Calcium content: Calcium carbonate is the most prevalent calcium supplement in the market. It provides more elemental calcium than calcium citrate, so you may not need to take as many pills. As in the example explained in the elemental calcium section, a 500 mg calcium carbonate provides 200 mg elemental calcium.
In the Earth's atmosphere, temperature varies greatly at different heights relative to the Earth 's surface. The coldest temperatures lie near the mesopause, an area approximately 85 km (53 mi) to 100 km (62 mi) above the surface.n the Earth's atmosphere, temperature varies greatly at different heights relative to the Earth 's surface. The coldest temperatures lie near the mesopause, an area approximately 85 km (53 mi) to 100 km (62 mi) above the surface.
In the troposphere, temperatures decrease as the altitude increases as it loses heat emitted from the surface of the Earth. In the stratosphere, the temperature increases with increasing altitude as the amount of ozone-absorbing ultraviolet rays increases. In the mesosphere, temperatures decrease as altitude increases and can reach -194 degrees Fahrenheit. By contrast, temperatures in the thermosphere can reach over 2,700 degrees Fahrenheit.Learn more about Atmosphere.
