A study of the various views and concepts presented by Alberuni in physical geography, shows that although he sometimes succumbs to popular thinking, he usually endeavoured to adopt a scientific approach. There are instances where he refuses to accept facts which had been established scientifically. For instance, it was proved by one of his contemporaries that the heavens do not move but it is the earth which moves on its axis in its diurnal motion. Yet Alberuni shrewdly dispenses with this idea saying that it does not effect the fundamentals of astronomy whether you assign this motion to the earth or to the heaven. This may be due to his wariness in accepting any new idea unless it was conclusively proved. It may be noted that while in cosmology his views are generally borrowed, it is in geomorphology and oceanography that he makes a mark for himself.
