Ozone Holes Appear In Polar Regions During Springtime When Ozone-Destroying
Decomposed by chlorine atoms
Ozone molecules
Vertical sunlight
Equatorial regions
Trade winds, westerlies and polar easterlies
Prevailing winds
A greenhouse gas added to the atmosphere when fossil fuels are burned
CO2
Winds push warm water eastward in the Pacific Ocean
El Niño
International limits on CFC production to protect the ozone layer
Montreal protocol
Result of high UV radiation at earths surface
DNA damage
Process by which the atmosphere traps heat radiated up from earths surface
Greenhouse effect
Water is cooler than usual in the eastern Pacific Ocean
La Niña
Caused by wind and influenced by earths rotation
Surface ocean currents
Weather is a regions ..
Atmospheric conditions on a given day
As cold air sinks..
It compresses and warms
International agreement to limit CFC production
Montreal protocol
Destroyed by CFCs
Stratospheric zone
Caused by wind and influenced by earths rotation
Surface ocean currents
Increases when fossil fuels are burned
Atmospheric CO2
Low-angle sunlight
Winter
Winds push warm water eastward in the Pacific Ocean
El Niño
Heat trapped by atmosphere near earths surface
Greenhouse effect
Potential result of high UV radiation at earths surface
DNA damage
Water is cooler than usual in the eastern Pacific Ocean
La Niña
Trade winds, westerlies and polar easterlies
Prevailing winds
Climate in a region is
The long term prevailing atmospheric conditions
Rain frequently results whenever
Warm, moist air rises
Latitude strongly influences climate because _____ solar energy falls on areas that are closer to the equator than to the poles
More
An important property of air circulation is
Cold air is denser than warm air
Which gas is most responsible for the greenhouse effect
Water vapor
Which reduces CO2 in the atmosphere ?
All of the above
Phytoplankton
Tropical rain forest
Oceans
During summer, sunlight in the northern hemisphere shines
More directly for long days
Ozone layer in the stratosphere
Absorbs UV light
Ozone holes appear in polar regions during springtime when ozone destroying
Chlorine atoms are released from polar stratospheric clouds
Once in the atmosphere, CFC's
Persist and continue to destroy ozone for decades
La Niña is the ___ phase of the El Niño southern oscillation (ENSO) cycle
Cold
The average global temperature has ___ during the 20th century
Risen some years and fallen other years but has increased overall
Elevation is a factor in climate because under most conditions..
Temperature falls as elevation increases
Seasonal changes in daylight hours and climatic conditions are caused by
The 23.5 tilt of earths axis
The ozone layer protects living organisms by
Blocking solar ultraviolet (UV) radiation
Ozone holes appear in polar regions during springtime when ozone destroying
Chlorine atoms are released from polar stratospheric clouds
Though CFC production has been curtailed, the threat to upper atmospheric ozone continues because CFCs
Persist and continue to destroy ozone for decades
This does not reduce CO2 in the atmosphere
Animal respiration
A continues record of annual average atmospheric CO2 concentrations from Mauna Loa, Hawaii Revels
A steady increase since 1958
This would not be a consequence of a rise in global temperature
Increased polar ice mass
The belt of prevailing winds that is produced between 30• & 60• south latitudes is called
Westerlies
This statement is true about El Niño
El Niño produces winds in the western
Polar stratospheric clouds convert the products of CFCs into
Molecular chlorine
Not an adverse effect of high levels of ultraviolet light
Increase amount of carbon dioxide in the atmosphere
What season does carbon dioxide in the atmosphere decrease as a result of natural processes?
Summer
Greenhouse gas
All of the above
CO2
Water vapor
Methane
Not a source of Methane
Fertilizer
The average global temperature increased by how many degrees celsius during the 20th century
0.6 •C
This country decided not to joint the Kyoto protocol
