Erosion by wind can cause immense, choking dust clouds. Dry weather and reduction in ground cover can cause dangerous loss of soil to wind.
false
true

they disappear through years
They are deposited far away
in some places the wind also deposits sand. The result is huge sand dunes such as those in Death Valley, California, and White Sands, New Mexico--quiet monuments to the never-ending force of erosion.
