I like the style promoted by The Gregg Reference Manual because it is simple and straightforward. Regarding hyphenated words, Gregg says, In a heading or title, capitalize all the elements except articles, short prepositions, and short conjunctions.. In Gregg, short means fewer than four letters. Following the Gregg way, both parts of Tune-Up are capitalized because up is an adverb in that expression.
A geodesic dome is a sphere-like structure composed of a complex network of triangles. The triangles create a self-bracing framework that gives structural strength while using a minimum of material.
Geodes (Greek Î³ÎµÏÎ´Î·Ï - ge-ÅdÄs, earthlike) are commonly independent spherical masses of resistant mineral matter that are usually hollow. The extreme filling of a geode so that it is solid is also common.Some people refer to completely in-filled geodes as nodules, but the two names are not always consistently used.eodes differ from nodules in that a nodule is a solid mass of mineral matter, but some nodules may have a tiny void space in their interiors and the distinction between a geode and a nodule may be barely discernible if the cavity is miniscule.
