6th grade science: renewable and nonrenewable resources
understanding our natural resources is key to protecting the environment. we divide these resources into two groups. renewable resources are those that can be replaced in a short time or are always available. examples include solar energy from the sun, wind energy, and hydropower from moving water. in contrast, nonrenewable resources exist in limited amounts and take millions of years to form. the most common nonrenewable resources are fossil fuels - which include coal, oil, and natural gas. while fossil fuels provide a lot of energy, using them can cause pollution. because we cannot make more nonrenewable resources quickly, conservation (using less) and stewardship (taking care) of our resources are essential.

question
answer each question by circling the best answer.
which of the following resources are classified as nonrenewable fossil fuels? (select all that apply.)

□ wind
□ coal
□ solar
□ oil
□ hydropower (water)

a power plant that burns coal is using a resource that takes millions of years to form. this means coal is a -

a. hydroelectric resource
b. nonrenewable resource
c. renewable resource
d. geothermal resource

why are renewable energy sources considered more sustainable for long - term use than nonrenewable sources?

a. they produce more pollution than nonrenewable sources.
b. they are much less expensive to set up in the short term.
c. they come from resources that are limited and will eventually run out.
d. they come from resources that will not run out or can be replaced quickly.

reasoning
explain why you chose your answer

Explanation:

• For the first question: According to the text, non - renewable fossil fuels include coal and oil. Wind, solar, and hydropower are renewable resources.
• For the second question: The text states that non - renewable resources take millions of years to form. Since coal takes millions of years to form, it is a non - renewable resource. Hydroelectric (related to hydropower - renewable), renewable (opposite of what we need as coal is non - renewable), and geothermal (not relevant to the description of coal's formation time) are incorrect.
• For the third question: The text defines renewable resources as those that can be replaced in a short time or are always available. Option D aligns with this definition. Option A is wrong as renewable resources generally produce less pollution. Option B is not the reason for sustainability (cost is not the key factor for long - term sustainability as per the text). Option C describes non - renewable resources.

Answer:

• First question: Coal, Oil.
• Second question: B. nonrenewable resource.
• Third question: D. They come from resources that will not run out or can be replaced quickly.
