| A basic unit of geographic study is the region, an
area on the earth’s surface that is defined by certain unifying
characteristics. Geographers use regions to describe, explain, and analyze
the physical environment. Brazil is divided into five regions, based on
broadly similar features, with perimeters following state boundaries.
Climate, soil, and natural vegetation are the three physical features used
to define each region. Brazil
is divided into five regions: the north, the Northeast, Center West, the
Southeast and the South. 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. Using the
theme of regions, geographers divide the world into manageable units for
study.
