What is global warming?
the melting of ice caps and glaciers
the increasing heat of Earth's asthenosphere
the increasing temperature of Earth's atmosphere
the decrease of oxygen level in the Earth's atmosphere
What is greenhouse effect?
warm atmosphere around Earth caused by trapped sun's radiation
absorbs and emits radiant energy from the sun
increased carbon in the Earth's atmosphere
increasing Earth's temperature
How urbanization affect an area?
decreases human population
increase the risk of flooding in an area
decreases the need of natural resources
Which strategy reduces the amount of carbon dioxide generated by power plants?
removing sulfur from coal
stop generating electricity
capture carbon dioxide emission
reduce the amount of natural gas in generating energy
How agriculture can negatively impact the environment?
It releases CO2 into the atmosphere.
It can increase the amount of flooding.
Farmers use fertilizers which contaminate rivers and streams.
Agriculture reduces the amount of oxygen in the atmosphere.
What natural resource is commonly obtained by surface mining?
Why hydrofracking is performed?
to prevent ground water contamination
to prevent air pollution in the area of the well
to increase the flow of natural gas from the well
to reduce the amount of contaminant in the natural gas
What is the major advantage that alternate energy has over fossil fuels?
Alternate energy is more efficient than fossil fuels.
Alternate energy does not produce radioactive waste.
Alternate energy increases the amount of sulfur dioxide ejected into the atmosphere.
Alternate energy reduces the amount of carbon dioxide ejected into the atmosphere.
Which of the following types of alternate energy is commonly located near the coast of North Carolina?
Which risk is associated with oil drilling?
It extracts radioactive elements which are health risks for workers.
It removes land from beneath the surface which can cause sinkhole.
It can lead to an oil spill in the middle of the ocean.
It removes soil which increases oil erosion.
Which is a major disadvantage of wood harvesting and deforestation?
It can lead to soil erosion and surface disruption.
It releases harmful pollution into the soil.
It discharges sulfur dioxide into the atmosphere
It increases health risks for workers.
Today why are fossil fuels more commonly utilized than alternate energy?
Resources for alternate energy methods are non-renewable
Alternate energy methods are more harmful to the environment
Alternate energy methods have a specific disadvantage which make them less efficient
Alternate energy methods are extremely dangerous and present health risks to workers
Why should the farming industry adopt sustainable agriculture practices?
To reduce the environmental degradation
To increase the use of irrigation systems
To increase the number of non-point sources of pollution
