Some of the various reasons given for exploring and excavating these polar areas, is to discover the pathways of deep-sea water currents, excavate ice cores to discover secrets about earth's prehistory, track polar bears and penguins to discover their seasonal habits, monitor krill populations, investigate the aurora borealis to see if it can be used as an alternative energy resource, and test artificial environments for their use as possible space survival stations. This book also has a lot of interesting information about glaciers: how they form, where they are usually located, how they effect the earth, and how they move over time. This is a great book for an elementary school student interested in glaciers, or any student (ages 8-12) interested in the various in-roads scientists have made in learning about these mysterious areas of our globe.
