earth space

what are the most important elements of weather and climate that we measure?

temperature, humidity, cloudiness, precipitation(rain,snow), air pressure, wind speed and direction

water covers --- percent of the northern hemisphere

61

water covers --- percent of the southern hemisphere

81

abiotic cooling

cooling due to decrease in density

isotherms

Lines joining places that have the same temperature

albedo

Ability of a surface to reflect light

trophoshere

bottom layer, temp decreases with altitude due to adiatic cooling, tropopause

stratosphere

second layer, temp increase at top due to ozone layer taking in UV radiation. statopause

mesosphere

3rd layer, least studied, mesopause, temp decreases. No well defined upper limit

exosphere

exit to space,

altitude increases, pressure ---

decreases

Altitude decreases, pressure...

increases

what causes seasons?

The tilt of the Earth's axis(changes by day) (axis inclined 23.5)

the earth is facing the -- at different angles each day

sun

heat is transferred from ---

warmer to cooler objects

conduction

through molecular activity

convections

mass kovement within a substance

radiation

velocity 300,000 k per second (fire)

reflection

throwing back by a body or surface of light without absorbing

scattering

reflection of light in all directions

absorption

the process or action by which one thing absorbs or is absorbed by another.

--- percent of radiation (visible light)is abosrbed by ground

50
