What reading level is The Story of a Piece of Coal What It is Whence It Comes And Whither It Goes book?
To quickly assess the difficulty of the text, read a short excerpt:
This will be more clearly un- derstood when it is explained that, by its action, a seam of coal, which is subject to numerous faults, can never be pierced more than once by one and the same boring. In mountainous dis- tricts, however, there are occasions when the hade is to the up-throw, and this kind of fault is known as an inverted fault.
Lines of faults extend sometimes for hundreds of miles. The great Pennine Fault of England is 130 miles long, and others extend for much greater distances. ...The surfaces on both sides of a fault are often smooth and highly polished by the movement which has taken place in the strata. They then show the phenomenon known as slicken-sides. Many faults have become filled with crystalline minerals in the form of veins of ore, deposited by infiltrating waters percolating through the natural fissures.
In considering the formation and structure of the better-known coal-bearing beds of the car- boniferous age, we must not lose sight of the fact that important beds of coal also occur in strata of much more recent date.
