The Sahara

The Atacama

Just west of South America’s Atacama


Desert is the largest body of water in the
world—the Pacific Ocean . The Atacama lies
along the Pacific Coast, squeezed in a narrow
band between the ocean and the high Andes
Mountains . Temperatures in the Atacama are
pleasant, between 50° and 70°F (10°–20°C) .
One would think that being near the ocean
would give the Atacama some moisture,
but this desert is possibly the driest place on
Earth . In some places in the Atacama, it may
have never rained in human memory . Many people in the Sahara Desert still rely on camels.

Many parts of the Gobi are high, dry, and
mountainous . The soil is rocky and salty, so
there are few plants other than tough grasses
and shrubs . But these grasses are enough to
support grazing animals such as Mongolian
horses, antelope, and gazelle . Also feeding
on the grasses are many kinds of gerbils and
