A) River flood plain

B) Desert

C) Valley

D) Delta

ANSWER

The correct option is B.

A desert refers to a place that experiences very little rainfall on a yearly basis, thus, living conditions are harsh for the plants and animals that live in such an environment. Scientists have found out that, approximately one third of the earth surface are deserts. Water is very essential for the survival and flourishing  of plants and animals and it is a scarce commodity in deserts, thus, a desert can not support high density population.

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
