Changes in Earthʹs orbital configuration may lead to warming temperatures.These warming temperatures,in turn,may lead to the release of both CO₂ and CH₄.Increases in these gases may further warm the planet.This is an example of a A)positive feedback loop. B)negative feedback loop. C)neither a positive or negative feedback loop.

Question

Quizplus · Accepted Answer

The cycle described in the scenario represents a positive feedback loop. The initial warming caused by changes in Earth's orbital configuration leads to the release of CO2 and CH4, which are both greenhouse gases that trap heat in the atmosphere, leading to further warming. This continues in a cyclical fashion, with each increase in temperature leading to further release of these gases and further warming.
