• Laws are educated guess, while theories are yet to be tested

• Laws are always true and theories are sometime true

The Glyptodon is a giant, armadillo-like animal that once lived on Earth and weighed over 2000 kg and live exclusively in warm, coastal regions. In many ways it resembled the 4 kg armadillo that lives today. From the information given, what is the probable reason the Glyptodon is not alive today?

• Predators hunted the animal for food to the point of extinction

• The animal could not adapt to environmental changes

• The animal ate too much food

• The Glyptodon had genetic variation

Fossil Fuels such as natural gas and petroleum (oil) contain carbon. How did the carbon get into the fossil fuels?

• It migrated into them from the rocks in which the fossil fuels are found

• It seeped out of coal buried near fossil fuel deposits underground

• It was in the air that was trapped underground when the fossil fuels formed
