Federal Street Press: New York.}} If the inselberg is dome-shaped and formed from [granite](/source/granite) or [gneiss](/source/gneiss), it can also be called a ''[bornhardt](/source/bornhardt)'', though not all bornhardts are inselbergs. An inselberg results when a body of rock resistant to [erosion](/source/erosion), such as granite, occurring within a body of softer rocks, is exposed by [differential erosion](/source/Denudation) and lowering of the surrounding landscape. == Etymology == [[File:Pietra di bismantova castelnovo monti.jpg|thumb|right|[Pietra di Bismantova](/source/Pietra_di_Bismantova) in the [Apennines](/source/Apennines), [Italy](/source/Italy)]] === Inselberg === The word ''inselberg'' is a [loan word](/source/loan_word) from [German](/source/German_language), and means "island mountain". The term was coined in 1900 by geologist [Wilhelm Bornhardt](/source/Wilhelm_Bornhardt) (1864–1946) to describe the abundance of such features found in eastern [Africa](/source/Africa).{{cite book |last1=Holmes |first1=Arthur |title=Holmes Principles of Physical Geology |date=1978 |publisher=Nelson |isbn=978-0-17-771299-9 }}{{page needed|date=December 2021}} At that time, the term applied only to arid landscape features. However, it has since been used to describe a broader geography and range of rock features, leading to confusion about the precise definition of the term. In a 1973 study examining the use of the term, one researcher found that the term had been used for features in [savannah](/source/savannah) climates 40% of the time, arid or semi-arid climates 32% of the time, humid-subtropical and arctic 12% of the time, and 6% each in humid-tropical and Mediterranean climates. === Monadnock === [[File:Mount Monadnock.JPG|thumb|[Mount Monadnock](/source/Mount_Monadnock) in [New Hampshire](/source/New_Hampshire), USA.]] ''Monadnock'' is derived from an [Abenaki](/source/Abenaki_language) term for an isolated [hill](/source/hill) or a lone mountain that stands above the surrounding area, typically by surviving erosion. Geologists took the name from [Mount Monadnock](/source/Mount_Monadnock) in southwestern [New Hampshire](/source/New_Hampshire).[Raymo, Chet](/source/Raymo%2C_Chet) and [Raymo, Maureen E.](/source/Raymo%2C_Maureen_E.)
