Briefly describe the formation of a natural levee
A. The maximum load of solid particles a stream can transport
B. Sand, gravel, and large boulders that are too large to be carried in
suspension, and instead move along the bottom of a stream channel
C. Soluble sediments that are carried in solution
D. A complex network of converging and diverging channels that thread
their way among numerous islands or gravel bars
E. The physical breakdown (disintegration) and chemical alteration
(decomposition) of rock at or near Earth’s surface
F. The process by which solid particles of various sizes are separated
and deposited in different location
A. Impermeable layers that prevent water movement
B. Permeable rock strata that permits water to flow
C. Localized zone of saturation above an impermeable layer
D. Where the water table intersects the Earth’s surface
E. Fountains of hot ground water ejected with great force
F. Ground water confined to a layer, in which the recharges area is
higher than the outlet
Question 8. Why is wind erosion more effective in deserts than in more humid
regions?
Question 9. Briefly describe the formation of a natural levee.
Question 10. Why are flash floods common in arid climates?
Question 11. Briefly describe at least six depositional features created by
glaciers.
Question 12. When examining the geology of a region for potential useable
aquifers, what characteristics, or factors would you consider? Discuss at
least three environmental concerns related to groundwater.
Question 13. Many developing countries with large river systems are rushing to
build dams for hydroelectric power to stimulate economic development. For
example, China completed the Three Gorges Dam, one of the world’s largest, on
the Yangtze River in 2006 and more recently Ethiopia has announced plans to
build the Grand Millennium Dam on the Nile River. There’s no question that
dams are of economic benefit but on the flip side, they may also have
unintended and undesirable costs. If you were in charge of planning the
construction of a large dam, what are some of the environmental and cultural
costs (other than monetary – please don’t discuss economic costs of dams as
your primary content) that you would consider undesirable and what would you
do to minimize these costs?
