Rock weathers away

Calcium enters the biosphere as dust; since it has no gas state, it does not remain in the atmosphere. As the form of dust, Calcium is moved by air and water throughout the biosphere.

The biosphere is the global sum of all ecosystems. It can also be called the zone of life on Earth, a closed (apart from solar and cosmic radiation and heat from the interior of the Earth), and self-regulating system.

Calcium carbonate or silicates

Sulfur Cycle:
Sulfur from the bodies of water and land rise up to sky in the form of Hydrogen Sulfide Gas, and later condenses in the sky and comes back down as precipitation

Too much calcium in the blood can result in impairment of the kidney, increasing the absorption of iron, zinc, magnesium, and phosphate.

sea spray, marshes, tidal flats, volcanic activity

As a soil amendment, calcium helps to maintain chemical balance in the soil, reduces soil salinity, and improves water penetration.
