| Question | Answer |
|---|---|
| The remains of ancient organisms that changed into coal, oil, or natural gas. | Fossil Fuels |
| Most of the energy we use comes from a group of natural resources called? | fossil fuels |
| Oil deposits that can be extracted profitably at current prices using current technology. | Oil reserves |
| Why do YOU think oil production is increasing much more slowly than it has in the past? | maybe it's because of limits on refining capacity and inventory. |
| What are four main purposes for using fuel? | transportation, manufacturing, heating and cooling buildings, generating electricity to run machines and appliances. |
| Why would it not be beneficial to use coal to power and airplane? | would require hundreds of tons of coal |
| What are some disadvantages of electricity? | difficult to store and other energy sources have to be used to generate it |
| A machine that converts mechanical energy, or motion, into electrical energy | electric generator |
| Generators produce electrical energy by moving an electrically conductive material within a ? | magnetic field |
| This is a wheel that changes the force of a moving gas or liquid into energy that can do work. | turbine |
| How does a coal-fired power plant work? | 1. burn fossil fuels (heat) to boil water and produce steam 2. steam powers the blades of a turbine (spin) 3. turbine is connected to an electric generator, generating electricity 4. steam from the turbine is directed to a condenser where it cools and |
| What requires energy? | literally EVERYTHING |
| How do fossil fuel deposits form; coal? oil? natural gas? | coal forms from the remains of plants that lived in swamps hundreds of millions of years ago; oil and natural gas result from the decay of tiny marine organisms that accumulated on the bottom of the ocean millions of years ago |
| The quality of coal varies; higher-grade coals, such as bituminous coal, produce more ___ and less ___ than lower-grade coal, such as lignite. | more heat and less pollution |
| Found in all grades of coal; can be a major source of pollution when coal is burned. | sulfur |
| When high-sulfur, low-grade coal is burned, it releases much ____ ____ than lower-sulfur bituminous coal does. | more pollution |
| Result from burning high-sulfur coal without adequate pollution controls? These are serious problems in countries such as __. | air pollution and acid precipitation; China |
| Oil that is pumped from the ground is also known as | crude oil (petroleum) |
| Anything made from crude oil, such as fuels, chemicals, and plastics is called ? | petroleum product |
| Where are most of the world's oil reserves located? | Middle East |
| How much petroleum accounts for the world's commercial energy use? | 45% |
| Environmental effects of using oil? | they release pollutants (internal combustion engines (smog and health problems) and oil spills |
| In developing countries, cars are generally older, and the gasoline that they burn contains significantly more ____. | sulfur |
| About 20% of the world's nonrenewable energy comes from ? | natural gas |
| Because burning natural gas produces ___ ___ than other fossil fuels, vehicles that run on natural gas require fewer pollution controls. | fewer pollutants |
| Today, fossil fuels supply about ___ percent of the energy used in developed countries. | 90 |
| As the demand for energy resources increases, the cost of fossil fuels will likely __ __ to make other energy sources more attractive. | increase enough |
| Oil deposits that can be extracted profitably at current prices using current technology. | oil reserves |
| 5 factors that influence the value of a fuel | energy content, cost, availability, safety, and byproducts of the fuel's use |
| Analyzing Relationships: What is the relationship between natural gas and petroleum? | Petroleum products are fuels made from crude oil and hydrocarbons contained in natural gas. Petroleum products can also be made from coal, natural gas, and biomass. |
