Geology is the investigation of the structures and highlights of land surfaces. The geology of a territory could allude to the surface structures and highlights themselves, or a portrayal (particularly their portrayal in maps).
Geology is a field of geoscience and planetary science and is worried about neighborhood detail all in all, including alleviation, yet additionally characteristic and fake highlights, and surprisingly nearby history and culture. This importance is more uncommon in the United States, where geological guides with rise shapes have made geography inseparable from help.
Geography from a thin perspective includes the account of help or landscape, the three-dimensional nature of the surface, and the distinguishing proof of explicit landforms. This is otherwise called geomorphometry. In current use, this includes age of rise information in computerized structure (DEM). It is frequently considered to incorporate the realistic portrayal of the landform on a guide by an assortment of methods, including shape lines, hypsometric colors, and alleviation shading.

The term geography started in old Greece and proceeded in old Rome, as the point by point depiction of a spot. The word comes from the Greek τόπος (topos, “place”) and – γραφία (- graphia, “writing”). In traditional writing this alludes to expounding on a spot or places, what is currently to a great extent called ‘neighborhood history’. In Britain and in Europe by and large, the word geology is still now and again utilized in its unique sense.
Point by point military overviews in Britain (starting in the late eighteenth century) were called Ordnance Surveys, and this term was utilized into the twentieth century as conventional for geographical studies and maps. The soonest logical reviews in France were known as the Cassini maps after the family who created them more than four generations. The expression “geological studies” gives off an impression of being American in cause. The most punctual point by point overviews in the United States were made by the “Geographical Bureau of the Army,” shaped during the War of 1812, which turned into the Corps of Topographical Engineers in 1838. After crafted by public planning was expected by the U.S. Land Survey in 1878, the term geographical stayed as an overall term for definite reviews and planning programs, and has been received by most different countries as standard.
In the twentieth century, the term geography began to be utilized to depict surface portrayal in different fields where planning from a more extensive perspective is utilized, especially in clinical fields like nervous system science.
