In the south-west there is a fairly extensive lowland in south Devonshire watered by the Exe in its lower course.
Thus interpreted, the Appalachian forms of to-day may be ascribed to three cycles of erosion: a nearly complete Mesozoic cycle, in which most of the previously folded and faulted mountain masses were reduced in Cretaceous time to a peneplain or lowland of small relief, surmounted, however, in the north-east and in the south-west by monadnocks of the most resistant rocks, standing singly or in groups; an incomplete Tertiary cycle, initiated by the moderate Tertiary upwarping of the Mesozoic peneplain, and of sufficient length to develop mature valleys in the more resistant rocks of the crystalline belt or in the horizontal strata of the plateau, and to develop late mature or old valleys in the weaker rocks of the stratified belt, where the harder strata were left standing up in ridges; and a brief post-Tertiary cycle, initiated by an uplift of moderate amount and in progress long enough only to erode narrow and relatively immature valleys.
More than a hundred almost reach the sea, from which they are separated by detrital lowland or terminal moraines.
It falls into three distinct parts: (1) the largest portion, with the city of Bremen, lying on both banks, but chiefly on the right, of the lower course of the Weser, surrounded by the Prussian province of Hanover and the grandduchy of Oldenburg, and consisting in the main of lowland country intersected by canals and dykes; (2) the town and district of Vegesack, lying separate from, but immediately north of the main portion, on the right bank of the river; (3) the port of Bremerhaven, 46 m.
