Oldest surface on Earth discovered

Earth's surface is mostly fresh in geologic terms.

Weathering — wind and water, freezing and thawing — takes its toll, and longer-term changes caused by volcanic activity and sliding crustal plates, known as tectonic activity, fold today's ground into tomorrow's interior.

The constant makeover of the planet is typically fastest in the mountains, slower in the tectonically inactive deserts.

A new study of ancient "desert pavement" in Israel's Negev Desert finds a vast region that's been sitting there exposed, pretty much as-is, for about 1.8 million years, according to Ari Matmon and colleagues at Hebrew University of Jerusalem.

There are parts of the Canadian shield that are 3 billion years old.

I think you are right about the continuously exposed serface.

[Rebelbase]

The Canadian Shield is deeply saddened.

[decimon]

1.8 million years isn’t that long. Seems like I’ve read that the oldest known surface is in central africa at over a billion years.

Course with scientists you never know how they classify various things. It could be that this is the oldest known continuously exposed surface.

And these articles are concise renditions by third parties of what must have been lengthy research.

Is there a difference?

I don’t believe so, though I have not seen her posterior and I plan to keep it that way.

[Prophet in the wilderness]

The Negev Desert is what is referred to in the Bible as the Wilderness.

[null and void]

Uh. Do you happen to live there?

Just askin’...

[Prophet in the wilderness]

Not really, ... but, most people when they think of the wilderness what comes to mind is a forest, or the plains ... but, that’s what I have learned from bible teachers that the wilderness that David was in was the Negev desert.
