1Landform Regions of North Carolina and Maps & Aerial Photographs 2.06 Identify and use models, maps, and aerial photographs as ways of representing landforms.
2Landform Regions of North Carolina North Carolina has a variety of landforms: mountains, plains, plateaus, and coastline.The state is divided into three distinct topographical regions. Eastern North Carolina is the Coastal Plain (sometimes subdivided into an Inner Coastal Plain and Tidewater region), west of the Coastal Plain is the Piedmont Plateau (a.k.a. Piedmont), and Western North Carolina consists of the Mountains.
3MountainsThe Appalachian Mountains--including Mount Mitchell, the highest peak in Eastern North America (6,684 feet)-- add to the variety which is apparent in the state's topography. More than 200 mountains rise 5,000 feet or more.Piedmont Plateau (a.k.a. Piedmont)The Piedmont (meaning literally "foot of the mountain"), is home to a diverse mixture of agriculture, government, manufacturing, research, and technology development. The six largest cities in North Carolina, and eight of the top ten, are in this region of the state, the exceptions being Wilmington on the Coastal Plain and Asheville in the Appalachian Mountains. The southeastern section of the Piedmont is known as the Sandhills, and is known for its nationally famous golf courses and stables.
4Coastal Plain (Inner Coastal Plain and Tidewater) The Coastal Plain offers opportunities for farming, recreation, and manufacturing. Large forested areas, mostly pine, support pulp manufacturing and other forest-related industries. Thousands of tourists visit the state's many beaches. The North Carolina coast is protected by a slender chain of islands known as the Outer Banks. The Piedmont Plateau is sharply divided from the Inner Coastal Plain at the Fall Line. The Fall Line is a quick descent, and it is the site of many river rapids and waterfalls. At the bottom of the Fall Line, you find the Sandhills. The Sandhills is a region in the interior of the U.S. states of North Carolina and South Carolina. It is a strip of ancient beach dunes which generally divides the Piedmont from the coastal plain, and is the evidence of a former coastline when the ocean level was higher, or the land lower.
5Geological FeaturesMaps give us information about the physical features of the Earth. There are many different kinds of maps, including topographic maps and aerial maps. Topographic maps show the shape and features of the land. These maps show the contour, or shape, of the land, as well as the elevation, or height of different parts of the land. Topographic maps also show special features, like rivers and streams.
6Topographic MapA topographic map uses contour lines to show points that are on the same level.
7How Do You Read Topographic Maps? Topographic maps use contour lines to show the shape of Earth’s surface. A contour line is an imaginary line drawn on a map. It connects points of equal height above or below sea level. Sea level is the mean level of the surface of the sea between high and low tides and is considered as 0 elevation.
8The spacing of contour lines indicates how steep a slope is The spacing of contour lines indicates how steep a slope is. Contour lines that are farther apart indicate a gentler slope. Contour lines that are closer together indicate a steeper slope.Bodies of water, such as oceans, rivers, and lakes, are also indicated on topographic maps. Symbols are used to locate forests, roads, railroad tracks, and buildings.
9Shaded relief maps indicate height by using shading instead of contour lines. The shading makes it easier to recognize sloping hills, steep mountains, and deep valleys. Some topographic maps combine shaded relief maps with contour lines to give an even clearer idea of the geology of an area.
