Climate Feedback Mechanisms
1.
In Earth Science, feedback mechanisms involve
- the biosphere.
- the lithosphere.
- the hydrosphere.
- the atmosphere.
- all of the above.
2.
Feedback loops are mechanisms that involve variables.
- simple; a few
- simple; many
- complex; a few
- complex; many
3.
A negative feedback loop change and a positive feedback loop change.
- decelerates; accelerates
- accelerates; decelerates
4.
Which is an example of a negative feedback loop?
- global warming
- biological homeostasis
- exponential population growth
5.
Negative feedback loops tend to the environment and positive feedback loops tend to environmental problems.
- stabilize; decrease
- stabilize; increase
- destabilize; decrease
- destabilize; increase
6.
Is the scenario described below an example or a positive or negative feedback loop?
melting polar ice decreases solar energy reflection resulting in warming temperatures and more ice melt
melting polar ice decreases solar energy reflection resulting in warming temperatures and more ice melt
- positive
- negative
7.
Is the scenario described below an example or a positive or negative feedback loop?
increased growth in vegetation also increases evaporation and decreases water runoff and infiltration resulting in more precipitation and plant growth
increased growth in vegetation also increases evaporation and decreases water runoff and infiltration resulting in more precipitation and plant growth
- positive
- negative
8.
Is the scenario described below an example or a positive or negative feedback loop?
increase in evaporation creates more clouds that reflect more light away from Earth resulting in a decrease in temperatures and evaporation
increase in evaporation creates more clouds that reflect more light away from Earth resulting in a decrease in temperatures and evaporation
- positive
- negative
9.
Is the scenario described below an example or a positive or negative feedback loop?
melting permafrost releases methane into the atmosphere resulting in increasing global temperatures
melting permafrost releases methane into the atmosphere resulting in increasing global temperatures
- positive
- negative
10.
The diagram represents the carbon cycle. Describe how Earth naturally balances carbon and carbon dioxide levels. Next, describe the role of human fossil fuel consumption and how this impacts the carbon cycle.
