Alluvial fans - CORRECT ANSWER: fan-shaped deposits of coarse sediments at the

foot of a mountain range , where a stream enters a flat valley floor

Alpine-type mountain building (and 2 examples) - CORRECT ANSWER: The Himalaya

Mountains and the Appalachians. large mountain chains formed by compressional stresses associated with continental convergence.

Andean-type mountain building - CORRECT ANSWER: Subduction beneath a

continent, long lasting igneous activity, & volcanic mountain growth is triggered by partial melting in the mantle wedge and lower congenital crust. Ex: Andes Mountains

Anticlines - CORRECT ANSWER: are upfolded or arched rock layers.

aquifer - CORRECT ANSWER: a permeable body of rock or sediment that transmits

groundwater freely

aquitard - CORRECT ANSWER: a low-permeability layer that hinders or prevents

groundwater flow.

are cirque, arete, and horn produced by glacial erosion? - CORRECT ANSWER:

mountain formations caused by glacier erosion

are fjord produced by glacial erosion? - CORRECT ANSWER: deep steep sided inlets of the sea (cliff)

• / 3

are glacial striations produced by glacial erosion? - CORRECT ANSWER: areas carved out by glacial movement

are glacial troughs produced by glacial erosion? - CORRECT ANSWER: as a glacier

grows and moves they widen and deepen stream valleys

are hanging valleys produced by glacial erosion? - CORRECT ANSWER: - perched

areas (waterfalls) that are created when a main glacier moves through a smaller stream

asthenosphere - CORRECT ANSWER: is the weak, flowing layer beneath the

lithosphere and has a slower wave velocities.

Barrier islands: - CORRECT ANSWER: elongated ridges of sand that run parallel to the coast, but separated from the mainland by a lagoon

Basins - CORRECT ANSWER: are downwarped circular or oval structures.

Baymouth bar: - CORRECT ANSWER: a spit that extends across a bay and closes it off from the ocean

can any rock deform in a brittle or ductile manner? - CORRECT ANSWER: Any rock can deform in a brittle or ductile manner, depending on the conditions of the deformation.

Changes to regional stream drainage systems - CORRECT ANSWER: Glacial advance

or retreat changes the routes of rivers and modifies the sizes and shapes of many valleys

Confining pressure - CORRECT ANSWER: equal in all directions, associated with the weight of the overlaying rocks.

• / 3

contamination - CORRECT ANSWER: sewage, fertilizers, industrial chemicals and

materials, leaking landfills, household chemicals, hazardous or nuclear waste, and dissolved natural substances.

Cordilleran-type mountain building (and 1 example in North America) - CORRECT ANSWER: the collision of volcanic islands arcs or small slivers of continental crust with the edge of a continental crust with the edge of continent to form mountainous regions.The north American cordillera along the west coast of the continent.

Could more than one 100-year flood occur in a 1-5 year time span? - CORRECT

ANSWER: yes especially if tropical storms or hurricanes occur.

Crustal subsidence and rebound - CORRECT ANSWER: - massive ice sheets cause

downwarping of the continental crust

cut bank - CORRECT ANSWER: the outer curve of a meander bend is a zone of active erosion, so the channel tends to migrate in the direction of each cut bank.

Define hydraulic gradient - CORRECT ANSWER: the slope of the water table

Define mass wasting - CORRECT ANSWER: the downslope movement of loose rock

material under the influence of gravity.

Define the geothermal gradient - CORRECT ANSWER: the profile of Earth's

temperature at each depth

Deformation - CORRECT ANSWER: Refers to all changes in the size, shape, or

position of a rock body in response to stress.

Deltas - CORRECT ANSWER: form when sediment-rich streams enter a relatively still body of water
