Feedback occurs when the output of a system does not serve as an input.
False
Positive feedback leads to a decrease in output.
False
Negative feedback is a self-regulating process that keeps a system in a relatively constant condition.
True
An increase in output always leads to a decrease in output in a negative feedback system.
False
Feedback can either be positive or negative.
True
Explore the potential negative feedback loops that could mitigate the effects of global warming, including increased vegetation, changed precipitation patterns, and cloud cover. Test your knowledge of the Earth's climate systems and the processes that regulate them.
