What is an example of a positive feedback mechanism and an example of a negative-toedback mechanism? Select one of each An example of a negative-feedback mechanism might be global warming increasing the cloud cover on Earth and this cloud cover increasing Earth's albedo and reflecting solar energy back into space decreasing solar radiation absorption by the atmosphere. An example of a negative feedback mechanism might be that as global warming increases, the rate at which organic matter is decomposed quickens, releasing more carbon dioxide into the atmosphere. This added carbon dioxide increases global warming, which increases the rate at which organic material decomposes. An example of a positive feedback mechanism might be that when global warming increases, the rate of photosynthesis in plants increases, absorbing more carbon dioxide from the atmosphere, thus reducing the greenhouse effect and global warming An example of a negative feedback mechanism might be that as global warming increases, permafrost molts, producing waterlogged soil above frozen ground This leads to the release of the greenhouse gas methane, which increases global warming, leading to the melting of more permafrost An example of a positive-toedback mechanism might be that when global warming increases, the perennial ice cover near Antarctica declinos, which results in a decrease in albedo, causing less solar radiation to be reflected.
