The seven layers of the earth
which scientists have recently
discovered was eluded by
Prophet Muhammad 1400 years ago
Sunnah of the Prophet Muhammad is the second revealed source of Islam . As the Qur’an , containing scientific information available 1400 years ago. These miracles are ” seven” lands mentioned by the Prophet in several of his speeches . They are:
It was narrated on the authority of Abu Salamah that a dispute arose between him and other people ( on the ground) . ! When he told Aisha ( the Prophet’s wife ) about it , he said, ” O Abu Salamah Avoid taking the land unjustly , for the Prophet said :
“Whoever usurps even a span of land of somebody, its depth through the seven earths will be collared to his neck . ” ( Sahih al- Bukhari , “Book of oppression.”)
Salim reported on the authority of his father that the Prophet said :
“Whoever takes a piece of land of others unjustly , he will sink to the bottom of the seven earths on the Day of Resurrection.” ( Sahih al- Bukhari , “Book of oppression. ” )
The aforementioned Hadith prohibits oppression in general, particularly the taking of a parcel of land belonging to others unjustly. What could be the reference of seven lands ?
Geology studies have shown that the earth consists of seven areas identified from the inside to the outer layers as follows :
( 1) The interior of the Earth solid core : 1.7 % by mass , the depth of 5150-6370 km from Earth ( 3219-3981000 )
The inner core is solid and attached to the garment suspended in the molten outer core. It is believed that solidified as a result of the pressure of the freezing occurs most liquids decreases when the temperature or pressure increases .
( 2) The liquid outer core : 30.8 % of the mass of the Earth , the depth of 2890-5150 km ( 1806-3219000 )
The outer core is heated electrically conductive liquid in which the convection. This conductive layer combines with Earth ‘s rotation to create a dynamo effect of a system of electrical currents known as the Earth ‘s magnetic field . It is also responsible for the subtle shake of the rotation of the Earth. This coating is not as dense as molten pure iron , indicating the presence of the lighter elements . Scientists suspect that about 10 % of the layer is composed of sulfur and / or oxygen because these elements are abundant in the cosmos and dissolve readily in molten iron .
( 3) The ” D ” layer : 3% of the mass of the Earth , the depth of 2700-2890 km ( 1688-1806000 )
This layer is 200-300 kilometers ( 125-188 miles) thick and represents about 4 % of the mass of the mantle – crust. Although it is often identified as part of the lower mantle , seismic discontinuities suggest the ” D” layer might differ chemically coat that lies beneath. Scientists suspect that the material is dissolved in the core, or may be filtered through the layer , but not in the nucleus due to its density .
(4 ) Lower Mantle : 49.2 % of the mass of the Earth, the depth of 650-2890 km ( 406 miles 1806 )
The lower layer contains 72.9 % of the mass of the layer and is probably mainly composed of silicon, magnesium and oxygen . You probably also contains some iron , calcium and aluminum . Scientists make these deductions by assuming the Earth has a large number and proportion of cosmic elements as found in the Sun and primitive meteorites .
(5) Middle Mantle ( Transition region ) : 7.5 % by mass , the depth of 400-650 kilometers ( 250-406 miles ) from Earth
The transition region or mesosphere ( for middle mantle ) , sometimes called the fertile layer , contains 11.1% of the mass of the mantle and is the source of basaltic magmas. It also contains calcium , aluminum and garnet , a complex bearing aluminum silicate mineral . This layer is dense cold due to garnet. Take hot because these minerals melt easily to form basalt which can then rise through the upper layers of magma. seven
(6 ) the upper mantle : 10.3% of the mass of the Earth , the depth of 10-400 km ( 6-250 miles)
The upper mantle contains 15.3% of the mass of the mantle. The fragments were extracted by eroded mountain belts and volcanic eruptions. Olivine (Mg , Fe) 2SiO4 and pyroxene (Mg , Fe) SiO 3 were the main minerals found in this way. These and other minerals are refractory and crystalline at high temperatures , therefore , most settle out of rising magma is, is the training of new material or never leaving the mantle. A portion of the upper mantle called the asthenosphere is partially molten . seven
( 7) the lithosphere
Oceanic crust : 0.099 % of the mass of the Earth, the depth of 0-10 kilometers ( 0-6 miles )
The rigid, outermost layer of the Earth comprising the crust and upper mantle is called the lithosphere. The oceanic crust contains 0.147 % of the mass of the mantle – crust. Most of the earth’s crust is made through volcanic activity. The oceanic ridge system , a network of 40,000 km (25,000 miles) from volcanoes, generates new oceanic crust at the rate of 17 km3 per year, covering the bottom of the ocean basalt . Hawaii and Iceland are two examples of cell accumulation basalt . seven
The continental crust contains 0.554 % of the mass of the mantle – crust. This is the outermost part of the earth is composed essentially of crystalline rocks. These are the low density mineral transport dominated mostly by quartz ( SiO2) and feldspars (metal-poor silicates) . The crust ( both oceanic and continental ) is the surface of the Earth , as such , is the coldest part of our planet. Due to the cold rocks deform slowly, we refer to the rigid lithosphere (rocky or strong layer ) outer shell. seven
The layers of earth shall match the above mentioned hadith of the Prophet . The miracle is on two questions:
(1) The term of the hadith : “It will sink to the bottom of the seven earths on the Day of Resurrection ,” the stratification of these “lands ” around the ball.
(2) The accuracy with which the Prophet of Islam spoke seven inner layers of the Earth.
