Question

difference between in inselburg and yardang in points

Answer 1

Yardangs are formed on vertical hard/soft layers of rock, while zeugen (this is its plural form) are formed on horizontal bands of hard/soft rocks giving it a more mushroom-like shape. The Great Sphinx of Giza has been sculpted in a yardang.

Answer 2

inselburg :
*An inselburg (island castle) is a castle surrounded by water.
*I think you mean inselberg (island mountain), also called monadnock
*It is is a large isolated hill rising abruptly from a flat or gently sloping plain
*It can occur in any type of climate — dry or wet, windy or still — unlike yardangs, which are sculpted by desert winds.
yardang :
* yardang, like a hoodoo, pinnacle, or spire, is a rocky outcropping in a desert
*Unlike inselbergs, yardangs can and frequently do occur in groups, can be rather small, and tend to have bizarre wind
*-sculpted shapes like towers or steeples or fins
