Exam 15: River Systems and Landforms

John Wesley Powell put forward the idea of base level, which refers to

Stream transport involves all of the following except

Bed load is moved by

A graded stream is one that has achieved a dynamic equilibrium between degradation and aggradation.

This tree-like drainage pattern efficiently moves water and sediment through its system due to minimization of the total length of each branch.

The area of land from which all water in it drains into the same place is known as a(n)

A squeeze-and-release action works to loosen and lift rocks in a stream channel. This is an example of

Large river systems that have multiple large channels across a vast floodplain are termed

Define the following terms: drainage basis, drainage divide, interfluve, and valley.

This drainage pattern is characteristic of dipping or folded topography.

Erosion is a degrading process whereas deposition is an aggradating process.

Stream drainage patterns are determined by which of the following?

The ultimate base level is

Rectangular drainage patterns form primarily as a result of

The general term for channelized water flow, regardless of size, is

As the discharge of a stream increases, which of the following also happens?

A floodplain is composed of alluvium.

The primary cause of terrace formation is

Stream drainage always eventually reaches the ocean.

In most rivers in humid regions, discharge increases downstream.
