Precious metals are any one of a number of relatively uncommon and valuable metals. They are used in jewelry, in coins and sometimes as specie or monetary metals. The three primary precious metals: silver, gold at platinum. Another very valuable metal is palladium. Silver: Chemical...

To be considered a precious metal, a metal must be rare, occur naturally, and be chemically and radioactively stable. This combination of traits gives the precious metal its financial value. Unlike modern floating currencies, which only have fiat value, a precious metal is considered a...

Sedimentary rocks refer to rocks that are formed through the deposition of sediments known as the process of sedimentation. Natural phenomenon like weathering and erosion also contributes to the formation of sedimentary rocks. Thus, scientists and researchers often used sedimentary rocks to figure out how...
The classification of sedimentary rocks
By: John Welford
There are basically two ways of classifying sedimentary rocks, either by how they originated or their composition. The latter takes into account such matters as whether they contain primarily coarse-textured sands or fine clays, or whether they have a high carbon content due to being...

Sedimentary rocks are one of the three types of rocks that form the earth's surface. The other two are igneous and metamorphic rocks. Sedimentary rocks are formed by the accumulation of small rocks particles in the earth surface through erosion, weathering, transportation of the sediments...

Igneous rocks are solid forms of magma that has been extruded by volcanic processes. The word “igneous” derives from “ignis,” the Latin for “fire.” Magma is molten rock that rises from deep within the earth’s crust and which cools...
The classification of sedimentary rocks
By: Effie Moore Salem
Sedimentary rocks, or rocks formed from sediment, dust, garden soil, particulates from the air, substances from lakes, rivers, creeks, and ponds that have become stationary, are of three basic divisions: siliciclastic - or clastic - chemical and biochemical. And these, for added simplicity in identification...
The classification of sedimentary rocks
By: Paul Manalo
Sedimentary rocks are often found around bodies of water or aqueous environments. This is because water is an important element in the formation of sedimentary rocks. An example of how a sedimentary rock forms is through erosion of a rock due to the forces of...
