waves of translation

The disintegration or dissolving of surface and subsurface rock is called _________

weathering

notched cliff

Mass movements are classified based on _________.

speed and moisture content

Which process is most associated with chemical weathering?

spheroidal weathering

Where do deposition and erosion of material occur along a meander?

all of the above

Which of the following features indicates that a stream has undergone uplift and rejuvenation?

alluvial terraces

What portion of a stream's sediment load is held aloft in the water and transported downstream?

suspended load

Hydration is a process whereby a mineral

swells on the absorption of water, creating stress in rock

What is suspended load?

the fine-grained particles that travel in the water column above the stream bed

Limestone must contain a minimum calcium carbonate content of ______ for karst topography to form.

80%

Which of the following rivers is characterized by internal drainage?

Humboldt

Which of the following statements about loess is correct?

Loess deposits in the United States and Europe are derived from glacial outwash deposits.

How are oxbow lakes formed

Oxbow lakes form when one meander erodes into another, cutting off water to part of the stream channel.

The dynamic equilibrium model of landforms refers to

a balancing act between tectonic uplift and reduction by weathering and erosion in a given landscape

What is a meander scar?

a landscape feature formed after an oxbow lake dries up

What is an oxbow lake?

a meander that has been cut off from the original stream channel

An urban hydrograph shows ____ a rural hydrograph does.

a more rapid response to precipitation and higher peak flow than

What is a stream terrace?

a remnant of an older floodplain that sits above the stream valley

What stream process erodes the streambed by grinding it with sediment and rock fragments?

abrasion

What are the three types of loads carried by streams?

bed, suspended, dissolved

Water that is more than 35 percent salinity is called ______________.

brine

Which of the following weathering processes is most likely to produce karst topography?

carbonation

Complete this analogy: Bouncing is to sand as suspension is to

clay
