Lake Titicaca, Bolivia and
Peru (NASA, June 1993).
The largest freshwater lake in South America, can be seen in this low-oblique,
southeast-looking photograph. Lake Titicaca is located in a depression in the
Altiplano (high plains) between the eastern (greenish, forest-covered mountains
east of the lake, partially obscured by clouds) and the western (brownish area
west of the lake with numerous volcanic peaks) range of the Andes Mountains.
Lake Titicaca covers an area of 8300 km², is nearly 190 km long, and has an
average width of 72 km. Fed by many mountain streams that border the Altiplano,
the lake is drained only by the Desaguadero River, which flows south into Lake
Poopó (not visible in the photograph). Water levels can vary as much as 5 m
from season to season and year to year. Much of the lake water is lost through
evaporation caused by intense sunshine and strong winds. Since the late 1980s,
drought has plagued this region of the Altiplano, causing water levels in the
lake to drop below normal. The whitish areas scattered around the lakeshore are
newly exposed lake bottom areas. A small tail-like portion at the northern end
of the lake (visible in the photo) has been cut off from the main body of
the lake because the water level has receded. Drastic drops in water level in
the lake could eventually affect the moderating climate of this high-altitude
lake 3800 m above sea level, which could lead to reduced agricultural crop
yields. The agricultural crops of wheat and maize help sustain many Indians that
live along Lake Titicaca’s shores.
America is a continent made up of four parts:
North America, Central America, South America
and the Antilles. South America was the
original New World and the original America in the early 16th century. These
designations were extended later to the rest of the continent. The name AMERICA
was first placed in Brazil in 1507.
