RAINS THAT GIVE LIFE TO A DEAD LAND
                   In the Qur’an, many verses call our attention the rain’s function of "bring-
               ing a dead land to life". "…And We send down from heaven pure water so
               that by it We can bring a dead land to life and give drink to many of the
               animals and people We created." (Surat al – Furqan: 48-49)
                   In addition to furnishing the earth with water, which is an inevitable need
               of living beings, rain also has a fertilising effect.
                   Raindrops that reach the clouds after being evaporated from the seas con-
               tain certain substances "that will give life" to a dead land. These "life-giving"
               drops are called "surface tension drops". Surface tension drops form on the top
               level of the sea’s surface, which is called the micro layer by biologists. In this
               layer, which is thinner than one tenth of a millimetre, there are many organic
               leftovers from the pollution caused by microscopic algae and zooplankton.
               Some of these leftovers select and collect within themselves some elements
               which are very rare in sea water, such as phosphorus, magnesium, potassium
               and some heavy metals like copper, zinc, cobalt and lead. These "fertiliser"-
               laden drops are lifted up into the sky by the winds and after a while they drop
               on the ground inside the raindrops. Seeds and plants on
               the earth find numerous metallic salts and elements
               essential for their growth here in these raindrops. This     It is He Who made the
               event is revealed in another verse:                          earth a cradle for you
                   "And We sent down blessed water from the sky            and threaded pathways
                   and made gardens grow by it and grain for har-           for you through it and
                   vesting." (Surah Qaf: 9)                                 sent down water from
                   The salts that fall in rain are small examples of cer-   the sky by which We
               tain conventional fertilisers (calcium, magnesium, potas-     have brought forth
               sium, etc.) used for increasing fertility. The heavy metals    various different
               found in these types of aerosols, on the other hand, are        types of plants.
               other elements that increase fertility in the development     (Surah Ta Ha: 53)
               and production of plants.
                   Briefly, rain is an important fertiliser. A barren land
               can be furnished with all the essential elements for
               plants, over a hundred-year period, just by these fertilisers dropped with rain.
               Forests also develop and are fed with the help of these sea-based aerosols.
                   In this way, 150 million tons of fertiliser falls on the total land surface every
               year. If there were no natural fertilisation like this, there would be very little
               vegetation on the earth, and the ecological balance would be impaired.
