declined

high physical separation between homes, work, and shopping and
congested traffic due to inadequate road networks
prior to WWII people living in cities in the United states enjoyed: -
ANSWERS-widespread used of public transportation
in most large cities, suburban commuters might benefit from the use
of light rail systems for commuting. in most cities, if commuters
switched from driving to rail commuting, they would: - ANSWERS-
use fewer natural resources, especially fossil fuels
urban sprawl has resulted in: - ANSWERS-wildlife habitat
fragmentation
,the most important limiting factor for most driver-commuters is... -
ANSWERS-at the time it takes to drive to their job
____ is the reason why summers in coastal areas are less hot than
inland and winters are less cold - ANSWERS-water's heat capacity
which of the following is not an example of a green-house gas? -
ANSWERS-nitrogen gas
Many of us know of people who swear they can tell if it is going to
rain by the pain in their bodies, usually their knees. It turns out that
there is some truth to this. In people with joint pain, it is thought that
normal atmospheric pressure helps to compress the joints (and
therefore minimize the joint pain). But when atmospheric pressure
(outside the body) drops, their joints swell, and it feels like there is
increased pressure in their body (i.e., joint pressure, not atmospheric
pressure). So, if your grandpa says he feels like his joint pressure is
increasing, it is likely because atmospheric pressure is decreasing.
What happens next (weather-wise)? - ANSWERS-it's going to rain
The dense traffic and wide highways typical of cities like Riverside,
CA and Atlanta, GA are the result of - ANSWERS-federal income
taxes which are higher in urban areas.
Driving through slow, congested traffic on a busy Saturday afternoon,
you barely have time to notice all of the signs on the shopping malls.
Your friend wants you to head to the next town but it is unclear where
, one town begins and ends. Which of the factors just described are
characteristic of urban sprawl? - ANSWERS-abundant shopping
malls, unclear boundaries between towns, and dense, congested traffic
Risk in environmental health is most related - ANSWERS-hazards
multiplied by vulnerability
PETE (code 1) and HDPE (code 2) plastics - ANSWERS-can be
recycled and made into many useful products
what is not true about ozone? - ANSWERS-the ozone hole is an area
of low ozone concentration in the stratosphere over the north pole
(1) What is really old-fashioned about nuclear power? (2) What is
really cutting-edge and innovative about nuclear power? (3) What is
really scary about nuclear power? - ANSWERS-(1) it's just heating
water to rotate a turbine. (2) It can provide power for extremely long
periods of time. (3) There is a possibility of a meltdown that harms
humans and the environment.
what is the approximate half-life of U-235? - ANSWERS-700 million
years
the concentration of U-235 needed to generate nuclear power is
approximately (1) ___, but the concentration of U-235 needed to
generate nuclear weapons is approximately (2) _____. - ANSWERS-
(1) 4%, (2) 85%
