Question 3

How does energy relate to the way that streams meander?

Accepted Answer

At a stream's headwaters,a stream's energy is focused on downcutting.Downstream the focus changes to a sinuous side-to-side motion.This reflects how the stream minimizes its resistance to flow and dissipates its energy along the course.Meanders are the form a stream takes as it adjusts its energy so that it can carry away all the sediment that it produces.
