The Atacama Desert is one of the most driest places on Earth.
Though flanked on one side by the Pacific Ocean and by the
snow-capped Andes on the other, very little of water ever
reaches this remote area, which it extends for thousands of
kilometres through northern Chile and up into Peru. In some
places, there must has been no rain for hundreds of years,
certainly since the Spanish conquest of the sixteenth century
and possibly even more longer. Near the coast, however, some
water gets to the few only plants that can survive there, but
in the form of fog, not rain. these plants can have adapted
to the conditions by taking moisture from the air when the
clouds roll in from the Pacific. Further south, in all the less
arid region, the parched brown earth now and also then
undergoes a remarkable change when the rain comes and the
phenomenon that known as the "flowering desert" occurs.
Suddenly, purple, yellow and blue flowers spring up from
seeds, which forming a spectacular sight, but one that
occurs only about once every other four years.
