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.
Kinds of Crust. The crust is the thinnest of the Earthâs three layers and the top part of the lithosphere. It is only about 8 kilometers (5 miles) thick under the oceans and 32 kilometers (20 miles) beneath continents. The rocks in the crust are primarily made of oxygen, silicon, aluminum and iron.ore About the Mantle. The crust is an important part of the lithosphere, but below it lies the other component: the top part of the upper mantle. This is denser than the crust. Like the crust, it contains rocks with large amounts of silicon and oxygen, but the mantle also has significant amounts of iron and magnesium.
