					Topography
A Geography Lesson
  Standard/s: ……
What is topography?
   Topography, a term in geography, has come to
    refer to the "lay of the land", or the
    physiogeographic characteristics of land in terms
    of elevation, slope, and orientation. Terrain is a
    similar term, used more to describe the land itself
    than the study of it. "Relief" is often used to refer
    to the third dimension of a map whether in
    actuality (as in a "raised relief" map, or drawn, as
    with contours, hachures or shading) or the
    territory it describes.
Types of topography
   Plains and flat lands
   Mountains
   Plateaus
   Hills
   Low lands
Definitions
Plains…..
  Plains are extensive tracts of level or nearly level land. In
    North America, the plains extend from the southern
    Canadian prairie Provinces to Texas, and from the
    foothills of the Rocky Mountains in the west to the
    Mississippi River.

Mountains
   A mountain is a landform that extends above the
    surrounding terrain in a limited area. A mountain
    is generally much higher and steeper than a hill,
    but there is considerable overlap, and usage often
    depends on local custom. Some authorities define
    a mountain as a peak with a topographic
    prominence over an arbitrary value: for example,
    the Encyclopedia Britannica requires a
    prominence of 2,000 feet (610 m).

       Examples….
Plateau
   a plateau is an area of highland, usually consisting of
    relatively flat open country if the uplift was recent in
    geologic history. Plateaus, like mesas and buttes, are
    formed when land has been uplifted by tectonic activity
    and then eroded by wind or water. Flat-topped, sheer-
    sided plateaus, like the tepuis of Guiana, are formed
    when a section of land is uplifted that is topped with a
    layer of particularly resistant rock, and underlain by
    softer rock.

Hills
   landscapes features are moderately
    elevated in comparison to surrounding
