They are most commonly found in the upper part of the river where there are marked changes of geology in the rivers valley. In the upper Teesdale an outcrop of igneous rock called the whin sill caused the formation of the High Force Waterfall which is 22cm high and is the tallest waterfall in England. The waterfall is formed by The bed of the river

These sites made her very interested in pursuing a career in Geology and Archaeology. When she met Louis she had already become an expert at illustrating the finds at archaeological digs at the age of twenty. They had three sons: Jonathan in 1940‚ Richard in 1944‚ and Philip in 1948.

"Our ultimate purpose is to forecast earthquakes on land because earthquakes cause so much damage and kill so many people‚" says Jian Lin‚ Ph.D.‚ senior scientist in the Department of Geology & Geophysics at Woods Hole Oceanographic Institution. By understanding what happens below the Earth’s surface‚ geophysicists are hoping to be able to send a warning to those above-ground. The researchers say it is easier to study fault lines below

an interest in natural history where he was influenced by the work and evolutionary theory of French naturalist Jean-Baptiste Lamarck (1744-1829). In 1831 Darwin joined a five year exploration ship‚ The Beagle‚ where he read the ‘Principles of Geology’ (1830)‚ the works of geologist Charles Lyell (1797-1875). Lyell comments on the change in rock sediments and suggests that fossils found in rocks may be proof that animals lived thousands‚ if not millions of year previously. This influenced the ideas
