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.
A syncline is the opposite of an anticline. It is a downward fold or dip in underground strata. The anticline is the upward fold in a layer of strata. If you can picture a layer of subterranean strata that goes across in a straight or flat line, then comes to a plunging U-shaped dip, then you've got the syncline pictured. The opposite for the anticline. Sometimes we see the two together, as in side by side.
