Calcite - Mineral, Crystals, Sedimentary Rocks: A large percentage of the calcite in rocks was deposited in sedimentary environments; consequently, calcite is a constituent of several diverse sediments, sedimentary rocks, and their metamorphosed products. A minor amount of the Earth's calcite is of magmatic (i.e., igneous) origin; it is the chief …

Coal and global warming. Of coal's many environmental impacts, none are as harmful, long term, and irreversible as global warming. Global warming is driven by emissions of heat-trapping gases, primarily from human activities, that rise into the atmosphere and act like a blanket, warming the earth's surface.

2. The many ways mining activities impact biodiversity. Mining affects biodiversity at multiple spatial scales (site, landscape, regional and global) through direct (i.e. mineral extraction) and indirect processes (via industries supporting mining operations, and external stakeholders who gain access to biodiversity-rich areas as the result of …

Unlike calcite, gypsum does not react with dilute acid to form bubbles, although if the gypsum is crushed into a powder it may simply dissolve. Quartz: Quartz crystals and masses may have the same luster as calcite, but quartz does not exhibit cleavage and will not react with dilute acid. Quartz is also much harder than calcite.
