Undoubtedly there are many ayah (signs) of science about 1000 ayah in the Holy Qur'an. One of them Spreading of the earth. Now a days it is a important news to hole world. After long time the many scientists proved that the earth expends slowly day by day. But the Holy Qur'an has declared long ago about 2500 years ago about it.

Almighty Allah says in sura no: 2, ayat no:22 “It is He, Who spread out the earth and made in it mountains standing firm and flowing rivers; and of all fruits He placed there in two spouses, He covers the night with the day. Behold, verily in these things these are Signs for those who consider”

In the past 45 years, there has been a revolution in the earth science, which has brought new understanding of our planet. This revelation has resulted in growing understanding of the force which shape the continents. Our planet’s surface  is broken into a number of cold, rigid, 100 km thick lithosperic plates. They float on a relative plastic, partially molten region called aesthenosphere. The plates move slowly, at 5 to 10 cm per year, apparently driven by thermal convective motion of the rocks in the mantle, by gravity and by rotation of the earth. Geologist are of the opinion that quantities of fresh rocks are slowly emerging from the mantle along the length of the ocean ridge and are spreading out laterally forming new crusts that advance toward continents. This phenomenon, know as the “see floor spreading” causes the drift of the plates and ultimately the spread of the earth in various ways.
