Cracks in the rock got filled with water causing the expansion of the cracks. then rocks get broken off as it expands. The arch is formed only when all the rock is removed and stronger, harder rock is left over making the arch. Then (this will happen to the Green Bridge of Wales someday) as the arch gets bigger and biggger and bigger until the top of the arch collapses leaving something called a stack and then as the stack erodes leaving only a stump
