Earth's Energy Budget and the Greenhouse Effect

Earth receives its energy from the sun in the form of ____________________ radiation and the Earth releases the heat it received in the form of ________________ radiation

• Gamma and Radio

• Visible and Ultraviolet

• Longwave and Shortwave

• Shortwave and Longwave

*When solar energy hits the earth*

• it can be either reflected or absorbed by the atmosphere and/or the surface

• it is all absorbed by the atmosphere and the surface

• it is mostly reflected by the atmosphere and the surface

• it cannot affect processes that occur on earth

The primary difference between long wave and shortwave radiation is

• longwave radiation is more energetic than shortwave

• shortwave radiation is released from the earth as heat and longwave radiation comes from the sun

• longwave radiation in less energetic than shortwave radiation

• shortwave radiation is able to be absorbed by greenhouse gases and longwave radiation can not be absorbed by greenhouse gases

Describe what scientists mean when they say Earth’s energy budget.

• We should spend way more money on taking care of Earth.

• The balance between the energy humans consume and the pollution humans emit.

• The balance between the energy that Earth receives from the sun and the energy that Earth re-emits/reflects back.

• The balance between the energy coming in from the sun and the energy that humans need to survive.

*Of the radiation that travels from the sun to the troposphere, what percentage is reflected by clouds?*

*Of the radiation that travels from the sun to the troposphere, what percentage is absorbed by land and water and converted into heat?*

*What percentage of solar radiation is absorbed by the atmosphere and clouds?*

• 5%

• 20%

• 30%

• 50%

The greenhouse effect is caused by

• more heat arriving at the earth from the sun than the earth emits out into space

• the earth releasing more heat at night than it receives during the day

• certain gases in the atmosphere that are trapping heat released by the earth.

• the varying difference in the distance we are from the sun throughout the year.

Without a greenhouse effect happening on earth, our planet would

• be too warm to sustain human life

• be too cold to sustain human life

• not have enough oxygen would be present in the atmosphere to sustain human life

• have too much carbon dioxide would be present in the atmosphere to sustain human life
