conservation the wise and careful use of energy resources is called ____ fossil fuels petroleum, natural gas, and coal are the three kinds of _____ coal the type of fossil fuel that forms only from the remains of plants is ____ nuclear wastes unwanted radioactive products formed during nuclear reactions are called ___ photovoltaic cells devices that use semiconductors to produce electricity from solar energy are _____ hydroelectricity electricity produces by falling water is called _____ tidal energy water that flows due to the gravitational forces among Earth, the Moon, and the Sun has energy referred to as ___ boron or cadmium rods the chain reaction in a nuclear reactor is controlled by inserting the _____ 35% the efficiency of most power plants is approximately _____ matter is converted into energy what is common to both nuclear fusion and nuclear fission coal which of the following is an example of a nonrenewable source of energy coal the most abundant fossil fuel is ___ biomass renewable organic matter, such as wood and rice hulls, are examples of _____ maintaining very high temps what is a major problem with developing a fusion reactor fractional distillation petroleum is separated into gasoline, lubricating oils, and other products through a process called ___ control rods to control the reaction in a nuclear fission reactor, the neutrons are slowed by ___ core the part of a nuclear reactor in which fuel is located is called the ____ uranium-235 nuclei in a nuclear reactor, electricity is produced from ____ equipment corrosion a disadvantage of using tidal energy is ____ the supply of fossil fuels is diminishing one reason alternative energy sources are needed is because ______ how do the masses of the atoms produces as a result of a fusion reaction differ from the masses of the atoms that result from a nuclear fission reaction? the masses of atoms produces as a result of fusion come together to make oen atom and as a result of fission the atoms split apart to make many atoms what kind of energy is given off from a nuclear fusion reaction and from a nuclear fission reaction? the kind of energy a nuclear fusion reaction makes is heat energy and the kind of energy a nuclear fission reaction is radioactive energy how do the waste products of nuclear fusion differ from the waste products of nuclear fission? the nuclear fission waste products are radioactive and nuclear fusion's waste is nonradioactive what is petroleums state of matter and what is it formed from? liquid, plants and animals what is coals state of matter and what is it formed from? solid, plants what is natural gasses state of matter and what is it formed from? gas, plants and animals make a concept map that classifies: coal, wind, water, uranium, petroleum, biomass, solar energy, an natural gas as a renewable source of energy or a nonrenewable source of energy ... give the advantages and disadvantages of using nuclear fission to generate electricity two advantages are it is quicker and it makes more energy than coal. Two disadvantages are that is is bad for the environment if the atoms escape and it produces radioactive waste what are some advantages and disadvantages of using wind as a source for generating electricity? some advantages are that is doesn't pollute and it is renewable. Some disadvantages are that they disrupt the migration course of birds, it ruins the landscape around the windmills, and they coast a lot to build why is it necessary to fine energy alternatives to fossil fuels? its necessary because they are big pollutants and eventually they will run out explain how fractional distillation is used to separate petroleum into components. fractional distillation if found in oil towers. the crude oil goes into the tower and the chemical compounds are boiled. eventually the ones with the lowest boiling point turn to vapor and rise to the top
