Natural Resources
What is a natural resource?
Something found naturally that humans can use.
What is a nonrenewable resource?
A natural resource that can not be replenished or takes significantly longer to replenish than the rate it is being used.
Why is petroleum considered to be a nonrenewable resource?
A. It constantly forms within Earth.
B. It is difficult to obtain and transport.
C. It releases harmful chemicals when burned.
D. It requires a very long period of time to form.
D. It requires a very long period of time to form.
What is a geological change?
A change to Earth's geology (surface)
True or false: water is a natural resource.
True
What is a renewable resource?
A natural resource that does not run out.
What are the advantages of using resources such as geothermal energy, solar energy, and wind energy? A. They can generate power by burning wastes.
B. They increase the amount of greenhouse gases.
C. They come from energy sources that never run out.
D. They produce large amounts of energy from burning fuels.
C. They come from energy sources that never run out.
How does the geological change or erosion distribute resources?
Erosion is the movement of material, it can move resources
True or false: all natural resources are renewable.
False
What is a fossil fuel?
A nonrenewable natural resource made of biomatter/organic matter (fossils)
Why is nuclear energy considered a nonrenewable resource?
A. Nuclear radiation does not run out.
B. It comes from radiation from the sun.
C. Uranium ore is replaced on a geologic timescale.
D. Uranium replenishes more quickly than it is being used.
C. Uranium ore is replaced on a geologic timescale.
Volcanic activity can lead to uneven distribution of resources, on what type of plate boundary are you most likely to find volcanoes?
Convergent plate boundaries
True or false: Natural resources are evenly distributed across the Earth
False
Why is it important for humans to use renewable resources instead of relying on nonrenewable resources?
Eventually nonrenewable resources can run out, using nonrenewable resources can have more of a negative impact on the environment.
Which energy resource comes from plant material or other organic matter?
Fossil fuels
How can tectonic plate movement impact the distribution of minerals and soil?
Plates move across the Earth
As they move, plates can destroy land forms and erode minerals and soil.
Give 3 examples of a natural resource
water, wind, solar, geothermal, minerals, trees, fossil fuels
What is a potentially renewable resource?
A resource that is limited but replenishes fairly rapidly (hours, years, decades, not thousands or millions of years)
Which statement describes a resource that could be both renewable and nonrenewable?
A. Petroleum is drilled from rock on the ocean floor.
B. Solar energy is used to produce both heat and electricity.
C. Turbines are constructed to use wind to make electricity.
D. Trees are cut down to make wood products faster than new trees can grow.
D. Trees are cut down to make wood products faster than new trees can grow.
How can human action erode soil and contribute to its uneven distribution?
Mechanical movement, breaking down the quality of the soil (pesticides, fertilizers, other chemicals)
