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.

Above 120 miles (200 km) above sea level, temperatures in the thermosphere can vary between 600Â° and 2000Â°C (1100 and 3600Â°F). The actual temperature range is highly depe â¦ ndent on solar activity. A longer answer The thermosphere is a layer of Earth's atmosphere above the mesosphere.The thermosphere extends from 50 to 55 miles (80-90 km) above sea level, with the upper limit undefined.The temperature in the thermosphere initially rises rapidly with heights up to about 120 miles (200 km) and thereafter increases more slowly.ut this part of the atmosphere is still so thin than an object placed there would encounter very few of the high-energy (high temperature) molecules. Despite the air molecules present, the thermosphere is essentially a vacuum.
