This photo shows several different types of minerals. What tests could you perform to help tell them apart? Choose two answers.

• put the rocks in water to see if they float.

• scratch the rocks with a known mineral to test the hardness.

• drop them to see if they bounce.

• break the rocks to see if they form flat or rough surfaces.

• The resource is inconvenient to use.

• The resource is more expensive than a renewable resource.

• The resource cannot be easily replaced after it is used up.

• The resource exists only as a solid, not a liquid or gas.

Coal, oil, and natural gas all formed from natural processes that continue today. Why are they identified as nonrenewable resources if nature can replace them? 

•  because we are using them faster than nature can replace them

• because they can't ever be replaced

• because nature can only replace them during certain times of the year

• because they can only be used once
