It is a silvery-white, soft, nonmagnetic, ductile metal. Aluminum Wikipedia https://en.wikipedia.org/wiki/Aluminium https://en.wikipedia.org/wiki/Altitude Wikipedia Altitude or height (sometimes known as depth) is defined based on the context in which it is used (aviation, geometry, geographical survey, sport, atmospheric pressure, 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 of a location, in geography the term elevation is often preferred for this usage.
