!Part C: Climate Change

!1. Whatisthedifferencebetweenweatherandclimate?
2. The Sun radiates energy onto all surfaces of the Earth’s surface. Explain two reasons why the climate at Earth’s poles is colder than the climate at the equator.
3. How do bodies of water affect local temperatures?
4. What does it mean to be Anthropogenic?

6. What is a heat sink?
7. What is a carbon sink?
8. How does deforestation contribute to climate change?
9. If temperatures climb, more H2O(g) will be released from surface water. Why would this create a feedback

loop? What kind of feedback loop would it be? Sketch the feedback loop.
10.Identify one natural phenomena and one human activity known to affect climate.
11.There are many negative effects of power plants that burn fossil fuels such as coal. Choose one alternative

method for generating electrical energy, and list two reasons why this method would be a good choice. 12.Why are the Arctic and Antarctic regions the most likely regions of the planet to show drastic changes caused

by global warming more than any other area?
