How the Great Lakes Were Formed

Superior, Michigan, Huron, Erie, Ontario. These are the Great Lakes that make up the world's largest freshwater system. But how did they come to be? The answer lies with glacial scouring and isostatic rebound. The Niagara Escarpment is also an interesting feature.

Would've been cool to learn how they were formed in a video about how they were formed

Don't worry, land. When I'm under immense pressure I become depressed, too.

Lake Superior and Lake Ontario are deep because they are part of a riff valley formed when the north American continent started to rip apart.

Nice one!
I’ve been to a very large artificial lake I which I recall was amazing, somewhere in the west of the U.S.
Perhaps close to Utah.
I can’t remember what it’s called. It was 27 years.
I think it’s a massive one. Can you think of one?

What do you do with a drunken sailor, as the background music? Is there some significance to that?

Good info in a nice to-the-point presentation.

It's almost like they were formed by some being that knew what they were doing.

Three questions:
How did the glaciers form?
How did the glaciers melt?
I seems like global cooling and global warming to me.
But, what caused this Climate Change?
Asking for a friend.

It’s always fun to listen to someone tell us with absolute authority about something that happened that absolutely no human being witnessed. I’m just grateful real science and engineering doesn’t work that way.

During the ice ages when atmospheric co2 was between 1800-6000 ppm!

The Edmund Fitzgerald went down in Lake Superior.

If true then why is the world’s largest salt mine under Lake Michigan?

Where did all of that salt come from?

It seems to me that the area was once at the bottom of a large ocean that dried up and left its salt deposit behind.

You should ask Ken Ham. His theory makes way more sense

[countryside]

You forgot to mention that a lot of rivers in N.E Wisconsin flow north and NOT south!!

Answer: the lakes were formed by ice melting into water.

[johnpaulmakowski]

Hmmm. Yeah, I don't think so...

Interesting how ppl talk about the “last ice age” without addressing what caused it to recede .. the earth got WARMER. Sound familiar to the hype we hear today? And we’re still in a receding ice age, meaning the earth will continue to get hotter until no ice is left .. all without man’s help 😉 So relax folks

there is no glacier mountains-there is just snow and more snow

[jimknight]

If you are wondering why the great lakes exist why don't you ask God why he created the great lakes. Or it was glaciers that formed those great lakes plus I learned this back in grade school.
