On Earth, liquid water removes carbon dioxide from the atmosphere and combines it with calcium, from rock weathering, to form carbonate sedimentary rocks. Without liquid water to remove carbon from the atmosphere, the level of carbon dioxide in the atmosphere of Venus remains high. [#paragraph3]...
If it is not a theory, what is it? When a person says, “My hypothesis is that excess calcium in the diet causes kidney stones,” what does the person need to do to determine if the hypothesis is correct? Some people argue that many scientists accept many scientific principles on faith...
Petrocalcic — in which so much calcium carbonate is accumulated that it literally forms a rock-like layer in the middle of a soil (Figure 8c). Soil scientists capture this vast diversity through systems of soil classification. The U.S. system, called Soil Taxonomy (soils.usda.gov/technical...

There is no 100% clean substance in nature! Stone may contain protein (mucoprotein), and those stones are usually very hard. Only protein stones and stones containing a lot of calcium carbonate are hard stones. Be aware that hard stones are rather rare. ...
Although coral reefs may seem like the natural source for such a supplement, coral calcium is most often obtained by processing limestone. Reefs are protected from exploitation or harm all around the world, and it is very difficult to harvest dead coral without damaging the living reef. Additiona...
