Why in the news?

Scientists confirm there are 40 huge craters at the bottom of Lake Michigan.
Researchers recently surveyed the bottom of Lake Michigan after spotting strange circles on the lakebed in 2022. New observations show the circles are craters, but how they formed remains unclear.

About Lake Michigan:

It is the third largest of the five Great Lakes of North America and the only one lying wholly within the United States.
It is the fourth largest freshwater lake and the fifth largest lake in the world ranked by surface area.
It is 517 km long (north to south); it has a maximum width of 190 km.
It is connected directly to Lake Huron, into which it drains, through the broad Straits of Mackinac.
- This hydrologic connection through the Straits keeps the water levels of the two lakes in equilibrium, causing them to behave in many ways as though they are one lake.
Water flows into Lake Michigan from several rivers, including the Fox-Wolf, the Grand, the St. Joseph, and the Kalamazoo rivers.
It boasts a variety of natural habitats, including tallgrass prairies, wide savannas, and the world’s largest freshwater sand dunes.
It hosts a wealth of plant and animal species, many of which are rare or endangered (such as the Hine’s Emerald Dragonfly and the Dwarf Lake Iris).

Crater:

It is a bowl-shaped depression, or hollowed-out area, produced by the impact of a meteorite, volcanic activity, or an explosion.
Craters produced by the collision of a meteorite with Earth (or another planet or moon) are called impact craters.
