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.

Describe how the temperature profile of air near Earth's surface controls the type of precipitation that falls to the ground. The type of precipitation that reaches Earth's surface depends on the temperature profile in the lowest few kilometers of the atmosphere. Temperature profile is the way the air temperature changes with altitude. For example, even on a hot summer day, rainfall may have begun as a snowstorm high in the clouds overhead.
