Monday, October 26th 2015. | Science

Let’s find out Structure of The Earth Facts in the below explanation. If you check the modern of earth structure, it reminds you with an onion. It has several layers. The rheological or chemical properties define each layer of earth. Get more facts about the earth’s structure below:

## Structure of The Earth Facts 1: the structures of earth

The structure of earth contains the solid inner core, a liquid outer core, a viscous mantle and an outer silicate solid crust.

### Structure of The Earth Facts 2: the internal structure of earth

The scientists find out the internal structure of earth by making some observations on the bathymetry and topography of earth. They also measure the magnetic field and gravitational fields of earth. The analysis of seismic is also conducted to support the observation.

## Structure of The Earth Facts 3: the mass

Do you know how to calculate the mass of earth? The scientists often conduct the observation on the force produced by the gravity of earth.

### Structure of The Earth Facts 4: the average density

The average density of earth can be calculated by checking the volume of the planet.

## Structure of The Earth Facts 5: the astronomers

The mass of earth can be calculated by the astronomers when they check the orbit and effect of the planetary bodies located nearby earth.

### Structure of The Earth Facts 6: the interior of earth

Let’s find out the interior of earth. It begins with the continental crust. Then it is followed by oceanic crust. Then you can find upper mantle, lower mantle, outer core and inner core.

## Structure of The Earth Facts 7: the ways to define the earth’s structure

There are two ways to define the structure of earth. You can define it mechanically or even chemically. Check facts about sedimentary rocks here.

### Structure of The Earth Facts 8: the mechanical definition

If you define the structure of earth mechanically, it is divided into the inner core, outer core, mesospheric mantle, asthenosphere and lithosphere.

## Structure of The Earth Facts 9: the chemical definition

The structure of earth based on the chemical definition is seen in five layers. Those are the inner core, outer core, lower mantle, upper mantle and crust. Get facts about sinkhole here.

### Structure of The Earth Facts 10: the inner core

Inge Lehmann discovered the inner core of earth in 1936. The scientists believed that iron and nickel were the main components in the inner core. The core of earth features the denser materials. The liquid outer core is located beyond the radius of ~3,400 km, while the solid inner core is seen in the radius ~1,220 km.
