Which feedback loop can amplify the effects of global warming?a.Feedback inhibitionb.Positive feedbackc.Albedo feedbackd.Negative feedback

Which of the following correctly explains a positive climate feedback loop found in the Arctic?A.Increased melting of permafrost increases Earth’s ability to absorb methane gas, which decreases greenhouse warming and decreases the melting of permafrost.B.Increased global temperatures lead to decreased sea ice coverage and decreased albedo, which further increases global temperatures.C.Increased evaporation and cloud formation decreases the amount of solar energy reaching the surface of Earth, which leads to cooler temperatures at the surface and decreased evaporation and cloud formation.D.Increased precipitation increases the size of high albedo snowpack in polar regions, which leads to increased habitat for Arctic organisms such as polar bears.

Construct an explanation for how feedback loops affect Earth. OR Communicate how different spheres are involved in the example of ice-albedo feedback. You may choose to write or draw your response.

Which type of feedback loop acts to resist change in natural systems, thereby enhancing system stability and promoting conditions favorable for life?Negative feedbackPositive feedback

Draw a feedback loop describing the effect of climate change on permafrost

An example of a positive feedback loop is:Group of answer choices Formation of a blood clotShivering due to muscle contraction in case of cold temperatureIncrease breathing after exercise to bring the blood oxygen level back up to normal.Maintenance of body temperature by sweating in hot summer.
