Exam 11: Running Water

Briefly explain the trade-offs that accompany any flood control project.

Lateral erosion forms conditions along a stream valley that promote movement of material by a geologic process known as ____________________.

Mass wasting can be an important source of sediment carried in a stream.

What are the different sources of water on the Earth?

The process by which water vapor reenters the atmosphere by evaporation from plants is called ____________________.

The lower limit to which the stream can erode is its ____________________.

A stream that cuts directly through ridges that lie in their paths are called ____________________.

What is a graded stream?

How is the discharge of a stream calculated?

A rill is the precursor to a brook, creek, stream, or river.

Why does the velocity of a stream generally increase downstream even though the gradient decreases?

What are some of the reasons why running water is important to humans?

What are braided streams, and where do they form?

How is the gradient of a stream calculated?

What powers the hydrologic cycle?

The outer bank of a meander in a meandering stream is called the ____________________, where (erosion/deposition) ____________________ takes place. The deposit on the opposite side (inner bank) of the channel is called the ____________________, which is where (erosion/deposition) ____________________ occurs.

What is the infiltration capacity of a surface? On what factors does the infiltration capacity of a surface depend?

A dry surface has a higher infiltration capacity than a moist surface.

Former meanders that have been cut off from the stream are called ____________________.

If a superposed stream erodes downward into resistant rock and cuts narrow canyons, the resulting feature is called a(n) ____________________.
