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 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
the 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

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. 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 changin 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 or 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 affect of lower levels of solar radiation striking Earth?
increased incidences of skin cancer
decreased rates of photopsynthesis
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
Which will most likely occur before a volcanic eruption?
an increase in acid rain production
an increase in earthquake activity
an increase in lava flow
an increase in mud flow
A rural, forested area receives a lot of rain in a short amount of time What would most likely cause potential flooding in the area?
if the area has a large uncharged aquifer beneath it
if the water level in the area is below the zone of saturation
if the ground of the area is already saturated with water
if the ground of the area is mostly sandy soil
Which is the best way to conserve worldwide freshwater resources?
build more roads and highways for cars and trucks
increase the amount of land used to raise cattle
develop more modern coal-powered plants
use more efficient irrigation techniques
Which statement best describes the ozone layer of Earth?
It helps reduce the amount of ultraviolet radiation reaching the surface of Earth.
It prevents the formation of severe storms in the stratosphere of Earth
It increases the amount of nitrogen in the troposphere of earth
It forms a magnetic field in the mesosphere of Earth
Which is a biotic factor that could affect an ecosystem?
dust storms moving through an ecosystem
bacteria harming the health of organisms in an ecosystem
large amounts of acid rain precipitation seeping into the soul in an ecosystem
high levels of carbon dioxide entering the atmosphere within an ecosystem
How do weathering and erosion affect Earth's surface?
Both force tectonic plates to move across the ocean floor
Both cause sedimentary rocks to form igneous rocks
Both cause mountain ranges to become taller
Both break down rocks and create new soil
How can oil and natural gas be extracted from the Earth?
by digging in areas of volcanoes
