What is a region formed by ancient rock?
A craton
Which is a part of the North American craton?

Only a portion of the North American craton is visible because the rest has been?
buried beneath other rocks
What is a craton and what is a kimberlite pipe and how are they linked to the discovery of the diamond?
A craton is 'an old and stable part of the lithosphere' -- the earth's crust. One class of inclusions in the formation of the earth's crust when subductions of crust were folded into the deep, kimberlite diamond areas that lie about 150-450 K below the surface. Diamonds as we know them are exploded to the earth's surface through kimberlite pipes, which are carrot shaped and widest at the surface. Although not all kimberlite pipes are sources for diamonds, most diamonds are found in areas where kimberlite pipes occur.
Explain how erosion and isostasy eventually produce stable relatively thin continental crust?
As material is removed from mountains by erosion, the range floats upward to regain its isostatic balance. This process can be thought of as "the pull of erosion." As the mountains wear down to a low plain, erosion becomes virtually ineffective and the now this crust achieves isostatic balance; the former mountain belt becomes part of the craton.
When was John Craton born?
John Craton was born in 1953.
The relatively stable interior portion of a continent is known as a?
The relatively stable interior portion of a continent is a craton.
Why is only a portion of the North American craton is visible?
Platforms and shields together make up cratons. The shield is the part of the craton that is exposed at Earth's surface and the platform is the part of the craton that is covered by sedimentary strata.
What is the stable core of a continent?
The stable core of a continent is the old, interior portion that has not experienced significant tectonic activity such as mountain-building or rifting for a long time. It consists of ancient, stable landmasses with low seismic activity and often includes cratons - the oldest and most rigid parts of a continent's lithosphere.

What is the birth name of Sexy Suz?

What is the birth name of Ricky Acker?
Ricky Acker's birth name is Richard Craton Acker.
What is an aulacogen?
An aulacogen is a tectonic trough on a craton which is formed as the failed arm of a triple-rift junction.
The relatively stable interior portion of a continent?
The crust beneath a continent, also known as the continental shield, is a relatively stable region in the interior of a continent. This region is characterized by old and stable geological features like cratons and shields, which have not experienced significant tectonic activity for millions of years.
