boulder vs. cobble 00:00 Jun 17, 2011
On an online geological dictionary, which I will cite later, I see that a "boulder" has a diameter of more than 256 mm or 10 inches, about the size of a volleyball. A "cobble" on the other hand, has a smaller diameter, of between 64 and 356 mm. So, as Charles correctly pointed out, a "cobble" is smaller than a "boulder" according to sedimentologists.
Now I am going to attempt to find the size of the diameter of a "boleo" so we can see which term accurately translate the meaning into English. |
