These peaks have been raised to their present position without disturbing the horizontality of the limestones and sandstones.
The leaves always rise up on each side from beneath, and form a flattened group, more or less distinctly in proportion to the horizontality of the bough, and the contiguity of foliage below and above.

The same horizontality is observed on the headland west of it, and upon all the points and headlands to Misery and Firesteel Rivers and the mouth of the Ontonagon.
But it is only in exceptional cases that this line is not horizontal; its horizontality constitutes the norm, in our hybrid races.
Hence in normal cases its horizontality is an index of the orientation of the head.
To introduce any violent convulsion for their removal was inconsistent with the uninterrupted horizontality of the roads, and with the undisturbed aspect of those parts of the glens where the shelves come suddenly to an end.
The freshwater strata may sometimes be seen to retain their horizontality within a very slight distance of the border-rocks, while in some places they are inclined, and in few instances vertical.
Sometimes unequal movements of upheaval or depression entirely destroy that horizontality of the base-line which constitutes the chief peculiarity of an ancient sea-cliff.

The fresh-water strata may sometimes be seen to retain their horizontality within a very slight distance of the border-rocks, while in some places they are inclined, and in few instances vertical.
The succession of strata here alluded to would be consistent with the occurrence of gradual downward and upward movements of the land and bed of the sea without any disturbance of the horizontality of the several formations.
Now, the remarks already made in Chapter 2 on the original horizontality of strata are strictly applicable to mechanical deposits, and only partially to those of a mixed nature.
This horizontality is a nearly constant feature of these submarine beds, as they overlie the basaltic rocks of the plains; and it is a feature we should expect to find where there has been emergence rather than upheaval.
Whether the horizontality of the shelves or terrace-lines is really as perfect as has been generally assumed is a point which will require to be tested by a more accurate trigonometrical survey than has yet been made.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "horizontality" in a variety of sentences. We hope that you will now be able to make sentences using this word.
