Oceanic crust.
The largest layer of Earth's surface that is composed mostly of silicon, oxygen, magnesium, and iron is the mantle. The mantle is located between the Earth's crust and core and makes up about 84% of Earth's volume.
The largest layer in Earth's surface composed mostly of silicon, oxygen, magnesium, and iron is the mantle. The Earth's mantle is a solid-rock layer that lies between the crust and the core. It is rich in minerals such as olivine, pyroxene, and feldspar, which contain these elements.

Peridot is gem-quality olivine. As such it contains magnesium, iron, silicon, and oxygen.
Talc is not classified as a metal. It is a very soft hydrous silicate mineral composed of magnesium, silica and water
The layer of moon that is composed of magnesium, iron,silicon (not silica) is called Crust.It is outermost layer of the moon. It also contains Calcium,Aluminum and Oxygen.
Silicon is not converted to magnesium in earth; some artificial isotopes of silicon decay to magnesium isotopes.
Yes, all silicate materials contain oxygen and silicon. Silicates are compounds composed of silicon and oxygen atoms, often combined with other elements such as aluminum, iron, magnesium, or potassium. They form the largest group of minerals on Earth.
No, carbonates do not contain silicon. Carbonates are composed of carbon and oxygen, typically combined with a metal such as calcium, magnesium, or iron. Silicon is a separate element found in silicate minerals.
Among magnesium, silicon, sulfur, and sodium, sodium has the largest atomic radius. This is due to its position in the periodic table; sodium is an alkali metal with a larger atomic radius compared to the other elements, which are nonmetals or metalloids. As you move down a group in the periodic table, the atomic radius increases, and sodium is lower in its group than magnesium, silicon, and sulfur. Thus, sodium has the largest radius of the four elements.
The largest layer of the Earth is the mantle, composed mainly of silicon, oxygen, magnesium, and iron. It lies between the outer core and the Earth's crust, extending down to about 2,900 kilometers below the Earth's surface. The mantle plays a crucial role in the movement of tectonic plates and the convection currents that drive plate tectonics.
