Why does it take less time for small rocks to wear away than it does for large rocks to wear away?

If you take one large rock it only wears away on its surface.
If you now break that rock in half the surface is the old outside AND the new break in half - therefore more surface area to wear away. Break these two halves again and there is more surface area to wear away.
Keep going and break your large rock into many pieces and you get small rocks which wear away much quicker.

It is because that small rocks are lighter than large rocks. It is hard for larger rocks because they are very heavy.

Small rocks wear away faster than large rocks because they have a greater surface area exposed to weathering, allowing for more efficient breakdown. When large rocks are broken into smaller pieces, the increased surface area accelerates the weathering process. Environmental factors also play a role, as smaller rocks are often more susceptible to changes and movement in nature.
