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
