2 days ago · In Earth's atmosphere, carbon dioxide is a trace gas that plays an integral part in the greenhouse effect, carbon cycle, photosynthesis and oceanic carbon cycle. It is one of several greenhouse gases in the atmosphere of Earth. The current global average concentration of carbon dioxide (CO 2) in the atmosphere is 421 ppm (0.04%) as of May 2022.
Jul 1, 2024 · Climate - Biosphere, Atmosphere, Structure: Because the biosphere plays a key role in the flux of energy from the surface to the atmosphere, it also contributes to the structure of the atmosphere. Three major fluxes are important: the direct transfer of heat from the surface to the atmosphere by conduction and convection (sensible heating), the energy flux to the atmosphere carried by water ...
Jul 1, 2024 · Climate - Ocean-Atmosphere Interaction: The circulation of the ocean is a key factor in air temperature distribution. Ocean currents that have a northward or southward component, such as the warm Gulf Stream in the North Atlantic or the cold Peru (Humboldt) Current off South America, effectively exchange heat between low and high latitudes. In tropical latitudes the ocean accounts for a third ...
Jul 1, 2024 · The equatorial gravity of the planet, 896 cm (29.4 feet) per second per second, is only 74 percent of its polar gravity. Saturn is 95 times as massive as Earth but occupies a volume 766 times greater. Its mean density of 0.69 gram per cubic cm is thus only some 12 percent of Earth’s.
4 days ago · Mars - Atmosphere, Climate, Dust Storms: The Dutch American astronomer Gerard P. Kuiper ascertained from telescopic observations in 1947 that the Martian atmosphere is composed mainly of carbon dioxide. The atmosphere is very thin, exerting less than 1 percent of Earth’s atmospheric pressure at the surface. Surface pressures range over a factor of 15 because of the large altitude variations ...
1 day ago · Air pollution is the contamination of air due to the presence of substances called pollutants in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. It is also the contamination of the indoor or outdoor environment either by chemical, physical, or biological agents that alters the natural features of the atmosphere.
