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.

Best Answer: The troposphere begins at the Earth's surface and extends up to 4-12 miles high. As the gases in this layer decrease with height, the air become thinner.Therefore, the temperature in the troposphere also decreases with height. As you climb higher, the temperature drops from about 62Â°F to -60Â°F. http://www.srh.noaa.gov/srh/jetstream/at...Source(s):Strm Chsr07 Â· 8 years ago.s the gases in this layer decrease with height, the air become thinner.
