The table below shows the elements that mainly comprise each of the four layers of Earth:

Elements in Layers
Layer Main Elements
Crust Oxygen, Silicon
Mantle Iron, Magnesium
Outer Core Iron, Nickel
Inner Core Iron


Which of these elements make up the layer that is 0.2 to 1.1 percent of Earth's total diameter?
Oxygen and Silicon
Iron and Magnesium
Iron and Nickel
Magnesium and Silicon

Answer 1

oxygen and silicone. The crust consists of tectonic plates (in relative motion one from another) and has 5–70 km (~3–44 miles) in depth. The most abundant elements of this layer are: oxygen-46.6 percent by weight; silicon-27.7 percent; aluminum-8.1 percent; iron-5 percent.
