After a rock is rounded, then also
weathering is going to affect it. Although the rocks with rough angles get
weathered more quickly, but still a rounded rock will ultimately start weathering
and becoming smaller in size. Weathering can not only alter the rock
physically, but it can also alter the rounded rock chemically depending on the
material by which it is made of. Biological weathering can always weather away
a rock without depending on its shape or size. There are other forms of
weathering also that can impact the rounded rock.
