Foothills or piedmont are geographically defined as gradual increases in elevation at the base of a mountain range, higher hill range or an upland area. They are a transition zone between plains and low relief hills and the adjacent topographically higher mountains, hills, and uplands. [1] Frequently foothills consist of alluvial fans, coalesced alluvial fans, and dissected plateaus.
Foothills primarily border mountains, especially those which are reached through low ridges that increase in size closer and closer to the mountain, [2] but can also border uplands and higher hills. [3]
Areas where foothills exist, or areas commonly referred to as the foothills, include the:
Another word for a foothill region is "piedmont", derived from "foot of the mount" in Romance languages. [4] The Piedmont region of Italy lies in the foothills of the Alps, and several other foothills in other parts of the world are called "piedmont", and include:
Ecosystems of piedmonts (foothills) are often known as submontane zones, relating to the higher montane ecosystems.
The Appalachian Mountains, often called the Appalachians, are a mountain range in eastern to northeastern North America. The term "Appalachian" refers to several different regions associated with the mountain range, and its surrounding terrain. The general definition used is one followed by the United States Geological Survey and the Geological Survey of Canada to describe the respective countries' physiographic regions. The U.S. uses the term Appalachian Highlands and Canada uses the term Appalachian Uplands; the Appalachian Mountains are not synonymous with the Appalachian Plateau, which is one of the provinces of the Appalachian Highlands.
Upland or Uplands may refer to:
Rapti Zone was one of the fourteen zones, located in the Mid-Western Development Region of Nepal. It was named after the West Rapti River which drains Rolpa, Pyuthan and part of Dang districts. The remainder of Dang and part of Salyan district are drained by the Babai. The remainder of Salyan and all of Rukum districts are drained by the Bheri.
The Great Basin Desert is part of the Great Basin between the Sierra Nevada and the Wasatch Range. The desert is a geographical region that largely overlaps the Great Basin shrub steppe defined by the World Wildlife Fund, and the Central Basin and Range ecoregion defined by the U.S. Environmental Protection Agency and United States Geological Survey. It is a temperate desert with hot, dry summers and snowy winters. The desert spans large portions of Nevada and Utah, and extends into eastern California. The desert is one of the four biologically defined deserts in North America, in addition to the Mojave, Sonoran, and Chihuahuan Deserts.
Orographic lift occurs when an air mass is forced from a low elevation to a higher elevation as it moves over rising terrain. As the air mass gains altitude it quickly cools down adiabatically, which can raise the relative humidity to 100% and create clouds and, under the right conditions, precipitation.
The Piedmont is a plateau region located in the Eastern United States. It is situated between the Atlantic Plain and the Blue Ridge Mountains, stretching from New York in the north to central Alabama in the south. The Piedmont Province is a physiographic province of the larger Appalachian Highlands physiographic division and consists of the Piedmont Upland, and the Piedmont Lowlands sections.
Piedmont is a region in Northwest Italy.
The Shephelah or Shfela, or the Judaean Foothills, is a transitional region of soft-sloping rolling hills in south-central Israel stretching over 10–15 km (6.2–9.3 mi) between the Judaean Mountains and the Coastal Plain. The different use of the term "Judean Plain", as either defining just the Coastal Plain segment stretching along the Judaean Mountains, or also including, or only referring to, the Shfela, often creates grave confusion.
Highlands or uplands are areas of high elevation such as a mountainous region, elevated mountainous plateau or high hills. Generally, upland refers to a range of hills, typically from 300 m (980 ft) up to 600 m (2,000 ft), while highland is usually reserved for ranges of low mountains. However, the two terms are interchangeable and also include regions that are transitional between hilly and mountainous terrain.
Western North Carolina is the region of North Carolina which includes the Appalachian Mountains; it is often known geographically as the state's Mountain Region. It contains the highest mountains in the Eastern United States, with 125 peaks rising to over 5,000 feet in elevation. Mount Mitchell at 6,684 feet, is the highest peak of the Appalachian Mountains and mainland eastern North America. The population of the 23 most commonly associated counties for the region, as measured by the 2020 U.S. Census, is 1,149,405. The region accounts for approximately 11% of North Carolina's total population.
The Upland South and Upper South are two overlapping cultural and geographic subregions in the inland part of the Southern United States. They differ from the Deep South and Atlantic coastal plain by terrain, history, economics, demographics, and settlement patterns.
Cane Creek Mountains is a small mountain range that lies south of Burlington, North Carolina. The range covers an area including Alamance County, Guilford County, Randolph County, and Chatham County in North Carolina.
The U.S. state of Tennessee is geographically diverse, with varying terrains and several distinct physiographic regions. Its landforms range from the Blue Ridge Mountains in the eastern part of the state to flat and fertile plains along the Mississippi River. The state is geographically, legally, culturally, and economically divided into three Grand Divisions: East Tennessee, Middle Tennessee, and West Tennessee.
The Northern Basin and Range ecoregion is a Level III ecoregion designated by the United States Environmental Protection Agency (EPA) in the U.S. states of Oregon, Idaho, Nevada, Utah, and California. It contains dissected lava plains, rolling hills, alluvial fans, valleys, and scattered mountain ranges in the northern part of the Great Basin. Although arid, the ecoregion is higher and cooler than the Snake River Plain to the north and has more available moisture and a cooler climate than the Central Basin and Range to the south. Its southern boundary is determined by the highest shoreline of Pleistocene Lake Bonneville, which once inundated the Central Basin and Range. The western part of the region is internally drained; its eastern stream network drains to the Snake River system.
A Mittelgebirge is a type of relatively low mountain range or highland area typical of the geography of central Europe, especially central and southern Germany; it refers to something between rolling low hill country or Hügelland and a proper mountain range like the High Alps.
The Piedmont Mountains are a series of outlying mountain ranges, sometimes called “low mountains”, in the Eastern United States, mostly in the western Piedmont near the Blue Ridge Mountains. The Piedmont is part of the greater Appalachian Mountain Range. The French definition of piedmont is "foothill"; however, a Piedmont Mountain is often of greater significance or prominent elevation.
The Northeastern Highlands Ecoregion is a Level III ecoregion designated by the United States Environmental Protection Agency (EPA) in the U.S. states of Vermont, New Hampshire, Massachusetts, Maine, Connecticut, New York, New Jersey, and Pennsylvania. The ecoregion extends from the northern tip of Maine and runs south along the Appalachian Mountain Range into eastern Pennsylvania. Discontiguous sections are located among New York's Adirondack Mountains, Catskill Range, and Tug Hill. The largest portion of the Northeastern Highlands ecoregion includes several sub mountain ranges, including the Berkshires, Green Mountains, Taconic, and White Mountains.
