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.
Quick Answer. The Earth's crust is solid matter. Both oceanic and continental crusts are made entirely of rock. The former is primarily composed of denser material such as basalt, and it is, on average, 4 miles thick. In contrast, the continental crust is generally made up of lighter rock such as granite.
