Which Layer of the Earth is the Most Dense
The Earth is made up of different layers, each with its own density. The densest layer is the inner core, followed by the outer core, the mantle, and finally the crust. The inner core is made up of iron and nickel and is under immense pressure from the weight of the overlying layers.
This pressure causes the iron to be in a solid state even though it has a melting point of around 1500°C. The outer core is also made up mostly of iron but also contains some lighter elements such as sulfur and oxygen. This layer is also under great pressure but not as much as the inner core so it exists in a liquid state.
Why is the Earth’s core so dense?
The Earth’s mantle is the most dense layer of the planet. The mantle is made up of solid rock and is about 2,900 kilometers (1,800 miles) thick. It makes up 84% of Earth’s volume.
The outer core is less dense than the mantle but is still very dense. It is a liquid layer of iron and nickel that is about 2,200 kilometers (1,400 miles) thick.
Which Layer of Earth is the Densest And Why is That So
The innermost layer of the Earth is by far the densest. It is made up of iron and nickel and has a density of around 13 g/cm3. This is almost 3 times as dense as the next layer out, the mantle.
The mantle is made up of silicates and has a density of around 4 g/cm3. The outermost layer of the Earth, the crust, is made up of silicates and has a density of around 2-3 g/cm3. So why is the innermost layer so much denser than the other layers?
There are two main reasons. First, iron and nickel are much heavier elements than silicon (which makes up most of the mantle) or oxygen (which makes up most of the crust). Second, at high temperatures and pressures, such as those found deep in the Earth, iron, and nickel atoms tend to pack together more closely than lighter atoms like silicon or oxygen.
This gives them a higher density.

-What is the Densest Layer of the Earth
The most dense layer of the Earth is the outer core. The outer core is made up of iron and nickel and is about 2,200 kilometers thick. It has a temperature of around 4,000 degrees Celsius and a pressure of 150 million times that of the atmospheric pressure at sea level.
Conclusion
The Earth is made up of three main layers: the crust, the mantle, and the core. The crust is the outermost layer and is very thin compared to the other two layers. The mantle is the middle layer and is much thicker than the crust. The core is the innermost layer and is by far the most dense of all three layers.
