McGinty's Science CUA #3 Review

Wood can be used as a fuel for campfires or heating homes in the winter. What makes wood an advantage instead of using fossil fuels?

• Nature will always be able to supply more wood in the future.

• Wood is way easier to use.

• Waste is not produced by wood.

• A piece of wood holds more energy than the same amount of fossil fuel.

Matt seems to think that fossil fuels are classified as renewable resources because they form naturally.

Kinsey disagrees with Matt and argues that fossil fuels are nonrenewable and may not be available in the future.

Which statement best supports Kinsey's argument?

• The burning of fossil fuels releases many gases such as carbon dioxide.

• The environment can be damaged because of the mining of fossil fuels.

• It can take millions of years of natural processes to form fossil fuels.

• Fossil fuels have a lot of energy stored in them and are easy to use.

Mr. McGinty's Science Class wants to make great choices in the use of resources.

All of the following are wise choices to conserve natural resources, EXCEPT

• Recycle Gatorade bottles and Dr. Pepper cans.

• Turn laptops off when they are not in use.

• Bring your lunch in a lunchbox to school instead of putting it in a paper bag.

• Dispose of plastic bags in a trash can instead of a recycle bin.

What is the most important physical property of a sedimentary rock that makes it ideal for oil and natural gas to be developed and stored in them?

• Sedimentary rocks are extremely hard.

• Sedimentary rocks are porous due to empty spaces between the sediments.

• Sedimentary rocks have many different colorful layers.

• Sedimentary rocks are not porous.

Oil and water both can collect underground. What does underground supplies of oil and water have in common?

• They both form from rocks which rise up from Earth's interior.

• Both fill cracks or holes inside rocks or between cracks.

• Both are liquids that seeps down from the surface.

• Both flow in underground rivers or streams.

Which answer choice correctly identifies resources as Renewable or Nonrenewable?

• Renewable: Wind, Water

  Nonrenewable: Minerals, Oil

• Renewable: Water, Wood

  Nonrenewable: Coal, Solar

• Renewable: Coal, Natural Gas

  Nonrenewable: Water, Minerals

• Renewable: Wood, Water

  Nonrenewable: Wind, Oil
