Even in the 21st century, some confusion remains as to exactly what physiography is. One source states Geomorphology includes quaternary geology, physiography and most of physical geography, treating physiography as a separate field, but subservient to geomorphology.
Yuppie (/ËjÊpi/; short for young urban professional or young upwardly-mobile professional) is a term that was introduced in the early 1980s and is defined by the Oxford English Dictionary as an individual who is a member of a socio-economic group comprising young professional people working in cities..
These classification groups are often given arbitrary names: ?A YUPPIE is someone over the age of 18 with a college degree who has a home valued at more than $300,000, a gross income of at least $100,000 per year?.r. Kimball coined the term? behavior tags? to describe the process of identifying participation in clusters. Kimball notes that participation on a cluster is time-based, and someone can be a YUPPIE one year and then change groups as their income or occupation changes.
