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.

Making the world better, one answer at a time. The temperature changes within the stratosphere with increasing distance from the earth. The temperature increases with altitude, reaching a maximum of about 2 degrees Celsius This is unlike the troposphere, where the temperature decreases with increasing altitude.n the stratosphere, the temperature increas â¦ es with height due to absorption of radiation by ozone. Temperature changes when altitude is in the stratosphere because of  one things. It already rises when you climb up in the stratosphere.
