Questions and Answers

Match the following stream types with their descriptions:

Type A = Youthful streams that are actively down-cutting their channels and tend to be relatively straight Type B = Streams with a step-pool morphology consisting of a series of pools connected by rapids and waterfalls Type C = Streams that typically flow into wide and relatively low-gradient U-shaped glaciated valleys Type D = Streams with a braided pattern, characterized by a series of narrow channels separated by gravel bars

Match the following stream types with their descriptions (cont.):

Type E = Streams occupying a wide, flat flood plain with a low gradient and developing a sinuous flow pattern Type F = Streams similar to Type E but with a higher sinuosity and a more exaggerated meandering pattern Type G = Well-developed meandering rivers Type A = Streams that are relatively straight and ungraded

Match the following terms with their definitions in a stream:

Glide = A smooth, uninterrupted flow of water over a shallow area of the stream Riffle = A shallow, fast-moving and turbulent section of the stream characterized by rough water and small waves

Match the following statements with the fate of the American Chestnut:

Once considered the finest chestnut tree in the world and played a vital role in the ecosystem = American Chestnut Reduced to 1-10% of its original size due to the chestnut blight, a disease = American Chestnut A large, fast-growing deciduous tree native to North America, particularly the Appalachian Mountain range = American Chestnut Signup and view all the answers

Match the following stream features with their descriptions:

Pool = Deeper water and slower current Glide = Section transitioning from deeper to shallower Riffle = Shallow, faster-moving section Paleoindian culture = Time period of 1300-7500 BC Signup and view all the answers

Match the following stream features with their effects:

Glide = Transitioning from deeper to shallower Riffle = Removing fine sediments and oxygenating the stream Pool = Forming on the outside bends of meanders between riffles Macroinvertebrates = Sensitive to pollution Signup and view all the answers

Match the following stream features with their impacts on water quality:

Study Notes

Stream Characteristics

A pool in a stream is characterized by deep, slow-moving water with little turbulence.
A glide in a stream is characterized by smooth, fast-moving water with little turbulence.

Stream Types

Type F streams are characterized by a series of narrow channels separated by gravel bars.

American Chestnut

The American Chestnut population drastically reduced due to a factor that caused its decline.
The decline of the American Chestnut population also affected the Paleoindian culture in western Maryland.

Macroinvertebrates

According to Maryland DNR, certain macroinvertebrates are most sensitive to pollution.

Stream Features

Various stream features have different effects on water quality.
