Question

why do all altitudinal landforms get eroded at the bottom side?​

Answer 1

Answer:

Upper course river features include steep-sided V-shaped valleys, interlocking spurs, rapids, waterfalls and gorges. Middle course river features include wider, shallower valleys, meanders, and oxbow lakes. Lower course river features include wide flat-bottomed valleys, floodplains and deltas.

Most valleys on dry land are formed by running water of streams and rivers .The bottom of a valley is called its floor. Most floors slope downstream. Mountain valleys usually have narrow floors. The part of the floor along riverbanks is called flood plain. A valley's sides are called valley walls or valley slopes.
