Question 5261: Set of all grains of sand in the world.{Infinite Set/Finite Set}
Answer by xcentaur(357)   (Show Source):
You can put this solution on YOUR website! If the number of grains of sand in the world were a finite number,and did not change ever in response to anything,then this set would be a finite set.
However,old rocks are weathered to form sand all the time,forming new grains of sand.
Now,I won't pretend to be an expert on this subject.If you say that all grains of sand can be counted and assumed to be finite,then this is a finite set.Otherwise,by the argument above,this would be an infinite set.
