Wikify date November 2010 File Tens.tif right Diagram of Geologic Tension In geology , the term tension refers to a stress mechanics stress which stretches rocks in two opposite directions. The rocks become longer in a lateral direction and thinner in a vertical direction. One important result of tensile stress is jointing in rocks. However, tensile stress is rare because most subsurface stress is compressive, due to the weight of the overburden. Jointing Tensile stress forms joints in rocks. A joint geology joint is a fracture that forms within a rock, whose movement to open the fracture is greater than the lateral movement that takes place. Joints are formed in the direction perpendicular to the least principal stress, meaning that they are formed perpendicular to the tensile stress. ref Chrowder, Thomas and Rollin D. Salisbury Chamberlin. Geology Geologic Processes and their results. 2nd ed. New York Henry Holt and Company, 1909. Print. ref One way in particular that joints can be formed is due to fluid pressure, as well as at the crest of folds in rocks. This occurs at the peak of the fold or due to the pressure Fluid pressure fluid pressure because a localized tensile stress forms, eventually leading to jointing. ref Secor, Donald. Role of Fluid Pressure in Jointing . Columbia, South Carolina University of South Carolina, Columbia, 1965. eBook. ref Another way in which joints form is due to the change in the weight of the overburden .

The geology of the Netherlands describes the geologic timescale geological sequence of the Netherlands . Large parts of the Netherlands today are below sea level and have in the past been covered by the sea or flooded at regular intervals. The modern Netherlands formed as a result of the interplay of the four main rivers Rhine , Meuse , Schelde and IJssel and the influence of the North Sea . The Netherlands is mostly composed of river delta deltaic , coast al and Aeolian processes eolian derived sediments during the Pleistocene glacial and interglacial periods. Fairly all of the west Netherlands is composed of the Rhine Meuse river estuary , but civilisation human intervention greatly modified the natural processes at work. Most of the western Netherlands is below sea level due to the human process of turning standing bodies of water into usable land, a polder . In eastern Holland, remains are found of the last ice age , which took place approximately ten thousand years ago. As the continental ice sheet moved in from the north, it pushed moraine forward. The ice sheet halted as it covered the eastern half of the Netherlands. After the ice age ended, the moraine remained in the form ...
