BESC COMPREHENSIVE STUDY GUIDE
TESTED QUESTIONS AND VERIFIED
ANSWERS
●● Sinkholes result from ________.
Answer: overconsumption of water from aquifers weakening the
substrate
●● Methods for desalinating sea water to produce fresh water include
________.
Answer: reverse osmosis and distillation
●● Which of the following best describes a floodplain?
Answer: a region of land that is periodically flooded when a river
overflows
●● The formation of sinkholes has become a fairly common
phenomenon in the state of Florida. Most sinkholes are small, but some
sinkholes have led to catastrophic property damage and loss of life. One
September day in 1999, folks began to notice that Lake Jackson in the
panhandle region was shrinking. Within a few days, it was almost gone.
A sinkhole had opened beneath the lake and drained it, along with all of
the fish and alligators. Another sinkhole formed just 10 miles from Walt
,Disney World® in August 2013, swallowing a 48-unit villa at Summer
Bay Resort®.
As aquifers lose water, their substrates can become weaker and less
capable of supporting overlying strata and any human structures built
upon them. In such cases, the land surface above may subside.
Sometimes subsidence can occur locally and suddenly, in the form of
sinkholes, areas where the ground gives way with little warning. Once
the ground subsides, soil
Answer: the surrounding soils are compacted and the size of the aquifer
is reduced
●● Recent research that analyzed the content of commercial bottled
water indicates that ________.
Answer: bottled water is no safer or purer than most samples of tap
water
●● Artificial wetlands ________.
Answer: can help purify water and also provide wildlife habitat

Answer: a drought had recently occurred, along with increased
development and groundwater use
●● A long, raised mound of earth used to control flooding along a river.
Answer: levee
●● Xeriscaping can save water by ________.
Answer: planting native or drought-resistant plants which require less
water than typical landscaping plants
●● ...
The main environmental problem caused by harvesting bottom-dwelling
mollusks is ________.
Answer: habitat destruction
