Cracks in rocks widen as water in them freezes and thaws. How does this affect the surface of the Earth?
It reduces the rates of soil formation.
It changes the chemical composition of the rocks.
It exposes rocks to increased rates of erosion and weathering.
It limits the exposure of rocks to acid precipitation.
How can urbanization affect a local area?
It can increase the number of invasive species in an area.
It can decrease the risk of water pollution in an area.
It can increase the risk of flooding in an area.
It can decrease the need for natural resources in an area.
Which is a farming technique that could improve the soil and the environment?
using fueled machines that will turn the soil continuously
creating undisturbed layers of mulch in the soil
placing inorganic chemical fertilizers in the soil
irrigating the soil with salty water
Subsurface ocean currents continually circulate from the warm waters near the equator to the colder waters in other parts of the world. What is the main cause of these currents?
differences in the topography along the ocean floor
differences in density of ocean water
the rotation of Earth on its axis
movement of the jet stream
What is most responsible for the presence of groundwater in an area?
the movement of water from a confined aquifer into surface water
the movement of surface water and precipitation through soil and rock
the movement of water from streams and rivers to watersheds
the movement of surface water through impermeable rock
Which is the most common contamination source for freshwater resources?
runoff
digging wells
melting of glaciers
lightning
A community decides to upgrade its water purification and management systems. What lasting impact could this have on available freshwater?
It could cause a decrease in water demand.
It could cause a decrease in the water levels.
It could cause an increase in waterborne diseases
It could cause an increase in the freshwater supply.
Which storm most likely develops as air masses interact with the warm water in the northwest Pacific Ocean?
typhoon
tornado
blizzard
monsoon
Which is associated with an increase of chlorofluorocarbons in the environment?
an increase in health risks associated with UV radiation
an increase in levels of methane gas in the atmosphere
an increase in ozone levels in the upper atmosphere
an increase in acid precipitation
Which natural phenomenon occurs as a result of Earth rotating on its axis?
movement of tectonic plates
deep ocean currents
seasonal changes
day and night
Urban City X has been referred to as an urban heat island because it tends to be warmer than the surrounding rural areas. The report below lists changes that have occurred in one year in Urban City X.
Report for Urban City X:
Eight roads were repaved.
The population increased by 20%.
Public transportation increased by 5%.
Four new apartment complexes were built.
Plans were drafted to build a local park.
A meeting was held about alternative energy sources.
What is the main cause of Urban City X being an urban heat island?
the planting of trees and other vegetation
the building of rooftop gardens
the installation of solar panels
the construction of parking areas and road systems
What long-term impact could the destruction of large areas of forests have on Earth?
decreased rates of erosion
increased atmospheric carbon dioxide levels
decreased amounts of acid rain
increased atmospheric oxygen levels
Why is it important to conserve the biodiversity of Earth?
to decrease the amount of global predator populations
to decrease the stability of major global ocean currents
to increase the stability of ecosystems during environmental changes
to increase the amount of nonrenewable resources located in the lithosphere
How does the tilt of the Earth’s axis affect the seasons?
by changing the amount of direct solar energy reaching the surface of Earth
by influencing the rate of chemical reactions occurring in the atmosphere
by deflecting the harmful rays of radiation emitted by the sun
by changing the speed of the rotation of Earth
How could the introduction of a nonnative species of plant affect an ecosystem in North Carolina?
It could pollinate the native plant species, producing a disease-resistant species.
It could reduce the competition for space and light with native plant species.
It could take over the habitats of the native plant species.
It could cause some insect species to destroy native plant species.
Which change would best aid a farmer in making the transition from conventional farming techniques to more sustainable farming techniques?
reduce the ratio of essential elements in the fertilizer
irrigate crops using well water
rotate the types of crops grown
plant only genetically modified crops
Which would most likely cause a reduction in the amount of coal and natural gas on Earth?
a continual increase in the amount of pollution in Earth’s atmosphere
a continual increase in the number of people on Earth
a continual decrease in the amount of water in Earth’s aquifers
a continual decrease in the amount of rain forests on Earth
Which is an effect of lower levels of solar radiation striking Earth?
increased incidences of skin cancer
decreased rates of photosynthesis
increased phytoplankton activity
decreased carbon dioxide levels
Which will most likely form when movement along a plate boundary forces a landmass to be pulled apart?
volcanic island arc
continental mountains
continental rift
oceanic trench
