Answer: Lakes
Step-by-step explanation:
Minnesota says that it has over 11,000 lakes of 10 acres or more with Otter Tail County having 1,048 lakes alone making it the country with the highest number of lakes in the country.
These lakes were formed thousands of years ago when glaciers kept moving across the surface of Minnesota. One way lakes were made was when the glaciers made holes in the ground, ice chucks fell into them that eventually melted and became lakes.
