The sphere is the simplest model of the earth which approximates the shape and size of the earth. a better approximation of the shape of the Earth is the spheroid which takes into account the fact that the earth is wider along the equator than between the poles.
Thallium is a chemical element with the symbol Tl and atomic number 81. It is a gray posttransition metal that is not found free in nature. When isolated, thallium resembles tin, but discolors when exposed to William Crookes and ClaudeAuguste Lamy discovered thallium independently in 1861, in residues of sulfuric acid production. Both used the newly developed method of flame ...
Cassiterite has "over the limit" (OTL) refractive indices of Faceted transparent cassiterites may show birefringent effects such as doubling and fuzziness. The most distinguishing property of this gemstone is its very high specific gravity (SG) range of All gems of this density or higher are rarely faceted, but ...
Larger and denser (higher specific gravity) sediments require more wind, stream, or wave energy to stay afloat. If we know the size and specific gravity of the mineral that we are looking for, and we know the energy levels of a stream (or wave), then we can predict where in the stream (or shoreline) we should look for that mineral.

Tin does not occur naturally in pure form, so it must be extracted from other ores. Because of tin dioxide's high specific gravity, tin is often mined downstream of a primary deposit – along river banks, in valleys, or at the bottom of the ocean. Therefore, the most economical extraction methods are dredging, openpit and hydraulic mining.

Palladium is also used in electronics, dentistry, medicine, hydrogen purification, chemical applications, groundwater treatment, and jewelry. Palladium is a key component of fuel cells, which react hydrogen with oxygen to produce electricity, heat, and water. Ore deposits of palladium and other PGMs are rare.
