In the centre of a pumice-covered plateau from loon to 2000 ft. In 1886 there was a serious volcanic eruption in the outlying island of Nivafoou, and at the same time Falcon Reef, normally awash at high water, discharged sufficient scoriae and pumice to form a new island 50 ft.
The superior facet, also called the superior articular process, is a pair of facet joints between pairs of vertebrae. A facet joint is what holds two vertebrae together and each vertebra contains two pairs, an upper-facing superior facet pair and a lower-facing inferior facet pair.
Each rib articulates with the vertebral column in three places. The head of the rib articualtes with the superior coastal facet of the vertebra after which it is number, the i â¦ nferior coastal facet of the vertebra above it and the articular facet on the transverce process of the vertebrae aftr which it is numbered.ach disc is slightly flexible, so the combined movement of many of the joints in the vertebral column allows the back to bend forward or the the side or to twist. they are amphiarthrotic joints because these joints allow slight movement.
