The answer to the riddle

Here is the answer to this riddle:

I am the home of Polar Bears
And all the Esquimaux
I serve as roads for Camels
And Tibetans in the snow
The deepest of the Canyons
Is a Wrinkle in my Face
The sand-dunes in the Desert
Are my hand-embroidered Lace
I sing in Great Upheavals
That sometimes destroy Towns,
I can raise up Islands
And also bring them Down.

EARTH!
