Earth's crust - thickness:
Crustal thickness maps: Global, another, 2° North America; histograms Maximum thickness results from a "double" crust - one plate pushed under another. |

This image is only very roughly aligned with the one below.
source This diagram stops at sea level - land surface height is not shown. :( Eg, Everest is this high.
Pacific crust decending under Oregon Info here.
There is a scale map on the floor.
Numbers are density (g/cm^3) - light rock floats higher. You can see the thin blue ocean upper left. <- West, East -> The "-100" depth under "Oregon" is a typo - it should of couse be "0". |
