Question 3 0.4 pts The term grade refers to a stream's longitudinal profile that is concave upward -- steepest in the headwaters with a lower slope as the stream reaches the ocean. Rivers rarely reach this graded condition, because there are that form and break up the longitudinal profile. Select the best answer O that fills in the blank. O knickpoints aquifers lakes O base level

Answer 1

Rivers rarely reach knickpoints because there are that form and break up the longitudinal profile.

A waterfall or lake are examples of knickpoints, which are areas of a river or channel where the slope abruptly changes. Knickpoints, which are frequently the result of past erosion brought on by glaciers or differences in lithology, indicate various conditions and activities occurring on the river.

Knickpoints progress one cycle upstream or inland in the cycle of erosion model, replacing a previous cycle. A headcut is a knickpoint that is located at the head (most upstream extent) of a waterway. Other planetary planets with liquid-covered surfaces also feature knickpoint.
