Which of the following best describes how coal is formed?
A.
Tiny aquatic plants and animals die and sink to the ocean floor, where they are covered in mud and
silt. In an anaerobic reaction over time, pressure compresses out the liquid and leaves behind car-
bon to form short carbon chains.
B.
The remains of plants from crops are pressed to remove the liquid and are then heated at high tem-
peratures until coal is formed.
C.
Vegetation dies and is covered in mud in an anaerobic environment. Over time, the pressure com-
presses out the liquid, leaving the carbon matter behind to form complex chains of carbon com-
pounds.
D.
Tiny aquatic plants and animals die and sink to the ocean floor, where they are covered in mud and
silt. In an anaerobic reaction over time, pressure compresses out the liquid and leaves behind car-
bon to form long carbon chains.
E.
Charcoal forms when wood is heated to high temperatures, causing thermal decomposition. A mix-
ture of gases and water vapors escape, leaving the solid residue called charcoal.

All the following are consequences of global climate change EXCEPT:
A.
Melting of glaciers and polar ice caps
B.
Rising sea levels
C.
Alteration of worldwide precipitation patterns
D.
Little or no impact on the human food supply
E.
Increased global temperatures
