Convection is the transfer of heat due to the bulk movement of molecules within fluids (gases and liquids), including molten rock ().Convection includes sub-mechanisms of advection (directional bulk-flow transfer of heat), and diffusion (non-directional transfer of energy or … At sea level, the atmospheric pressure is 14.7 pounds per square inch, or PSI. Differences in air temperature and air pressure due to uneven heating of the Earth creates? The uneven heating causes temperature differences, which in turn cause air currents (wind) to develop, which then move heat from where there is more heat (higher temperatures) to where there is less heat (lower temperatures). Atmospheric pressure, also known as barometric pressure (after the barometer), is the pressure within the atmosphere of Earth.The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa; 1,013.25 mbar), which is equivalent to 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.
