What is the difference between tors, inselbergs, bornhardts and koppies?

Question

No Wiki answers, I read it and I still don't understand the difference between them. I don't need a very detailed answer, just tell me a bit of their distinctive characteristics and what differentiates them from each other.

Thanks!

Answer 1

the spelling

Answer 2

The word Tor means tower and it was used by people in England since ancient times describe isolated blocky hills of rock about the same size as a house. Fine examples are found on the tops of granite hills in Devon and Cornwall.

An inselberg was first described in 1900 by Dr. W. Bornhardt, who described them as large hills, big rocky outcrops, that suddenly rise out of the flat savanna plane like islands in a sea.

A bornhardt is a variety of inselberg that has a dome or smoothly convex outline. Ularu (Ayers Rock) is a bornhardt.

Koppies (castle koppies) are a variety of inselberg that consists of many vertical towers and stout pinnacles of rock. The Peter Weir film, Picnic at Hanging Rock, was filmed at Hanging Rock, Victoria, a fine example of a koppies.

Answer 3

A tor is the same as a roche mountonne or a glacially formed outcrop of bedrock.

Inselbergs and bornhardts are the same thing, an outcrop of bedrock surrounded by alluvial, but not formed by a glacier.

Koppie is just a little hilltop, not necessarily formed by a glacier or composed of bedrock.
