Geomorphology, the science of understanding the shape of the Earthís surface, can be subdivided into categories such as glaciation, river systems, coastal processes and slope development. All are influenced by rock type and structure and the climate acting on them. Our library contains pictures to illustrate these phenomena.

Wastwater, Cumbria, U.K. A famous scree slope developed on the side of a glacial trough. The scree slope is composed of rock fragments of varying sizes which have been weathered from the slope, often by frost action, and carried down by gravity and water.

Skaftafellsjokul, Iceland. The decaying snout of a valley glacier descending from the Vatnajokul ice cap. This is second in size, in the Northern Hemisphere, to the Greenland ice cap. The glacierís snout is deeply crevassed and broken.† Meltwater laden with sediment flows in braided river systems southwards across the outwash plain to the North Atlantic.

Tresco, Scilly Isles, U.K. Many geomorphological features can best be appreciated from the air. These granite islands show features of rising sea-level and coastal deposition. The characteristic landscape of Tresco is seen, with small bulb fields separated by high wind-breaking hedges. The granite from which these islands are made is part of the batholith which is exposed on the English mainland in Cornwall and Devon.
