
altitude: 10-59k
temperature: -57° to -20°
sig factors: O3 ozone
mesosphere
altitude: 50-90k
temperature: -20° to -90°
sig factors: meteors
thermosphere
altitude: 90 - lots
temperature: -90° to 600°
sig factors: auroras/ northern and southern lights
-
wave lengths
the peaks are called crests and the whisk are called troughs. inbetween those is the wave length
name the wavelengths
radio waves microwaves infrared radiation visible light ultraviolet radiation xrays gamma rays
