My best likely guess
Answer:
Transport of sediments causes them to become rounder as their irregular edges are removed both by abrasion and corrosion. Beach sand becomes highly rounded due to its endless rolling and bouncing in the surf.

a tundra us a freezing place so hardly any plant life can grow, and it's always cold.
The waves crash into the sand, sometimes creating dunes, and it can also wash some sand out into the ocean. Hope this helps!
