Moderately elevated tablelands are thus the characteristic feature of the continent, though the surface of these is broken by higher peaks and ridges.
(So prevalent are these isolated peaks and ridges that a special term [Inselberglandschaft] has been adopted in Germany to describe this kind of country, which is thought to be in great part the result of wind action.) As a general rule, the higher tablelands lie to the east and south, while a progressive diminution in altitude towards the west and north is observable.
It is formed by a widening out of the eastern axis of high ground, which becomes subdivided into a number of zones running north and south and consisting in turn of ranges, tablelands and depressions.

While the limestone has been mainly worn down to a lowland, it forms fine scarps and tablelands in county Sligo and other western regions.
