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 are rocks that are plain on the outside but can have beautiful crystals on the inside. In the Greek language, geode means âshape of the earthâ, and geodes are round like earth or oblong like an egg. They can be a couple inches or several feet in size. Geodes are created in the hollow areas of soil such as animal burrows or tree roots. They are also formed in the bubbles in volcanic rock.
