Transcript of Recommended rocks to use in a statue.

By: Ryan Lally Recommended Rocks to use in a Statue Statues can be made out of anything. Some people make statues out of ice. Some people make statues out of duct tape. But for a statue to last, it must be made out of something much sturdier. Natural rocks and minerals that are found in the Cincinnati area could be used as a statue at the Great American Ballpark. You will learn about which rocks are good choices for building statues. Introduction Granite Sandstone - igneous rock that is composed primarily of four minerals - quartz, feldspar, mica, and usually hornblende - Hardness = 6 or 7 - change relatively little with changes in temperature Cost Availability In my opinion, the best rock to use to make a statue at the Great American Ball Park in Cincinnati would be granite. It is not that expensive, is easily found in Cincinnati, and would last for a long time. Granite is an igneous rock that holds up in all types of weather and is strong. Plus it would make a great looking statue! Conclusion - the ability to resist bending force - sedimentary rock made of sand, rich in quartz and other minerals, being compacted over a long period of time - combined with calcium carbonate, silica, and iron oxide - hardness: varies depending on the rock - weathering and erosion over time may break down the statue Marble - metamorphic rock that is composed of calcite, aragonite and dolomite crystals -rating of between 4 and 5 on the Mohs scale of hardness for rocks and minerals - has a relatively high mass, and therefore is slow to change temperature - very durable and long lasting for statues Granite - $4.00 per sq.ft. Sandstone - $3.00 - $5.00 per sq.ft. Marble - $8.87 per sq.ft. Ohio has all three types of rocks: igneous, sedimentary, and metamorphic. Sedimentary is the most common. It is found at the top layer of land all throughout Ohio. Sandstone is a type of sedimentary rock. Ohio is ranked 3rd nationally in the production of sandstone. Igneous (granite) and metamorphic (marble) rock are found deeper in the earth but are also easily found in Ohio. The glaciers from the Ice Age carried the rocks to Ohio.
