Inspire Science Unit 2, Natural Resources in the Environment and Impact of Energy Use
renewable resource
Any natural resource (as wood or solar energy) that can be replenished naturally
fossil fuels
Coal, oil, natural gas, and other fuels that are ancient remains of plants and animals.
How are fossil fuels formed?
Heat and pressure turn animal and plant remains into fuels.
natural resources
Materials or substances such as minerals, forests, water, and fertile land that occur in nature
......... is pumped out of the ground and can be used for cooking and heating our homes.
Natural gas
nuclear engineering
The study of the use of nuclear power
Our world uses up a large number of nonrenewable sources of energy. What should we do about energy sources in the future?
We will need to find ways to use renewable sources of energy.
biofuel
a fuel made directly from living matter
nonrenewable resource
a resource that cannot be replaced
environmental scientist
a scientist who studies the effects of human activities on Earth's land, air, water, and living things and also tries to solve problems relating to the use of resources
Reducing the amount of resources we use, called ____________, will allow resources to be saved for a later time.
conservation
hydroelectricity
electricity produced by flowing water
solar power
energy from the sun that is converted into thermal or electrical energy
nonrenewable resources examples
fossil fuel (coal, oil and natural gas) diamonds, metals
Electricity produced from flowing water is called

Fossil fuels are
non-renewable resources
Burning oil as fuel can release harmful substances called ______________.
pollution
The overuse of fossil fuels leads to _____.
pollution
When an item is _______ , it is made into a new product
recycled
A device that produces electricity from sunlight is a

Non-renewable resources are resources that
take so long to form that they cannot be replaced quickly
conservation
the act of saving, protecting, or using resources wisely
geothermal energy
the energy produced by heat within the earth
recycle
the process of making new products from materials that were used in another product
wind energy
Energy derived from wind by means of windmills or wind turbines.
reuse
to use again
reduce
to use less of something
alternative energy sources examples
wind, solar, biofuel, geothermal, hydropower

wood
Fossil fuels used in transportation can cause problems. Which is a possible solution to these problems?
Use renewable energy sources in cars, such as biofuels and solar power.
alternative energy sources
a source of energy other than the burning of a fossil fuel
pollution
any harmful substance that affects Earth's land, air, or water
Which method is used to change plant and animal materials into useable fuel?
biomass conversion
Which is not a source of renewable energy?
fossil fuels
Which type of energy would best be used in an area with a lot of hot springs?
