Question

What made the Ozark Mountains?

Answer 1

The Ozarks were formed in a different way. They are the result not primarily of folding and faulting but of erosion. The rocks that formed the Ozarks were originally sand, silt, and the remains of marine animals laid down in a shallow sea at the beginning of the Paleozoic Era, which began 542 million years ago.
