Gasoline
The table provides information on three alternative fuels.
(See attached diagram)
The data in this table can be used as evidence to support the claim that all of these fuels–
are very costly to produce.
exist in the same state of matter.
are made of natural materials.
take several days to produce.
Plastics are created from processed petroleum which is pulled up from below the ground. This is important because–
petroleum is a non-renewable resource.
processing and using petroleum releases contaminants into the environment.
plastic products are not biodegradable and pollute the environment.
all of the above.
Turpentine (C10H16) is produced through the distillation of tree resin. Humans could reduce the impact of turpentine production on forests by doing all of the following EXCEPT -
improving the distillation process to increase the amount of turpentine produced from tree resin.
finding a source, other than trees, that can be distilled to produce turpentine.
besides using the resin for turpentine, using the other parts of the tree for other purposes.
cultivating trees on land set aside specifically forproducing trees for turpentine.
Which of the following best describes a synthetic material?
Petroleum is refined through a chemical process to produce plastic that is carved into a figure
A tree is cut down, carved into a shape, then burned to add color
Sand is struck by lightning causing it to turn into glass that is then carved into a figure
Volcanic glass (obsidian) is carved and polished into a sculpture
