Nickel is present generally, but is much lower in the crust relative to its distribution throughout, Potassium is eighth in abundance for the crust, but lower than 0.2% in general, The predominance of iron in the whole earth is largely due to it being >33% in the earth s core. The large amount of oxygen in the Earth s crust is largely due to the fact that nearly all of the metals in the Earth s crust are combined with oxygen. The crust is the lightest layer due to its predominance of the smaller elements oxygen and silicon. This lower density allows it to float and move resulting in what we called plate tectonics..", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
