A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (980 ft) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges.
Atmospheric pressure, also known as air pressure or barometric pressure, is the pressure within the atmosphere of Earth. The standard atmosphere is a unit of pressure defined as 101,325 Pa (1,013.25 hPa), which is equivalent to 1,013.25 millibars, 760 mm Hg, 29.9212 inches Hg, or 14.696 psi. The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth; that is, the Earth's atmospheric pressure at sea level is approximately 1 atm.
The horizon is the apparent curve that separates the surface of a celestial body from its sky when viewed from the perspective of an observer on or near the surface of the relevant body. This curve divides all viewing directions based on whether it intersects the relevant body's surface or not.
Altitude is a distance measurement, usually in the vertical or "up" direction, between a reference datum and a point or object. The exact definition and reference datum varies according to the context. Although the term altitude is commonly used to mean the height above sea level of a location, in geography the term elevation is often preferred for this usage.
Mean sea level is an average surface level of one or more among Earth's coastal bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datum – a standardised geodetic datum – that is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is instead the midpoint between a mean low and mean high tide at a particular location.
In geology and physical geography, a plateau, also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the surrounding area on at least one side. Often one or more sides have deep hills or escarpments. Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, and erosion by water and glaciers. Plateaus are classified according to their surrounding environment as intermontane, piedmont, or continental. A few plateaus may have a small flat top while others have wider ones.
Valmeinier is a commune in the Savoie department in the Auvergne-Rhône-Alpes region in south-eastern France.
Metres above the Adriatic is the vertical datum used in Austria, in the former Yugoslavian states of Slovenia, Croatia, Bosnia-Hercegovina, Serbia, Montenegro, North Macedonia, as well as in Albania to measure elevation, referring to the average water level of the Adriatic Sea at the Sartorio mole in the Port of Trieste.
Mont d'Ambin or Rocca d'Ambin is a mountain on the border of Savoie, France and of the Province of Turin, Italy. It lies in the Ambin group of the Cottian Alps. On the Italian side, it commands the view of the Val di Susa. It has an elevation of 3,378 metres (11,083 ft) above sea level. The Mont d'Ambin base tunnel of the Lyon–Turin rail link is being dug at its base.
Aiguille de Scolette or Pierre Menue is a mountain of Savoie (F) and of the province of Turin (I). It lies in the Cottian Alps and has an elevation of 3,506 metres above sea level.
The Sumatran giant shrew is a shrew of the genus Crocidura. It is native to the Indonesian island of Sumatra, where it is found both in the rainforests to the west of the island and in the hillsides in the south and east. The shrew can be found up to approximately 2,000 metres (6,600 ft) above sea level but is most common at 1,500–1,800 metres (4,900–5,900 ft) above sea level.
A steep coast is a stretch of coastline where the mainland descends abruptly into the sea. There is a sharp transition from the land to sea as opposed to that on a flat coast where the land descends gradually seawards. The height of the land on a steep coast is well above sea level.
Pointe de Paumont or Cima del Vallone is a mountain of Savoie, France and of the Province of Turin, Italy. It lies in the Cottian Alps range. It has an elevation of 3,171 metres above sea level.
Punta Bagnà or Cime du Grand Vallon is a mountain of Savoie, France and of the Province of Turin, Italy. It lies in the Cottian Alps range. It has an elevation of 3,129 metres above sea level.
Punta Sommeiller or Pointe Sommeiller is a mountain of the Province of Turin, Italy and of Savoie, France. It lies in the Cottian Alps range. It has an elevation of 3,333 metres (10,935 ft) above sea level.
Rognosa d'Etiache or Rognosa d'Étache is a mountain in the Cottian Alps on the border of Turin, Italy, and Savoie, France. It has an elevation of 3,382 metres above sea level.
The Pic du Thabor is a mountain of Savoie and Hautes-Alpes, France. It lies in the Massif des Cerces range. It has an elevation of 3,207 metres above sea level, it stands closed to another summit, the Mont Thabor, culminating at 3,178 metres above sea level.
Granite Vale is a rural locality in the City of Townsville, Queensland, Australia. In the 2016 census, Granite Vale had a population of 0 people.
Height above mean sea level is a measure of the vertical distance of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as orthometric heights.
