Great Lakes provide fresh water, and some salt

# data[].attributes.body
The Niagara Falls erodes. In the Niagara Falls, there are two types of rock. One is a weaker limestone sedimentary rock, and another is the harder, dense sedimentary rock on the top. These layers are surrounding the whole waterfall. Because of the rushing water that flows, the weaker limestone is eroded and caves in, like shown in the video.

The Great Lakes provide fresh water

# data[].attributes.body
Great lakes provide 10 percent of the water we drink for North America.

# data[].attributes.body
I think the salt content in the water is slowly collecting onto the salt areas, and the salt that is naturally forming onto the mines is keeping it from dissolving

# data[].attributes.body

The weaker rocks supporting the stronger upper layers of rock are eroded by the flowing water, which then causes the upper rock to be eroded, so the falls will continue to be pushed farther and farther back.

# data[].attributes.body
The salt is covered by other, stronger rock, and as it is being dissolved more salt is forming very slowly. Despite this the salt is still slowly dissolving.

# data[].attributes.body
We know that the Great Lakes used to be an inland sea because the Great Lakes have limestone walls that suggest animals lived inside of it.

# data[].attributes.body
The moving water carries the rocks which happens over and over again, over time the rocks will be moved away and broken down to weaker rocks.

# data[].attributes.body
We know that the Great Lakes used to be an inland sea because there is limestone on the land, and I know that limestone can have coral fossils which come from underwater, which suggests that the place was once beneath water.

# data[].attributes.body
We know this, because of the limestone around the edges of the lake (limestone is made of dead sea creatures).

# data[].attributes.body
I think the minerals being mined underneath Lake Michigan and Lake Huron keeps the minerals from dissolving because the chemicals could of moved on to the lakes which the salts are already being dissolved.
