What is true about the melting of permafrost?

• The melting of permafrost releases greenhouse gasses, which increases warming.

• The melting of permafrost helps to regulate and cool down the air temperature in the arctic.

• The melting of permafrost has no affect on anything.

• The permafrost is a lie.

What is one of the main reasons for sea level rise?

• As water melts, it expands.

• Higher amounts of rainfall into the ocean.

• As water heats up, it expands.

• The ground is sinking down into the ocean.

Although levels of CFCs in the atmosphere are much lower than those of CO2 , CFCs are still potent greenhouse gases because they

• remain in the atmosphere for only a brief time

• lack natural sources

• are much more efficient at absorbing thermal radiation

• are more difficult to remove from smokestacks and tailpipes

Which of the following best describes the mechanism of the greenhouse effect in Earth's atmosphere?

• Infrared radiation from Earth's surface is absorbed by gases in the atmosphere.

• Cosmic radiation from deep space is absorbed by gases in the atmosphere.

• Alpha radiation from the Sun is absorbed by water vapor in the atmosphere.

• Ultraviolet radiation from the Sun is absorbed by ozone gas in the stratosphere.
