Answer:
Lower
Explanation:
A pressure surface is an atmospheric surface where everywhere along that surface the pressure is equal. The surface pressure over that area is directly proportional to the air mass
Change in air pressure at a given locality often indicates a change.
Increases in air pressure do not apply exclusively to altitude. At the surface of Earth, small but significant pressure fluctuations are related to the strength of the insolation.
CO2 is an important trace gas in Earth's atmosphere. It is an integral part of the carbon cycle, a biogeochemical cycle in which carbon is exchanged between the Earth's oceans, soil, rocks and the biosphere. Plants and other photoautotrophs use solar energy to produce carbohydrate from atmospheric carbon dioxide and water by photosynthesis. Almost all other organisms depend on carbohydrate derived from photosynthesis as their primary source of energy and carbon compounds.
