Multiple-Choice Quiz

Our Multiple-Choice Quiz will test your knowledge of the basic concepts and ideas offered in Chapter 16. By successfully reviewing these concepts, you will reinforce your comprehension of these geographic ideas.

This activity contains 20 questions.

	Streams generally erode _____.   along the inner banks of a meander along the outer banks of a meander along both banks in a stretch of straight water along the stream bottom none of the above

	Which of the following is not a component of the stream load?   dissolved load alluvial load bedload suspended load

	What would prevent a delta from forming where a large river enters the ocean?   active ocean currents along the coast calm ocean conditions the river is carrying a heavy load of alluvium sluggish ocean currents along the coast a shallow coastal shelf

	Overland flow is increased by   joints in bedrock. high-intensity precipitation. heavy forest cover. permeable substrate. none of the above.

	The amount of solid material a stream has the potential to transport is called   capacity. stream load. competence. discharge. saltation.

	Which of the following drainage patterns is the most common throughout the world?   annular trellis dendritic rectangular radial

	Silt is normally transported in river flows   as bankload. by saltation. as suspended load. by traction. as dissolved load.

	Natural levees form when   alluvium is deposited when water spills over the banks of a channel during flood flow. a river is meandering over resistant rock. alluvium is deposited on the bottom of a stream channel during normal flow. alluvium is deposited below the lip of an interfluve. none of the above.

	Channelization of a river or stream results in all of the following, except   an improvement of commercial navigation on large rivers. the lowering of the water table in the channelized stream reach. reduction of the magnitude and frequency of flooding downstream of the channelized reach. an increase in the channel gradient in the channelized stream reach.

	A penneplain is the _____ of the classical geomorphic cycle of erosion.   youthful stage mature stage beginning old-age stage end product

	A braided river channel   usually has a relatively narrow and deep cross section. usually has a steeper longitudinal gradient than a meandering stream. usually is the most common type of natural channel in the world. usually is found only in arid climate regions. usually is dominated by suspended load sediment types.

	Knickpoints are best associated with   oxbow lakes. meandering streams. waterfalls and rapids. yazoo streams. backswamps.

	Which one of the following best describes the general pattern of erosion by streams?   episodes or pulses of erosion associated with periods of environmental change episodes or pulses of erosion associated with periods of environmental stability slow, constant, and gradual erosion lateral cutting by streams; streams do not downcut none of the above

	This photograph shows part of the Himalaya foothills. Here, local relief is less dramatic than in the uplands and stream gradients are more gentle. You might expect streams in this area [Source]   to carry greater amounts of bedload than in the headwater region. to aggrade as coarser materials drop out of suspension. to erode and form entrenched meanders. te develop back swamps and yazoo tributaries.

	Under constant discharge, an increase in the width or depth of a stream channel will ____ the velocity of water flow.   increase decrease

	A ____ stream runs during and just after a rain.   perennial ephemeral intermittent

	A ____ stream pattern forms on the sides of large volcanoes.   dendritic centripetal radial trellis

	The boundary of a watershed is defined by   the largest order of the main stream. a continental divide. a drainage divide. the number of tributaries in a basin. none of the above.

	The suspended load of a stream consists of particles that   move by saltation. move by traction. are held aloft in the flow of water. are dissolved in water. are none of the above.

	_____ is the total load a stream is capable of transporting.   Bedload Capacity Competence Suspended load none of the above.
