## Which is denser the inner or outer core?

The outer core is made up of slightly less dense material compared with the inner core, the lower mantle is less dense than the outer core, the upper mantle is less dense than the lower mantle, and so on with the crust being the least dense and lightest portion of our Earth.

What is the density of each layer of the Earth?

Structure of the Earth

Thickness (km) Density (g/cm3)
Crust 30 2.2
Upper mantle 720 3.4
Lower mantle 2,171 4.4
Outer core 2,259 9.9

### Which part of the Earth has highest density?

metal inner core
Earth’s interior layers are ordered by density. The densest layer is the solid metal inner core, the mantle is of intermediate density, and the least dense layer is the lithosphere, particularly the continental lithosphere.

Is the Earth’s density the same as the core?

The density of Earth’s crust is a little less than the Moon’s, but Earth’s density increases toward the core. Earth has five layers: the inner core, the outer core, the mantle, the asthenosphere, and the crust (Figure 1). Because each layer has a different composition, they also each have a different density.

## What is the second most dense layer of the Earth?

What is the second most dense layer of earth?

Thickness (km) Density (g/cm3)
Crust 30 2.2
Upper mantle 720 3.4
Lower mantle 2 171 4.4
Outer core 2 259 9.9

What is density of inner core?

The inner core has a radius of 1 216 km and the total radius of the core is 3486 km. The core is composed mostly of iron (80%) and some nickel. The density of the inner ‘solid’ core is between 9.9-12.2 g/cm3 and the outer core’s density is between 12.6-13 g/cm3.

### Which layer of the Earth is the least dense?

the crust
In relation to the other layers the crust is the thinnest and the least dense layer. It floats on the softer, denser mantle.

Which layer of the Earth has highest density and why?

The correct option is (A) Inner core. That is, the inner core is the layer of the earth that is believed to have the heaviest mineral materials of the highest density.

## What are the differences between the inner and outer core?

The inner core and the outer core are made up of similar stuff chemically (both are made mostly of iron, with a little nickel and some other chemical elements)–the difference between them is that the outer core is liquid and the inner core is solid.

Which Earth’s crust is most dense?

Even though it is relatively thin it is Continent Tit UE Oceanic Crus! Magma Page 2 the densest type of crust (3.0 g/cm) and is made up of a metamorphic rock called basalt. Continental crust makes up the continents and rests on top of oceanic crust. Continental crust consists of less dense rock such as granite.

### Which atmosphere layer is the most dense?

The troposphere is the densest atmospheric layer, compressed by the weight of the rest of the atmosphere above it.
