3- Which of the following is a key part of the formation of most natural arches?
A- jointing and other fracturing
B- folding of soft rock layers
C-volcanic eruptions
D-spheroidal weathering
E- none of the above
4-Which of the following descriptions best describes the landscape
shown in this photograph from the Investigation?
A-The balanced rock formed during a volcanic eruption.
B-This scene could have been formed by erosion of a layer of
sandstone.
C-The sparse vegetation and apparently dry conditions imply that
chemical weathering is relatively rapid here.
D-There are no joints visible in the photograph, nor would any be
expected in this type of rock.
5-Which of the following processes is most important in sculpting
the landscape shown in this photograph from the
Investigation?
A-movement driven by gravity
B-stream erosion
C-stream transport
D-wind erosion
6-The agent of transport that produces talus is
A-running water.
B-wind.
C-gravity.
D-glacier.
3- Which of the following is a key part of the formation of most natural arches?...
Section A 1) 2) 3) B. The accumulation of angular pieces of rock at the base of a slope is known as: A. parent material B. talus c. soil D. laterite E. caliche The down slope movement of material along a curved surface of rupture is a(n): A. rock fall B. slump C. mudflow Dearth flow E. rock slide The most widespread and costly of all mass wasting processes is: A. slump creep C. mudflows D. rock falls E. quick...
