History of Earth ( Seven layers of Earth )

History of earth ( seven layers )

Seven Layers of the Earth:

It is stated in the Quran that :
"ALLAH is the who created the seven skies (higher levels) and of the earth (seven lower levels) similar to those (of the skies)" (ch.65, v.12)
In this connection it is worth nothing that the body of our planet consists of a number of concentric shells of different materials arranged in order of increasing density with depth. There are similar concentric shells in the atmosphere above the surface of the earth but associated with the earth. The troposphere, which contains oxygen in a proportion suitable to sustain life on earth and clouds, which gives rain to the earth for the provision of food, is in direct contact with the crust on which we live and from which we derive direct benefits. If troposphere and the crust, with which we are in direct contact are clubbed as one single layer, then we have the following seven concentric layers which may be the seven layers referred to in the verse cited above.
7. Exosphere                              Higher than 500 Km.
6. Thermosphere                        500 Km to 85 Km.
5. Mesosphere                             58 Km to 50 Km.
4. Stratosphere                            50 Km to 17 Km
3. Troposphere-Crust                  17 Km to sea level about 40 Km deep
2. Mantle                                     about 3000 Km deep
1. Core                                        about 3400 Km deep

Gravitation : 

The atmosphere, the clouds and all that is there on the surface of the earth, travel with it in space and are held together by the force of gravitation which is also confirmed by Quran in the following terms 
"Did We not make the earth, one that draws together to itself the living and the dead?" (ch.77 v.25-

Article on Earth's History

The history of the earth starts from about 4.5 to 5 billion years back, when it achieved a separate existence through accretion of solid material. Following information from the Quran appears to through some light on the origin of the earth.

"...and we sent down the iron in which is severe strength and other benefits for mankind." (Surah AL-KHADEED. 25)

Iron is said to have been sent down, which means that it came from regions beyond the earth. In this connection and following information taken from New Scientist Jan 13th 1990 and journal of Chemical Education, Sept 1990 deserves to be compared with the text of the above information taken from the Quran, revealed 1400 years back.

'The ultimate stellar ash is made up of iron. In iron, atomic nuclei are packed as tightly as possible. Iron is the heaviest element that gets made in a star by standard nuclear burning, It has the most stable nucleus. The energy required to synthesize iron is not available on eart. Therefore the iron found in the earth must have been synthesized in outer space'.



Information from Quran as well as Science indicates that the iron present in the earth, a major portion of which forms the core, was sent down from the outer space and that the origin of the earth was associated with a star, the sun. The Chief constituents of the globe separated into a solid core and a silicate mantle, probably when the earth was still in a molten condition due to initial high temperature. Later differentiation produced the complex outer crust on which we live
