Which mechanism causes a kettle lake to transition into a bog over extended periods?

💡 Explanation

When kettle lakes receive continuous organic matter washed in from surrounding areas (allochthonous imputs), eutrophication begins, leading to sediment accumulation and eventual bog formation. Therefore vegetation succession occurs because organic accumulation causes anoxia, preventing decomposition making a marsh. This, rather than warming, upwelling, or dissolving carbonate rock, dictates long-term fill-ins.
