The highest point of a transverse wave is called the CREST, while the lowest point of a traverse wave is called the TROUGH. Added 186 days ago|4/18/2015 2:58:34 PM. This answer has been confirmed as correct, not copied, and helpful. Confirmed by yumdrea [4/19/2015 4:18:08 PM].
The jointer plane (also known as the try plane or trying plane) is a type of hand plane used primarily to straighten the edges of boards in the operation known as jointing. A jointer plane may also be used to flatten the face of a board.
There, the two joint planes in the Marcellus are nearly at right angles, each making cracks in the formation that run perpendicular to the bedding plane, which lies almost level. These joints form smooth nearly vertical cliffs, and the intersecting joint planes form projecting corners in the rock faces.
