Unit 2 - Climate Change Review

The Greenhouse Effect __________________________.

• Traps all of the heat from the Sun

• Repels sunlight away from the atmosphere

• Traps some heat and releases some heat back to space

• only works in the summer months

Human activities are __________________ the levels of the greenhouse gases in the atmosphere.

• Increasing

• Decreasing

• maintaining

• fluctuating

Natural causes of climate change include all of the following except:

• movement of the continents

• major volcanic eruptions
