Look at a world map— locate the following and mark them on a world outline map; Urals, Alps, Iceland, San Andreas fault, Andes mountains, volcanoes in Italy. Use a plate tectonics map (page 199 in the Scott Foresman
Earth Science
text) to explain why these formations are found where they are.

On a world map locate the placement of some of the recent geological events; earthquakes or volcanoes. Use the plate tectonics map to explain what has happened and why.

Look at the continental drift maps in Appendix II. Using the maps given follow the changes that occurred along the eastern edge of Pangaea beginning in the Triassic. What happens to the Tethys Sea as it becomes the Mediterranean? What can you predict might happen there in the future?

Ancient coral reefs are porous and can trap and hold petroleum. Look at the Devonian map to find some promising areas to drill for oil. Look at a map of the present continents to determine whether you are drilling on land or offshore. Place your findings on a world outline map.

Look at the Cambrian map to determine which continents probably had a warm climate. Where would you expect to find coral limestone deposits and why? On a world outline map locate the present position of those places. Which of those areas might have coral reefs growing there now?

Remembering that species begin to differ when separated and appear most alike when able to spread freely over a range; and that barriers to ocean life include land masses, deep ocean water, and cold temperatures; how did the corals change over geologic time? Look especially at the Devonian, the Permian, the Cretaceous, and the present.
