When the combustion engine was invented it had many positive effects on society, but years later it has been discovered that the burning of oil and coal has one major negative effect on the environment. What is that negative effect?
It improves air quality.
It uses renewable resources.
It causes a hole in the ozone.
It increases the greenhouse effect.
New technology, such as renewable energy sources, has many positive aspects such as
using nonrenewable resources.
reducing the emissions of carbon dioxide.
increasing the annual average temperature.
increasing the cost of energy sources such as fuel.
Oil, natural gas, and coal are considered to be nonrenewable resources. Why are these fuels considered to be nonrenewable?
The burning of these fuels does not allow the waste products to be recycled.
These fuels are available in a limited supply--when the fuel is used it is no longer available.
The amount of pollution released from the use of these fuels is much higher than with renewable sources.
The technology used to generate energy by the use of these fuels is much older and less efficient than current technology.
According to the information in the graph, the BEST way for Virginia to cut water consumption would be to decrease
coal mining.
automobile use.
drinking supplies.
electricity usage.

Burning fossil fuels increases the amount of carbon dioxide in the atmosphere. What is the LIKELY negative effect on Earth if extra carbon dioxide is added to our atmosphere?
acid rain
global warming
increased plant growth
a hole in the ozone layer
Over the last several decades, scientists have addressed the problem of nonrenewable natural resources such as fossil fuels. Humans are using fossil fuels at a rapid rate and scientists believe that one day we will run out of them. To solve this problem, research has been conducted on alternative energy sources. One alternative energy source is nuclear energy. Although nuclear energy is a good solution to this problem, there are concerns.
All BUT ONE of these describe a concern about nuclear energy.
presence of radioactive waste
little if any carbon emissions released into the air
contamination risk when transporting radioactive materials
thermal pollution from water released into nearby environment
Above is a bar graph showing how the average family uses water. Fresh water is a vitally important resource, and its supply is limited. Because of this limited supply, it is important for us to try and conserve water as much as possible.
Which drain on your water supply could you eliminate to help reduce water usage in your home?
the "other" category
the "leaks" category
the "shower" category
the "clothes washer" category
Many cultures and religions have customs which deal with the way they use the land. For example, in Judaism, it is required that a field be left fallow (unplanted) every seventh year. What is one beneficial effect of customs like this?
They prevent the land from being overused.
They cause less competition among farmers.
They make the land more valuable to farmers.
They force people to farm more recklessly at other times.
Which is the BEST way to conserve the Earth’s forests?
Ride a bike to work.
Set up a compost pile.
Recycle paper products.
Turn down your thermostat.
Water conservation. What do the words bring to mind? Doing without? In reality it can be done by making very minor changes around the home. Evaluate the bar graph showing how a typical family uses water at home. Select the practices described below that could practically help to conserve water use at home.
Don't flush the toilet very often. Do not bathe unless you are very dirty.
Stop using the dishwasher to wash dishes. Only take a bath on the weekends.
Don’t leave your tap running while brushing your teeth, shaving, or washing the dishes. Fix leaky faucets and pipes right away.
Use environmentally friendly products whenever you can. When you must use environmentally hazardous products, be sure that you dispose of them properly.
Earth's atmosphere is made up of mostly nitrogen (78%) and oxygen (21%); however, there are other gases in smaller amounts, like argon, carbon dioxide, neon, helium, hydrogen, and more. If there was an increase of carbon dioxide in the atmosphere, how would this affect temperature?
The temperature would increase globally.
The temperature would decrease globally.
Temperature doesn't relate to the composition of the atmosphere; it has to do with the sun's rays.
The temperature would not be affected since carbon dioxide is only one component in the atmosphere.
After a solar power plant is constructed, which statement best describes the waste produced and its environmental impact?
Solar energy produces no waste and has almost no impact on the environment.
Solar energy produces large waste and has considerable impact on the environment.
Solar energy produces no waste and but has considerable negative impact on the environment.
Solar energy produces small amounts of waste and has a small negative impact on the environment.
These graphs show global temperatures (left) and carbon emissions (right) over time. The graph of global temperatures is based on 1951-1980 average temperatures, which was 14 degrees Celsius (57.2 degrees Fahrenheit). The data show how high or low Earth's surface temperature was above that average (14 degrees Celsius). The Global Fossils Carbon Emissions graph shows annual carbon dioxide emissions based on fuel type. Human activities such as fossil fuel combustion, cement production, and agriculture all contribute to carbon emissions. Based on the data shown, what reasonable conclusion can be drawn?
Global temperatures tend to increase as carbon emissions increase.
Global temperatures increase over time, regardless of human activity.
Natural gas emissions have no effect on global temperature increases.
The burning of coal has had the greatest effect on global temperatures.
