In structural geology, an anticline is a type of fold that is an arch-like shape and has its oldest beds at its core. A typical anticline is convex up in which the hinge or crest is the location where the curvature is greatest, and the limbs are the sides of the fold that dip away from the hinge.
Best Answer: The age of continental rocks are older than that of sea floor rocks. Ocean crusts form and deplete rapidly, and are generally quite young (180 million years or so for the oldest).Continental crusts generally are older (billions of years) because they deplete slowly, and mainly through erosion.he oldest rocks on continental crusts are generally in the center of the continent, while the oldest rocks of ocean crust are generally farthest away from the ocean-ridges.
