Solution

The grain that has traveled the farthest in a marine sediment is typically the small round grain. Here's why:

  1. Grain Size: Smaller grains are lighter and can be transported further by water currents compared to larger grains.

  2. Grain Shape: Round grains have a smoother surface which reduces friction, allowing them to be transported further compared to grains with pointy edges or flat grains.

  3. Erosion: The process of erosion tends to make grains smaller and rounder over time. So, a small round grain has likely been subjected to more erosion, indicating that it has traveled a longer distance.

So, the small round grain is the one that indicates it has traveled the farthest in a marine sediment.
