Height is the measure of vertical distance, but has two meanings in common use. It can either indicate how "tall" something is, or how "high up" it is. For example "The height of the building is 50 m" or "The height of 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 . ==Etymology== English ''high'' is derived from Old English ''hēah'', ultimately from Proto-Germanic *''xauxa-z'', from a PIE base '' *keuk-''. The derived noun ''height'', also the obsolete forms ''heighth'' and ''highth'', is from Old English ''híehþo'', later ''héahþu'', as it were from Proto-Germanic '' *xaux-iþa''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「height」の詳細全文を読む スポンサード リンク
