A large flood in a river may cause abrupt shifts leading to the carving of a new channel. The point at which this change occurs is a(n)
A) type of dynamic equilibrium condition.
B) type of metastable equilibrium.
C) threshold.
D) input.

Question

Quizplus · Accepted Answer

The point at which a flood causes an abrupt shift and carves a new channel is known as a threshold. This threshold represents a significant change in the equilibrium of the river's flow and can have significant impacts on the surrounding ecosystem. A and B are not applicable in this context, and D does not accurately describe the threshold phenomenon.
