10 Interesting Facts about The Earth’s Structure

These are the following Facts about The Earth’s Structure which probably give you the important information you can find out about this. The Earth’s Structure divide into two part which are interior and exterior. The dividing parts because of the earth which is a mass square, then it has both inside and outside parts. Also the layered in spherical shells can be said as the onion. And here are the following facts about The Earth’s Structure which need to read below.

Facts about The Earth’s Structure 1 : Interior

It is the most inside layer of earth’s shells. Defined by either their chemical or the rheological materials. The interior (inner core) is the solid layer. There is seismic waves pass through the earth. It measured by the gravity field on the earth.

Facts about The Earth’s Structure 2 : Mass Calculated Resource

The earth’s mass calculated by the force exerted from the earth’s gravity. Also average density can be calculated of the mass of earth. Orbit and effects on nearby planetary bodies can set as the reference on calculating earth’s mass.

Facts about The Earth’s Structure 3 : Mechanically

It is one of two way to define the structure of the Earth. Mechanically, the earth can divided into lithosphere, asthenosphere, mesospheric mantle, outer core and inner core. Then in the interior earth can be divided into 5 important layers then.

Facts about The Earth’s Structure 4 : Chemically

It’s the other way to define the earth’s structure. Chemically, the earth’s divided into the crust, upper mantle, lower mantle, outer mantle and inner core. The chemical materials are variety based on the depth or high of parts.

Facts about The Earth’s Structure 5 : Earth’s Layer

It can be defined indirectly of the time of travel of refracted and reflected seismic waves which created by earthquakes. The speed of travel (seismic velocity) are in variety for different layers. The change of seismic velocity caused by refraction owing of Snell’s Law. Find out facts about Diamond Jubilee here.

Facts about The Earth’s Structure 6 : Core

It’s the deepest part of earth. The core divided in two parts, solid inner core with radius of -1,220 km and the liquid outer core which has radius of -3,400 km. The densities in outer core between 9,900 and 12,200 kg/m3 and the inner between 12,600 – 13,000 kg/m3

Facts about The Earth’s Structure 7 : Mantle

It has depth around 2,890 km. And it is the thickest layer of the earth. It also called as asthenosphere. It composed by silicate rocks which rich of iron and magnesium relative to the underlying crust. It a solid layer, but by the high temperature on it then it will be ductile that can flow on a very long timescales.

Facts about The Earth’s Structure 8 : Crust

It ranges between 5-70 km in depth and is the outmost layer. Divide into two crust, oceanic and continental. The oceanic is the thin crust composed by dense iron magnesium silicate igneous rocks, like basalt. The Continental is the thicker, composed by sodium potassium aluminium silicate rocks, such as granite.

Facts about The Earth’s Structure 9 : Edmund Halley Paper

On his paper (Philosophical Transactions of Royal Society of London), he put forth the idea of earth consisting of a hollow shell as 500 miles thick. Two inner concentric shells around an innermost core, which coresponding to the diameter of Venus, Mars of Mercurius respectively. Let’s check out facts about The Drums here.

Facts about The Earth’s Structure 10 : Sir Isaac Newton, in Principia

In Principia (1687), it told that Sir Isaac Newton demonstrated of the Moon which to be more solid than the Earth. Moon more solid as 9 to 5 equals. Get facts about The Drums here.
