PBIO 1000- EXAM 2 QUESTIONS WITH VERIFIED
ANSWERS
Four major green house gases - Answers - 1. Carbon
2. Methane
3. Nitrous oxide
4. Fluorinated Gases
GWP - Answers - measurement of how long certain gas remains in the atmosphere and
how it absorbs energy
Describe how carbon dioxide cycles in the biosphere and its effects on the ocean -
Answers - The transfer of carbon dioxide to the oceans causes the surface oceans to
acidify
Describe how water vapor acts to increase the warming caused by other GHG's -
Answers - the more water vapor in the atmosphere, the hotter it becomes. (water vapor
feedback loop)
Carbon Sequestration - Answers - CO2 is pulled from the atmosphere and stored for a
long period of time
describe the importance of forest resources in mitigating climate change - Answers -
Forest resources provide new opportunities for forest landowners and managers to
enhance forest stewardship in addition to reducing greenhouse gas emissions through
forest carbon sequestration
Discuss the role that peat moss plays in carbon sequestration on a global scale -
Answers - important for water management - peat moss holds in carbon
What is the best way to maintain stored carbon and reduce greenhouse gas emissions?
- Answers - Manage forests intensely to increase growth rate
Agroforestry - Answers - where big trees are planted next to small bushes
benefits of agroforestry - Answers - more plant diversity, holds multiple nitches, greater
biodiversity
Benefits of Chagga Home Gardens - Answers - -carries over 100 plant species
-high diversity
-sustains natural resources
