Giant Crack in Africa Will Create a New Ocean

....A 35-mile rift in the desert of Ethiopia will likely become a new ocean eventually, researchers now confirm.

The crack, 20 feet wide in spots, opened in 2005 and some geologists believed then that it would spawn a new ocean. But that view was controversial, and the rift had not been well studied.

A new study involving an international team of scientists and reported in the journal Geophysical Research Letters finds the processes creating the rift are nearly identical to what goes on at the bottom of oceans, further indication a sea is in the region's future.

The same rift activity is slowly parting the Red Sea, too.

Using newly gathered seismic data from 2005, researchers reconstructed the event to show the rift tore open along its entire 35-mile length in just days. Dabbahu, a volcano at the northern end of the rift, erupted first, then magma pushed up through the middle of the rift area and began "unzipping" the rift in both directions, the researchers explained in a statement today....

I concur with my kids that the great lakes are as much oceans as the other large bodies of water.

Earth-fart zone.

There's a sequence on that rift in the "Planet Earth" documentary. Looks like it was shot on Venus.

There will soon be a new sea in the world, too, as soon as the U. S. and Canada sign the agreement.

Oceans are large bodies of salt water. They sit on oceanic plates (excepting shallows around the continents) which are generally basaltic. The great lakes are made of fresh water and sit on continental plates which are generally granitic.

i take it you're not a kid?



From the shore, it looks the same. to a kid. and that's about as much as it matters... in life.

No. That's about as much as it matters to someone who is not willing to inquire further.

Teach your kids to ask questions and to think about the limits and legitimacy of the answers they're given.

My young nephews annoy the heck out of me with the "why" game. I love every minute of it and encourage them. When we get to the point where I don't know the answer, we look it up together and talk about the different answers we get from various sources.

Good luck trying to define a difference between a pond and a lake, too.

the one across from me is a pond on some state maps / surveys and a lake on others.

Ponds are small. Lakes are big. Duh!

You can swim across a pond but not necessarily across a lake.
I asked a geologist once what defined a mountain. He said if your ears pop when traveling over, it's a mountain; if not it's a hill.

Mountains have snow caps and billy goats. Hills do not

Would have been nice if the story included a locator map.

As for the Great Lakes, according to "How the Earth was Made", they're only about 12K years old. That really surprised me; I always assumed they were millions of years old.

Well, that is the current incarnation of the Great Lakes as left behind by the last glacial period. There were lakes in the same region left behind by previous glaciations, but not all the geological evidence is available to give any precise map of their configuration. The bottom of Superior basin definitely predates the last glacial period, so there would have been some body of water there before.

The show said they are based on an ancient set of rivers which were carved out by the ice into the current lakes. I'm not sure if they mentioned multiple ice ages.

Many millions of years ago, all of what is currently Michigan and the surrounding Great Lakes was a big (salt water) sea.
