Expert Answer:

  • Due to constant flow of water, the parent rock is weathered thereby causing change in shape and size of the rock.
  • The parent rocks gets cracked, crumbled and crushed, producing a range of materials with different sizes, from large boulders to fine particles.  
  • For example - large boulders get broken down into smaller fragments as they carried along with the mountain streams and rivers.
  • Rocks at sea shores also get weathered due to waves.
