Climate Systems and Climate Change

The warming of the atmosphere by the trapping of heat is called

• evaporation

• condensation

• the greenhouse effect

• radiation

What is the greenhouse effect?

• The warming of a planet due to trapped radiation (heat).

• The cooling of Earth due to air pollution.

• The heating of a solid, such as a rock.

• The warming of a planet due to trapped air pollution

How is Earth a greenhouse?

• Earth's atmosphere does the same thing as the greenhouse.
• Carbon Dioxide, a gas in Earth's atmosphere, does what the roof of a greenhouse does. 
• The Sun shines through the atmosphere, warming the Earth's surface.
• All of the above

Without the Greenhouse Effect the Earth would be

• warm 
• cold
• dead

The main human activity that releases greenhouse gases is...

• using bottled water

• burning fossil fuels (coal, oil, natural gas)

• texting on cellphones

• eating meat

In the past, refrigerators and air conditioners were all sources of a greenhouse gas known as

• carbon dioxide

• methane

• chlorofluorocarbon (CFC)

• nitrous oxide

Which greenhouse gas comes from livestock and other agricultural practices and decaying matter in landfills?

• Carbon Dioxide

• Methane

• Water Vapor

• CFCs

• Nitrous Oxide

Certain gases in the atmosphere – water vapor, carbon dioxide, methane and nitrous oxide – help maintain the Earth’s temperatures and climate. These are called: __________ .

• ozone gases

• solar gases

• greenhouse gases

• stomach gases

Which of the following natural events is NOT a source of carbon dioxide?

• Wildfire

• Decomposing plants and animals

• Volcanic eruption

• Earthquake

Consequences of climate change include:

• Stronger hurricanes
• Increased flooding
• Frequent droughts
• All of the above
