Height is the measure ___MASK22___ vertical distance , either how " tall " something is , or how " high up " it is . For example " The height ___MASK22___ the building is 50 m " or " The height ___MASK22___ the airplane is 10 , 000 m ". When used to describe how high something like an airplane or mountain peak is from sea level , height is more often called altitude . Height is measured along the vertical ( y ) axis between a specified point and another . In aviation and aviation meteorology , a flight level ( FL ) is defined as a vertical altitude at standard pressure , nominally expressed in hundreds ___MASK22___ feet . The pressure is computed assuming an International standard sea - level pressure datum ___MASK22___ 1013 . 2 hPa ( 29 . 92 inHg ), and therefore is not necessarily the same as the aircraft ' s actual altitude either above mean sea level or above ground level . ___MASK52___ (" Athína " ) is the capital and largest city ___MASK22___ Greece . ___MASK52___ dominates the Attica region and is one ___MASK22___ the world ' s oldest cities , with its recorded history spanning over 3 , 400 years , and its earliest human presence starting somewhere between the 11th and 7th millennia BC . Classical ___MASK52___ was a powerful city - state that emerged in conjunction with the seagoing development ___MASK22___ the port ___MASK22___ Piraeus , which had been a distinct city prior to its 5th century BC incorporation with ___MASK52___ . A centre for the arts , learning and philosophy , home ___MASK22___ Plato ' s Academy and Aristotle ' s Lyceum , it is widely referred to as the cradle ___MASK22___ Western civilization and the birthplace ___MASK22___ democracy , largely because ___MASK22___ its cultural and political impact on the European continent , and in particular the Romans . In modern times , ___MASK52___ is a large cosmopolitan metropolis and central to economic , financial , industrial , maritime , political and cultural life in Greece . In 2015 , ___MASK52___ was ranked the world ' s 29th richest city by purchasing power and the 67th most expensive in a UBS study . Mean sea level ( MSL ) ( abbreviated simply sea level ) is an average level ___MASK22___ the surface ___MASK22___ one or more ___MASK22___ Earth ' s oceans from which heights such as elevations may be measured . MSL is a type ___MASK22___ vertical datuma standardised geodetic reference pointthat 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 in order to calibrate altitude and , consequently , aircraft flight levels . A common and relatively straightforward mean sea - level standard is the midpoint between a mean low and mean high tide at a particular location . ___MASK51___ is a municipality in the Kozani regional unit , Greece . The seat of the municipality is the town Ptolemaida . The municipality has an area of 708 . 807 km . The population was 45 , 592 in 2011 . ___MASK96___ is a continent that comprises the westernmost part ___MASK22___ Eurasia . ___MASK96___ is bordered by the Arctic Ocean to the north , the ___MASK2___ to the west , and the Mediterranean Sea to the south . To the east and southeast , ___MASK96___ is generally considered as separated from Asia by the watershed divides ___MASK22___ the Ural and Caucasus Mountains , the Ural River , the Caspian and Black Seas , and the waterways ___MASK22___ the Turkish Straits . Yet the non - oceanic borders ___MASK22___ ___MASK96___  a concept dating back to classical antiquity  are arbitrary . The primarily physiographic term " continent " as applied to ___MASK96___ also incorporates cultural and political elements whose discontinuities are not always reflected by the continent ' s current overland boundaries . Mouriki is a former municipality in ___MASK66___ , West Macedonia , Greece . Since the 2011 local government reform it is part ___MASK22___ the municipality ___MASK51___ , ___MASK22___ which it is a municipal unit . The municipal unit has an area ___MASK22___ 112 . 058 km . The population in 2011 was 3 , 909 . The seat ___MASK22___ the municipality was in Emporio . Atmospheric pressure , sometimes also called barometric pressure , is the pressure exerted by the weight ___MASK22___ air in the atmosphere ___MASK22___ Earth ( or that ___MASK22___ another planet ). In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight ___MASK22___ air above the measurement point . Low - pressure areas have less atmospheric mass above their location , whereas high - pressure areas have more atmospheric mass above their location . Likewise , as elevation increases , there is less overlying atmospheric mass , so that atmospheric pressure decreases with increasing elevation . On average , a column ___MASK22___ air in cross - section , measured from sea level to the top ___MASK22___ the atmosphere , has a mass ___MASK22___ about and weight ___MASK22___ about . That force ( across one square centimeter ) is a pressure ___MASK22___ 10 . 1 N / cm or 101 , 000 N / m . A column in cross - section would have a weight ___MASK22___ about or about 65 . 4 N . Anarrachi ( Greek :  , Macedonian :  , Turkish : Debre ) is a small town in the Mouriki municipal unit , northern ___MASK66___ , Greece . It is situated at an altitude ___MASK22___ 710 meters above sea level . The postal code is 50005 , and the telephone code is + 30 24630 . The census was 1 , 151 at the 1991 census . The euro ( sign : €; code : EUR ) is the official currency ___MASK22___ the eurozone , which consists ___MASK22___ 19 ___MASK22___ the member states ___MASK22___ the European Union : Austria , Belgium , Cyprus , Estonia , Finland , France , Germany , Greece , Ireland , Italy , Latvia , Lithuania , Luxembourg , Malta , the Netherlands , Portugal , ___MASK65___ , Slovenia , and Spain . The currency is also officially used by the institutions ___MASK22___ the European Union and four other European countries , as well as unilaterally by two others , and is consequently used daily by some 337 million Europeans . Outside ___MASK22___ Europe , a number ___MASK22___ overseas territories ___MASK22___ EU members also use the euro as their currency . Altitude or height ( sometimes known as depth ) is defined based on the context in which it is used ( aviation , geometry , geographical survey , sport , and many more ). As a general definition , altitude is a distance measurement , usually in the vertical or " up " direction , between a reference datum and a point or object . The reference datum also often varies according to the context . Although the term altitude is commonly used to mean the height above sea level ___MASK22___ a location , in geography the term elevation is often preferred for this usage . Cartography ( from Greek  " kharts ", " papyrus , sheet ___MASK22___ paper , map "; and  " graphein ", " write ") is the study and practice ___MASK22___ making maps . Combining science , aesthetics , and technique , cartography builds on the premise that reality can be modeled in ways that communicate spatial information effectively . Aviation is the practical aspect or art ___MASK22___ aeronautics , being the design , development , production , operation and use ___MASK22___ aircraft , especially heavier than air aircraft . The word " aviation " was coined by French writer and former naval officer Gabriel La Landelle in 1863 , from the verb " avier " ( synonymous flying ), itself derived from the Latin word " avis " (" bird ") and the suffix "- ation ". Tides are the ___MASK33___ and fall ___MASK22___ sea levels caused by the combined effects ___MASK22___ the gravitational forces exerted by the Moon and the Sun and the rotation ___MASK22___ the Earth . The elevation ___MASK22___ a geographic location is its height above or below a fixed reference point , most commonly a reference geoid , a mathematical model ___MASK22___ the Earth ' s sea level as an equipotential gravitational surface ( see Geodetic system , vertical datum ). Elevation , or geometric height , is mainly used when referring to points on the Earth ' s surface , while altitude or geopotential height is used for points above the surface , such as an aircraft in flight or a spacecraft in orbit , and depth is used for points below the surface . Standard sea level ( SSL ) ( also known as " sea level standard " ( SLS )) defines a set ___MASK22___ conditions for physical calculations . The term " standard sea level " is used to indicate that values ___MASK22___ properties are to be taken to be the same as those standard at sea level , and is done to define values for use in general calculations . ___MASK45___ (' ), officially the Hellenic Republic ( Greek : ' ), historically also known as Hellas ("" ), is a country in southeastern Europe . ___MASK45___ ' s population is approximately 10 . 955 million as ___MASK22___ 2015 . Athens is the nation ' s capital and largest city , followed by Thessaloniki . A chart datum is the level ___MASK22___ water that charted depths displayed on a nautical chart are measured from .
