Earth atmosphere is important to living things because it ................
contains dust and other particles
is very thin compared to the size of Earth
provides all the gases that living things need to survive
maintains a constant relative humidity
Earth rotation makes global winds curve. This is called the ................
convection effect
global effect
Coriolis effect
rotational effect
A missile lunched due south in the Northern Hemisphere will be deflected toward:
east.
west.
At what latitude and during what season is the daily-averaged insolation at the top of the atmosphere the greatest?
Equator at Equinox
Equator on Jan. 5
South pole on Dec. 21
North pole on June 21
Cyclones:
experience Coriolis effects that deflect air to the right in the Southern Hemisphere.
are associated with supergeostrophic winds.
are typically regions of fair weather.
are associated with low-pressure systems.
A geostrophic wind:
flows perpendicular to the pressure gradient force.
is usually not affected by the Coriolis force.
follows the pressure gradient force.
The radiation emitted by Earth:
had its origin in radioactive elements in the earths interior.
is primarily absorbed by the atmosphere.
has little effect on the earths energy budget.
is in the form of radio waves.
Volcanic outgassing:
has had little effect on the earths atmosphere.
created the earths first atmosphere.
emits very little carbon dioxide.
emits large amounts of water vapor.
Anticy clones:
have clockwise winds in the Northern Hemisphere.
have air spiraling into them near the surface.
are associated with subgeostrophic winds.
If the air temperature remains constant, evaporating water into the air will ……………….. the dew point and …………………. the relative humidity.
decrease, increase.
increase, increase.
increase, decrease.
decrease, decrease.
As you rise upwards in the atmosphere air pressure ................
increases
decreases
doesnt changefirst increases, then decreases
The atmospheric window:
is a local phenomenon similar to the ozone hole that opens over Antarctica in winter.
is located at a band of wavelengths between 0.1 and 0.4 micrometers.
allows certain wavelengths of longwave radiation to pass through the atmosphere.
Specific humidity:
is a useful measure for comparing water vapor at two different locations.
is the same as the relative humidity.
changes as a given mass of air expands
The Coriolis force:
affects the direction of motion.
is caused by pressure gradient forces.
affects the speed of motion.
is constant.
The solar constant:
is higher for Earth than for Mars.
varies inversely with the fourth power of an objects distance from the Suns surface.
is the same throughout the solar system.
Of the following planets, which has the most massive atmosphere?
Mars
Earth
Venus
The maximum concentrations of ozone are found in the:
stratosphere.
mesosphere.
troposphere.
ionosphere.
Geostrophic flow:
occurs in atmospheric levels with substantial friction.
occurs when the pressure gradient force equals the Coriolis force.
can occur in all levels of the atmosphere.
A greenhouse works because:
the windows of the greenhouse only allow green light wavelengths to pass through.
of the difference in the solar constant.
all greenhouses face south and into the maximum angle of solar energy.
short wave lengths of energy pass through the glass but longer ones cant.
If object A is at 400 K, and object B is at 800 K, then the radiation intensity of object A will be this amount of that the radiation intensity of object B:
one-half.
one-fourth.
one-sixteenth.
one-eighth.
