Earth atmospheric pressure is rechest in
Answers
Answer:
The atmosphere of Titan is the layer of gases surrounding Titan, the largest moon of Saturn. It is the only thick atmosphere of a natural satellite in the Solar System. Titan's lower atmosphere is primarily composed of nitrogen (94.2%), methane (5.65%), and hydrogen (0.099%).[1] There are trace amounts of other hydrocarbons, such as ethane, diacetylene, methylacetylene, acetylene, propane, PAHs[2] and of other gases, such as cyanoacetylene, hydrogen cyanide, carbon dioxide, carbon monoxide, cyanogen, acetonitrile, argon and helium.[3] The isotopic study of nitrogen isotopes ratio also suggest acetonitrile may be present in quantities exceeding hydrogen cyanide and cyanoacetylene.[4] The surface pressure is about 50% higher than Earth at 1.5 bars[5] which is near the triple point of methane and allows there to be gaseous methane in the atmosphere and liquid methane on the surface.[6] The orange color as seen from space is produced by other more complex chemicals in small quantities, possibly tholins, tar-like organic precipitates.
Earth 's atmosphere is richest in infrared radiation or IR. * The earth emits huge amount of infrared radiation and thereby makes the atmosphere richest in infrared rays. * When sunlight (solar radiation) hits the earth, some of the energy is absorbed by the earth that ultimately heats up the earth
