1. Which of the following determines whether a
resource is a renewable resource or a
nonrenewable resource? A the cost for obtaining
and using the resource B the effects of the
resource on the environment C whether the
resource is used to generate energy or is made
into products D the rate at which the resource
can be replaced

formed around the intrusion. B First, the bottom
rock layer formed. The, the intrusion formed.
Finally, the other rock layers formed. C The
rock layers were folded, and then an intrusion

20. Fossils of coniferous leaves and wood that
date to the Early Eocene Epoch have been found in
Antarctica. The trees are similar to species
found today in southern Argentina and in Chile.
What does the presence of these fossils suggest
about the past environment of Antarctica?
