(a) The most characteristic feature of the epeirogenic movement is that there is no crumpling of the rock-beds. The beds remain nearly horizontal.

(b) These earth movements affect areas of wide areal distribution.

(c) The periods of epeirogenic movements are quite large.

(d) These movements are reversible in nature. The same area may undergo upheaval followed by subsidence and vice versa.

(e) They affect the thickness of the sedimentary series, being formed, at the time of their operation.
