The Biosphere

Kara uses a model that shows slight changes to Earth's motion through space over many thousands of years. This model helps explain long-term climate change due to what variable?

• volcanic activity

• meteor or asteroid strikes

• ocean circulation

• carbon dioxide levels in the atmosphere

• input of solar energy

Lionel uses a model that includes the atmosphere and sunlight to predict Earth's temperatures. In this model, why does increasing the levels of carbon dioxide in the atmosphere cause temperatures to increase?

• Sunlight passes through carbon dioxide

• Sunlight is absorbed by carbon dioxide

• Heat is trapped by carbon dioxide

• Carbon dioxide generates heat

• Carbon dioxide reacts with water to release heat.

Scientists have concluded that human activities are affecting the atmosphere and causing rapid climate change on a global scale. Which statement provides the strongest evidence that these changes to global climate are NOT the result of natural causes, such as variations in Earth's orbit?

• Until recently, Earth's climate had remained relatively constant.

• Variations in Earth's orbit cannot be measured precisely.

• Variations in Earth's orbit would affect climate only minimally.

• Earth's climate depends mostly on the output of the sun.

• Variations in Earth's orbit occur gradually over 100,000 years

Greenhouse gases include carbon dioxide and methane. How do greenhouse gases act to increase air temperatures near Earth's surface?

• They transmit visible light that enters the atmosphere

• They trap heat that is radiated from the surface

• They reflect that enters the atmosphere

• They emit heat when they undergo chemical reactions.
