As permafrost thaws,increased microbial activity in the soils results in the release of more carbon to the atmosphere.More carbon in the atmosphere accelerated the greenhouse effect.As temperatures increase further,more carbon can enter the atmosphere,causing temperatures to increase even more.This is an example of a(n)
A)positive feedback loop.
B)negative feedback loop.
C)threshold.
D)static state.
E)equilibrium state.

Question

Quizplus · Accepted Answer

The scenario described shows a positive feedback loop, where increased temperatures lead to the release of more carbon, which in turn further increases temperatures leading to more carbon being released. This cycle is self-reinforcing and can continue until other factors intervene.
