Escarpment
An escarpment is a steep slope or long cliff that forms as a result of faulting or erosion and separates two relatively level areas having different elevations. The terms ''scarp'' and ''scarp face'' are often used interchangeably with ''escarpment''. Some sources differentiate the two terms, with ''escarpment'' referring to the margin between two landforms, and ''scarp'' referring to a cliff or a steep slope. In this usage an escarpment is a ridge which has a gentle slope on one side and a steep scarp on the other side. More loosely, the term ''scarp'' also describes a zone between a coastal lowland and a continental plateau which shows a marked, abrupt change in elevation caused by coastal erosion at the base of the plateau. Formation and description Scarps are generally formed by one of two processes: either by differential erosion of sedimentary rocks, or by movement of the Earth's crust at a geologic fault. The first process is the more common type: the escarpment is a t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Treaty Of Aranjuez (1779)
The Treaty of Aranjuez (1779) was signed on 12 April 1779 by France and Spain. Under its terms, Spain agreed to support France in its war with Britain, in return for assistance in recovering their former possessions of Menorca, Gibraltar and Spanish Florida. While Spain refused to become formally involved in the American Revolutionary War, they allowed goods to be shipped through Louisiana, avoiding the British blockade while their recapture of Florida denied the Royal Navy bases on the Gulf Coast. Outside North America, they regained Menorca but failed to take Gibraltar, despite a huge investment of men and money. With the exception of Menorca and Florida, the 1783 treaties between Britain, France and Spain largely returned the position to that prevailing before the war. Background Under the 1713 Treaty of Utrecht, Spain ceded Menorca and Gibraltar to Britain and regaining them became a primary objective. During the Seven Years' War in 1756, Spain was allied with France; they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
