Answers

1
What is most responsible for the presence of groundwater in an area?
movement of surface water and precipitation through soil
movement of water from streams and rivers to watersheds
movement of surface water through impermeable rock
movement of water from a confined aquifer into surface water
2
Cracks in rocks widen as water in them freezes and thaws. What does this affect?
limits the exposure of rocks to acid precipitation
changes the chemical composition of the rocks
exposes rocks to increased rates of
reduces the rates of soil formation
3
Which will most likely occur before a volcanic eruption?
an increase in lava flow
an increase in earthquake activity
an increase in mud flow
an increase in acid rain production
4
Which is the most common contamination source for freshwater resources?
lightning
runoff
melting of glaciers
digging wells
5
Which will form when movement along a plate boundary forces a landmass to be pulled apart?
continental rift
continental mountains
volcanic island arc
oceanic trench
6
Which is associated with an increase of chlorofluorocarbons in the environment?
increase in levels of methane gas in the atmosphere
increase in acid precipitation
increase in health risks associated with UV radiation
increase in ozone levels in the upper atmosphere
7
How does the tilt of the Earth's axis affect the seasons?
by changing the amount of direct solar energy reaching Earth
by deflecting harmful rays of radiation emitted by the sun
by changing the speed of rotation of the Earth
by influencing the rate of chemical reactions in atmosphere
8
A forested area receives much rain in a short amount of time. What could cause flooding?
if the area has a large aquifer beneath it
if the ground is already saturated with water
if the water level is below the zone of saturation
if the ground is mostly sandy soil
9
Which is an effect of lower levels of solar radiation striking Earth?
increased phytoplankton activity
decreased carbon dioxide levels
increased incidences of skin cancer
decreased rates of photosynthesis
10
Which statement best describes the ozone layer of Earth?
increases the amount of nitrogen in the troposphere
prevents the formation of severe storms in the stratosphere
reduces the amount of UV radiation reaching Earth's surface
forms a magnetic field in the mesosphere
11
Which natural phenomenon occurs as a result of Earth rotating on its axis?
deep ocean currents
movement of plate tectonics
seasonal changes
day and night
12
Which is a farming technique that could improve the soil and the environment?
irrigating the soil with salty water
using fueled machines that will turn the soil continuously
placing inorganic chemical fertilizers in the soil
creating undisturbed layers of mulch in the soil
13
How does introducing a nonnative species of plant affect an ecosystem in NC?
take over the habitats of the native plant species
pollinates native plants, producing disease-resistant plants

14
What is the main cause of subsurface ocean currents?
differences in density of ocean water
differences in topography along the ocean floor
the rotation of Earth on its axis
movement of the jet stream
15
What impact could upgrading water purification systems have on available freshwaer?
cause an increase in the freshwater supply
cause an increase in waterborne diseases
cause a decrease in water levels
cause a decrease in water demand
16
Which change shows a transition from a conventional farming technique to a sustainable one?
rotate the types of crops grown
irrigate crops using well water
