Brazil covers almost half of the South American continent. It is
bordered to the north, west and south by all South American countries
except Chile and Ecuador, to the east is the Atlantic.
The country is relatively flat with over 60% of the country consisting
of plateau. Its largest city is Sao Paulo, and its capital is Brasilia.
The climatic pattern is largely shaped by Brazil's tropical location
and by topographic features. Most of Brazil has high annual average
temperatures, above 22° C (72° F).
Only in the South and in the highest elevations does the average
fall below this. In the higher elevations, the seasonal variation
in temperature is more marked.
