the mountains must have a lower density because of their greater length than the shorter rock columns
beneath the plains. Both Airy and Pratt's hypothesis imply that surface irregularities are balanced by
differences in density of rocks below the major features (mountains and plains) of the crust. This state
of balance is described as the concept of isostasy.[26]
Today, we know that the rocky external layer of the Earth's surface is riven by deep faults and split
into plates swimming above the molten lava. Since the Earth revolves very quickly around its own
axis, were it not for the fixing effect of the mountains, these plaques would shift. In such an event,
soil would not collect on the Earth's surface, water would not accumulate in the soil, no plants could
grow, and no roads or houses could be built. In short, life on Earth would be impossible. Through the
mercy of Allah, however, mountains act like nails, and to a large extent, prevent movement in the
Earth's surface. This vital role of the mountains, which has been discovered by modern geological and
seismic research, was revealed in the Qur'an centuries ago as an example of the supreme wisdom in
Allah's creation: "… [He] cast firmly embedded mountains on the earth so that it would not
move under you…" (Qur'an, 31/10)
Modern Science has discovered that in the places where two different seas meet, there is a barrier
between them. This barrier divides the two seas so that each sea has its own temperature, salinity
and density.[27]For example, the Mediterranean Sea water is warm, saline and less dense, compared
to the Atlantic Ocean water. When the Mediterranean Sea water enters the Atlantic Sea over the
Gibraltar sill, it moves several hundred kilometers into the Atlantic at a depth of about 1000 meters
with its own warm, saline and less dense characteristics. The Mediterranean Sea water stabilizes at
this depth.[28]
Although there are large waves, strong currents and tides in these seas, they do not mix or transgress
this barrier. The Qur'an mentions that there is a barrier between two seas that meet and that they do
not transgress. The Qur'an (55/19-20) says, "He has set free the two seas meeting together.
There is a barrier between them. They do not transgress." But when the Qur'an speaks about
the divider between fresh and salt water, it mentions the existence of "a forbidding partition" with the
barrier. The Qur'an (25/53) says, "He is the one who has set free the two kinds of water, one
sweet and palatable, and the other salty and bitter. And He has made between them a
barrier and a forbidding partition."
One may ask, why does the Qur'an mention the partition when speaking about the divider between
fresh and salt water but does not mention it when speaking about the divider between the two seas?
Modern science has discovered that in estuaries, where fresh (sweet) and salt water meet, the
situation is somewhat different from what is found in places where two seas meet. It has been
