Study the images of Earth’s crust and mantle in two different areas. Item A shows a Lava source going through the Mantle and Crust, rising above Sea level to surface labeled Hawaii. Item B shows the Mantle beginning level on the left and dipping down on the right; the Crust is level on the left, labeled Great Valley of California, with mountains on the right, labeled Sierra Nevada and Mount Whitney. How is Item A different from Item B? The crust under the ocean in Item A is thicker than the crust under the mountain in Item B. The mantle under the ocean in Item A is thinner than the mantle under the mountain in Item B. The crust in Item A is found partially below sea level as compared to the crust in Item B. The mantle in Item A is located far below a mountain as compared to the mantle in Item B.

OMG it's very big question I think about it

explanation:

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.
