atmosphere and weather test review
Card Set Information
atmosphere and weather test review
atmosphere weather test review
atmosphere, climate change, weather and meteorology...
Layers of the atmosphere (closest to farthest)
troposphere, stratosphere, mesosphere, thermosphere, exosphere
atmosphere protects us from what?
ultraviolet rays from the sun by blocking and absorbing them
temperature and pressure changes with increasing altitude
zig-zaggin temps (in troposhere, with rising altitude, temperatures drop... stratosphere rising altitude temperatures rise.....)
pressure decreases as altitudes raise
composition of the earth's atmosphere
.03% carbon dioxide
small % of others
most common element in atmosphere
what is a greenhouse gas
gases like methane, chlorofluorocarbons, and carbon dioxide that act as a shield to trap heat in the earth's atmosphere.
What causes greenhouse gases?
human activity such as fossil fuel burning and deforestation (polution)
What is the greenhouse effect?
the rise in temperature that the earth experiences because certain gases trap energy from the sun. Without this, heat would escape back into space.
What is climate change?
an change in global temps/precipitation/wind over time
stages in the water cycle
evaporation, condensation, precipitation, and runoff
the process of a liquid changing into vapor (heat)
the cycle of evaporation and condensation that controls the distribution of the earth's water
process of a vapor changing into a liquid (cooling)
water that falls to the ground in a liquid/solid form (rain, snow, hail...)
precipitation that cannot be absorbed by the ground and moves over the surface
source of all energy on earth
What process causes the winds to blow?
the heating and cooling of air (hot air rises, cool air sinks...) and pressure differences
How does the Coriolis Effect work?
the deflection of a moving mass of water/air to the right in Northern hemisphere and to the left in the southern hemisphere
#1 = The Sun
: causes the water to evaporate
#2= Clouds (condensation)
: process of a vapor changing into a liquid
#3 = Evaporation
: the process of a liquid changing into vapor (heat)
#4 = Precipitation
: water that falls to the ground in a liquid/solid form (rain, snow..)
#5= The Ocean (runoff :p) precipitation that cannot be absorbed by the ground and moves over the surface
What causes the coriolis effect?
the earth's rotation and polar winds
How does density relate to temperature and humidity of air?
humid air= less dense
less humidity=greater density
high density=cool temps
low density=high temps
land breezes and sea breezes
land heats faster than water so during the morning, the warm air rises off the land and is replaced by the cooler air coming off the water.. visa-versa at night (land cools faster than water too...)
what are doldrums?
light winds that persist over equilateral regions of earth
how do clouds form?
saturated (humid) air is cooled below its new point causing water droplets to condense around dust particles in the atmosphere
line drawn on a weather map/chart linking similar temps
lines drawn to indicate regions of similar pressure
boundary between air masses of different temperature/pressure
Answer questions... whats missing?
Circle shows cloud cover
MISSING>>>>upper right=air pressure between 960-1050
lower left= dewpoint
flag=wind direction and wind speed (1/2 flag=5 knots... 1 flag=10 knots)
(should be) directly left=precipitation
amount of water vapor held in the air
water falling from clouds- including rain, snow, sleet, and hail- whose form is determined by air temp
causes moving air and water to turn left in s hemisphere and turn right in n hemisphere due to earth's rotation
stratus cloud that forms when air is cooled to its dew point near the ground
state of the atmosphere at a specific time and place, determined by factors including air pressure, moisture in air, temp, and wind
measure of the amount of moisture held in the air compared with the amount it can hold at a given temp; range from 1% to 100%
layer of the stratosphere with a high concentration of ozone; absorbs most of the sun's harmful ultraviolet radiation
energy transferred by waves or rays
earth's air, which is made up of a thin layer of gases, solids, and liquids; forms a protective layer around the planet and is divided into five distinct layers...
transfer of heat by the flow of material
process in which water vapor changes into a liquid
transfer of energy that occurs when molecules bump into each other
large, severe storm that forms over tropical oceans, has winds of at least 120 km/h and loses power when it reaches land
a type of energy that comes to earth from the sun, can damage skin and cause cancer, and is mostly absorbed by the ozone layer
layer of earth's atmosphere that is closest to the ground, contains 99% of the water vapor and 75% of the atmospheric gases; where clouds and weather occur
studies weather and uses information from doppler radar, weather satellistes, computers and other instruments to make weather maps and provide forecasts
a ___ is used to measure air pressure in units of ____
winds are named by _____
where they come from
high pressure... clockwise, out, down
low pressure... counterclockwise, in, up
weather brought by a low
warm and wet... precipitation
weather brought by a high
cool and dry... clear
