| Which type of fossil fuel is used to generate most of the electricity in the United States? | Natural gas |
| Which type of fossil fuel is used to generate most of the electricity in the World? | Coal |
| Which type of fossil fuel provides for most of the World's energy needs? | Oil |
| A controversial method of drilling for natural gas that involves injecting toxic chemicals thousands of feet underground at high pressures to break up shale rock and release methane gas. | fracking |
| Which country would the Keystone XL pipeline have connected to oil refineries in the United States? | Canada |
| Which fossil fuel is the least polluting in terms of the amount of CO2 produced when it is burned to supply a certain amount of energy? | Natural Gas |
| TRUE or FALSE: Natural gas does not produce greenhouse gases when it is burned. | False |
| When the price of something, like gasoline, goes down, people use ____ of it. | more |
| Which type of fossil fuel needs to be refined in order to separate out useful products (like gasoline) that are mixed in with it? | oil |
| Crude oil is a mixture of many different types of hydrocarbons, like octane, and butane, and heavier lubricating oils. Crude oil needs to go through the oil refining process so that these things can be separated from each other based on a process called distillation which is based on the fact that different sized hydrocarbons have different ____ points. | boiling |
| Fossil fuels are made of a class of chemicals called hydrocarbons which only have two elements in them, _____ and _____. | hydrogen and carbon |
| Fossil fuels are made of a class of chemicals called _______ which only have two elements in them, hydrogen and carbon. | hydrocarbons |
| Crude oil is a mixture of many different types of hydrocarbons, like octane, and butane, and heavier lubricating oils. Crude oil needs to go through the oil refining process so that these things can be separated from each other based on a process called ______ which is based on the fact that different sized hydrocarbons have different boiling points. | distillation |
| If the demand for a product increases, the price of that product usually ____. | increases |
| When the demand for a product (like oil) decreases because people decide to use less of it, it's price will usually ____. | decrease |
| When the price of a product decreases, the demand for that product usually ____. | increases |
| Something that can be found underground, can be burned for energy, and was created over millions of years from the decomposition and compression of once living organisms is called a(n) ____ fuel. | fossil |
| What are the three basic categories of fossil fuels? | Coal, oil, and natural gas |
| When you burn any type of fossil fuel, the two waste products are ___ and ____. | carbon dioxide and water |
| The biggest problem with using fossil fuels for energy is that it increases the amount of ___ in the atmosphere which causes ____. | carbon dioxide, global warming |
| The process of removing carbon dioxide from the air or from the chimneys from a power plant that uses fossil fuels, and then pumping it deep underground in hopes that it will stay there is called _____. | carbon sequestration |
| True or False: It is possible to make a coal-fired power plant that doesn't add greenhouse gases to the atmosphere. | TRUE (But the process of capturing the carbon dioxide and pumping it deep underground (ie - carbon sequestration) makes it too expensive compared to other energy sources, like natural gas, or even alternative energy sources like wind and solar, that it isn't really used and probably never will be to any significant extent) |
| Which type of fossil fuel puts the most carbon dioxide into the air when it is burned to produce a certain amount of energy? | Coal |
| Which hydrocarbon is a much more powerful greenhouse gas than carbon dioxide? | methane (also known as natural gas) |
| Natural gas is mostly made of _____. | methane |
| Another term that is used to describe methane is _____. | natural gas |
| Which type of fossil fuel are plastics made from? | oil |
| True or False: It is a good idea to burn plastic waste so that it doesn't take up space in landfills. | False (It is a horrible idea to burn plastic. Doing so puts a wide variety of toxic cancer causing chemicals in the air including dioxins and PCBs) |
| The burning of which type of fossil fuel puts a toxic element called mercury into the air which can cause significant problems with the development of your nervous system, including your brain, even in low concentrations. | Coal |
| The burning coal puts a toxic element called _____ into the air which can cause significant problems with the development of your nervous system, including your brain, even in low concentrations. | mercury |
| The burning coal puts a toxic element called mercury into the air which can cause significant problems with the development of your _____ system, even in low concentrations. | nervous |
| A controversial drilling method called fracking is used mostly to get a type of fossil fuel called ____. | natural gas |
| Two big concerns with the drilling method called fracking are that the toxic fluids used in the process may end up polluting _______ and also lead to the escape of ____ into the atmosphere which is a strong greenhouse gas. | ground-water, methane |
| Most electric power plants in the world require a fuel that generates enough heat so that water ____ and expands to cause a _____ to turn an electric generator. | boils, turbine |
