NATIONAL GEOGRAPHIC Geoguide A Close Look at the Galapagos * Examine the map on page 10. What is the latitude of the GalA pagos? How is their location reflected in the name of the country that owns the islands? * To understand how the GalA pagos "poke" through the ocean in the image on pages 10-11, you can make a model of the island group. Cover the bottom of a baking dish with Play-Doh, then pinch up areas to simulate volca noes. Slowly flood the pan with water tinted blue with food col oring until just the peaks remain above water, as islands. * As tourism brings visitors and development-to the GalA pagos, the threat to the environ ment grows. What can be done to satisfy the needs of visitors and local people and protect the environment at the same time? * Introduced species-guava trees, pigs, and goats-have severely affected native plant and animal populations in the Gali pagos. Have any introduced spe cies, such as starlings or kudzu, caused problems where you live? Sleek divers that feed on fish, blue-footed boobies touch bills during courtship rituals.
