Mаny lаkes in the nоrthern midwest experience а prоcess called inversiоn where in the fall, very cold evenings chill the top layer of water, which increases its density. The more dense water sinks past the warmer mid and bottom layers, thereby lifting the middle layer of the lake. This process will continue on each evening that the temperatures are drastically colder than those in the day. This causes water to appear murky, yet increases oxygen content, which is helpful for the ecosystem of the lake. Which of the follow terms best describes what is happening.
