Answer 1

"THEME 5: REGIONS

A basic unit of geographic study is the region, an area on the earth’s surface that is defined by certain unifying characteristics. The unifying characteristics may be physical, human, or cultural. In addition to studying the unifying characteristics of a region, geographers study how a region changes over times.
