Each star displays a number. The youth or adult member combines stars to show his or her years of service. For example, a boy who was a Cub Scout for four years and a Boy Scout for six years would wear a four-year service star on a gold backing and a six-year service star on a green backing.

A synclinorium is a large syncline with superimposed smaller folds. Synclines are typically a downward fold, termed a synformal syncline; but synclines that point upwards, or perched, can be found when strata have been overturned and folded.
Definition of Midline. The midline is a horizontal axis that is used as the reference line about which the graph of a periodic function oscillates. The equation of the midline of periodic function is the average of the maximum and minimum values of the function. Figure-1 shows y = sin x and Figure-2 shows y = sin x + 1. The second curve is the first curve shifted vertically up by one unit.
