chapter 28.1 Flashcards
a layer extending an average of 12 km above earths surface
troposphere
occurs when air temperature increases with altitude and the air becomes stable
temperature inversioin
is a natural process in which certain gases in the atmosphere warm a planet as they absorb and emit infrared radiation
greenhouse effect
how are the earth’s atmospheric separated
based on differences in composition and temperature
what gas makes up the majority of the atmosphere
nitrogen(78%)
what is the second most abundant found in the atmosphere
oxygen(21%)
what is the one percent of gases that make up the atmosphere
trace gases, argon
in the troposphere does the temperature increase or decrease in the altitude
decreases
what are the names of the atmospheric layers starting closed to the surface
troposphere, stratosphere, mesosphere, thermosphere, exosphere
what layers is the ozone layers found in
stratosphere
does the stratosphere does the temperature increases or decreases
increases
within the atmosphere does temperature increase or decrease
decreases
does the thermosphere and the exosphere in pact weather
no
where does 100% of our solar radiation come from
the sun
what percentage of solar radiation is absorbed by earth’s surface
50%
what percent is reflected off of eathes surface
5%
what percentage of radiation is absorbed by particles in the atmosphere
20%
what percentage of solar radiation is reflected back by particles in the atmosphere
25%
what are there basic cloud types
cirrocumulus, altocumulus, and stratus
explain stratus clouds
layered sheet-like clouds and are associated with rain
explain cumulus clouds
are puffy in shape and occur in fair weather
explain cirrus clouds
are wispy, high altitude clouds
what is the processes where the water from the land enters the atmosphere and eventually falls back to the land
the water cycle
what are the steps to the water cycle
evaporation, transpiration, condensation and precipitation runoff
