Question

Which answer choice is the best example of a non-renewable natural resource?

Answer

The answer is "Oil is made by the Earth over millions of years through the pressurization of organic material under Earth's crust." This process occurs over millions of years, and is naturally occuring.

Compare your answer with the correct one above

Question

Which answer choice is NOT a natural resource?

Answer

Gasoline is not a natural resource because it is man-made.

Compare your answer with the correct one above

Question

Certain types of metals, like gold, are both naturally occurring and can be created in a lab. (This process is not used often because it is expensive and not efficient!) This tells us what about metals like gold?

Answer

The answer is "Gold is a natural resource that can sometimes be synthetic." Some substances can be either natural or synthetic and it depends on how the substance was made.

Question

Plastics are made from natural materials such as cellulose, coal, natural gas, salt and crude oil through something called a polymerisation process. This tells us that plastics are:

Answer

The answer is "synthetic materials." All synthetic materials are made from natural resources, but do not exist in the world unless they are man-made.

Compare your answer with the correct one above

Question

True or False: The good news about synthetic materials, like plastic, is that we can always make more, no matter how much we need.

Answer

The answer is "False. Even though we can make more synthetic materials like plastic, they are made from natural resources which sometimes take a long time for the Earth to make more of."
