The earth's mantle is composed in part of minerals that contain iron:
The Earth's mantle is composed of rocks that have higher concentrations of mafic minerals (containing iron and magnesium) and lower in concentrations of the felsic minerals (aluminum and silica) than the rocks of Earth's crust.
The concentrations of the above elements therefore mean that the Earth's mantle is composed of a series of minerals that are predominately calcium / iron / magnesium aluminum silicates.
Such as:
- Olivine - (Mg,Fe)2SiO4
- Pyroxene - X(Si,Al)2O6, where X represents either calcium, sodium, iron or magnesium
- Spinel - MgAl2O4
- Garnet - X3Y2(SiO4)3 where X and Y can be a mixture of aluminum, iron, calcium, manganese or magnesium.
However the layers of the earth that are predominantly iron (approx 85 %) are the inner and outer core.
What else can I help you with?
Is the Earth's mantle iron?
No, the Earth's mantle is mostly made up of silicate minerals rather than iron. Iron is more abundant in the Earth's core.
Which of these is not a primary component of Earth's mantle?
Iron is not a primary component of the Earth's mantle. The main components of the mantle are silicon, oxygen, magnesium, and iron, with the dominant minerals being silicates.
What layer of the earth contains molten iron and nickel?
The outer core of the Earth contains molten iron and nickel. This layer is located beneath the Earth's mantle and is responsible for generating the planet's magnetic field.
Which element is not found in large quantities in Earth mantle?
Oxygen is not found in large quantities in the Earth's mantle as it is more abundant in the Earth's crust and atmosphere compared to the mantle. The most abundant elements in the Earth's mantle are oxygen, silicon, magnesium, and iron.
Which layer of earth contains iron rich silicate rock?
The layer of Earth that contains iron-rich silicate rock is the mantle. The upper mantle is composed of silicate minerals rich in iron and magnesium, such as olivine and pyroxene. This layer lies beneath the Earth's crust and extends to a depth of about 2,900 kilometers.
Is the Earth's mantle iron?
No, the Earth's mantle is mostly made up of silicate minerals rather than iron. Iron is more abundant in the Earth's core.

What layer of earth made mostly of iron?

What layer of the earth contains molten iron and nickel?
The outer core of the Earth contains molten iron and nickel. This layer is located beneath the Earth's mantle and is responsible for generating the planet's magnetic field.
What consist of the Earth's crust?
iron in the core,the mantle is a mix of magnesium, silicon, iron, and oxygen.
Which element is not found in large quantities in Earth mantle?
Oxygen is not found in large quantities in the Earth's mantle as it is more abundant in the Earth's crust and atmosphere compared to the mantle. The most abundant elements in the Earth's mantle are oxygen, silicon, magnesium, and iron.
Which layer of earth contains iron rich silicate rock?
The layer of Earth that contains iron-rich silicate rock is the mantle. The upper mantle is composed of silicate minerals rich in iron and magnesium, such as olivine and pyroxene. This layer lies beneath the Earth's crust and extends to a depth of about 2,900 kilometers.
Is liquid iron found in the lower mantle?
No. Liquid iron is found in the outer core. There are distinct layers in the earth.
Three main layers thay make up earth are?
The three main layers of the earth are the Core, Mantle and Crust. The Core is mostly made from iron and nickel, the Crust from oxygen, silicon and aluminum and the mantle silicon,oxygen,iron and magnesium.
What is the most abundant element in mantle?
The most abundant element in Earth's mantle is oxygen, which combines with other elements such as silicon, magnesium, and iron to form the majority of minerals found in the mantle. Oxygen makes up about 44% of the mantle by weight.
What is the largest layer of earth's surface composed mostly of silicon oxygen magnesium and iron?
it's mantle
