B

Deserts are found where there is little rainfall or where rain for a whole year falls

in only a fewweeks' time. Ten inches of rain may be enough for many plants to

survive (存活)if the rain is

spread throughout the year, If it falls, within one or two months and the rest of the

year is dry, thoseplants may die and a desert may form.

Sand begins as tiny pieces of rock that get smaller and smaller as wind and

weather wear themdown. Sand dunes (沙丘) are formed as winds move the sand

across the desert. Bit by bit, the

dunes grow over the years, always moving with the winds and changing the shape.

Most of them areonly a few feet tall, but they can grow to be several hundred feet

high. southwestern UnitedStates, cliffs (悬崖) and deep valleys were formed from thick

mud that once lay beneath a sea more than millions of years ago. Over the centuries,

the water dried up. Wind, sand , rain, heat and cold all wore away at the remaining

rocks. The faces of the desert mountains are always changing –-very, very slowly ---

as these forces of nature continue to work on the rock.

Most desertshave a surprising variety of life. There are plants, animals and

insects that :haveadapted to life in the desert. During the heat of the day, a visitor

may see very few signs of livingthings, but as the air begins to cool in the evening,

the desert comes to life. As the sun begins torise again in the sky, the desert once

again becomes quiet and lonely.
