The
verse 11 of Sura Tarik in the Qur'an, refers to the "returning"
function of the sky.
"By Heaven with
its cyclical systems."
(The Qur'an, 86:11)
(The Qur'an, 86:11)
This word interpreted as "cyclical"
in Qur'an translations also has meanings of "sending back"
or "returning".
As known, the atmosphere surrounding
the Earth consists of many layers. Each layer serves an important
purpose for the benefit of life. Research has revealed that these
layers have the function of turning the materials or rays they
are exposed to back into space or back down to the Earth. Now
let us examine with a few examples of this "recycling"
function of the layers encircling the Earth.
The troposphere, 13 to 15 kilometers
above the Earth, enables water vapor rising from the surface of
the Earth to be condensed and turn back as rain.
The ozone layer, at an altitude
of 25 kilometers, reflects harmful radiation and ultraviolet light
coming from space and turns both back into space.
The ionosphere, reflects
radio waves broadcast from the Earth back down to different
parts of the world, just like a passive communications satellite,
and thus makes wireless communication, radio, and television broadcasting
possible over long distances.
The magnetosphere layer turns
the harmful radioactive particles emitted by the Sun and other
stars back into space before they reach the Earth.
The fact that this property of
the atmosphere's layers, that was only demonstrated in the recent
past was announced centuries ago in the Qur'an, once again demonstrates
that the Qur'an is the word of God.
The presence of water is essential for life on Earth. One of
the factors acting in the formation of water is the Troposphere, one of the
layers of the atmosphere. The troposphere layer enables water vapour rising
from the surface of the Earth to be condensed and turn back down to the Earth
as rain.
The atmosphere
layer that blocks the rays that might be fatal to life on
Earth is the Ozonosphere. The Ozonosphere turns harmful
cosmic rays like ultraviolet back to space, hence preventing
them from reaching the Earth and harming life.
Each layer
of the atmosphere has beneficial attributes for human beings.
The Ionosphere layer, one of the upper layers of the atmosphere,
for example, reflects radio waves broadcast from a certain
centre back down to the Earth, thus enabling broadcasts
to be received from long distances.
