Very few I suspect. My hope for Amal is that this scary-skinny phase is a passing one and she'll relax into her marriage and return to the lovely, wonderfully winsome creature whom Clooney fell in love with. She doesn't need to be an alpha female competing with other women. She's already won the jackpot.
Earth's crust is Earth's hard outer layer. It is less than 1% of Earth's volume. The crust is made up of different types of rocks: igneous, metamorphic, and sedimentary rocks. Below the crust is the mantle. The upper part of the mantle is made up of peridotite, a rock denser than rocks common in the crust. The crust and the upper mantle make up the lithosphere.
The Earth's Crust. At the very surface of the Earth is the crust, the topmost layer, made mostly out of solid silicate rocks like basalt and granite. The crust is like the icing on a cake, though not nearly so tasty. We humans live on top of the crust; you can think of us as the strawberries or gummy bears on the top of the cake.
