Sediment sequences deposited under glacial conditions during the Pleistocene period cover some 10% of the earth's land surface. This program concentrates on the interpretation of a sediment sequence exposed in a river cliff cut by the River Severn in England. Techniques of sampling and analysis are illustrated, with emphasis on the measurement of particle size and of particle dip and orientation. This analysis suggests that the deposits were laid...

"This book provides an illustrated guide to the wide variety of features found on and around the world's glaciers and ice sheets as well as the products of glacial erosion and deposition. It stresses both the beauty and utility of glaciers and demonstrates how our lives are influenced by one of the key components of the Earth system, the cryosphere. The authors cover glaciers and their landforms and explain some of the key concepts in glaciology and...

How are glaciers formed? Where are they found? How and why do they move? How have they shaped the land? Using examples filmed in Iceland, the Alps and the UK and with the help of satellite images, graphics and interviews with some of the world's leading glaciologists, this program illustrates and explains the processes and landforms associated with glaciers. An excellent case study of the very latest research and current thinking on glaciation.

Different multi-media techniques demonstrate aspects of surface formation. Beginning with plate tectonics, numerous photos document the individual landscapes and their origin. Using selected typical landscapes, an animated model illustrates how the changes take place. Includes a built-in navigator, online help, glossary and more than 100 examples from all over the world.

Among the most striking and startling features of the Earth are its immense craters and hidden underground passageways. Created instantly by huge meteoric impacts or gradually by the erosion of solid rock, these features reveal the varied geologic processes that have shaped our Earth, forming its craters, caverns and canyons. Starting with the Earth's early history when the planet was bombarded by asteroids and comets, geologist Jon Erickson details...

"This book provides a new look at the climatic history of the last 2.6 million years during the ice age, a time of extreme climatic fluctuations that have not yet ended. This period also coincides with important phases of human development from Neanderthals to modern humans, both of whom existed side by side during the last cold stage of the ice age. The ice age has seen dramatic expansions of glaciers and ice sheets, although this has been interspersed...

Overview: An exploration into the cultural, natural, and historical significance of islands, this unique book delves into what islands represent, how different cultures view them, and even the geological roots of island formations. Islands play a significant role in both the ancient and modern world, and play an important part in how civilizations were formed. The book looks at islands through the lens of the philosophical, psychological, biological,...
