Crust (geology) only planet in our Solar System with plate tectonics. The crust is a thin shell on the outside of the Earth, accounting for less than 1% of Earth's volume. It is the top component of lithosphere: a division of Earth's layers that includes the crust and the upper part of the mantle. The lithosphere is broken into tectonic plates that move, allowing heat to escape from the interior of the Earth into space. The crust lies on top of the mantle, a configuration that is stable because the upper mantle is made of peridotite and so is significantly denser than
Salt crust Salt crust Salt crust is the name given to the method of covering of an ingredient, commonly fish such as sea bass and grouper, in a sand-like mixture of usually egg whites and salt. The salt acts as insulation and helps cook the food in an even and gentle manner. After baking, the golden-brown shell is cracked, resulting in moist and evenly cooked food. The technique is used often with chefs as it simultaneously roasts, steams and seasons. Traditionally fish is seen most commonly using the salt crust method to be baked but in recent times with salt becoming much
