Which force is identified as the most significant non-thermal pressure source resisting collapse in large, cold clouds?

Answer

Turbulent motion

Turbulence, which represents the chaotic swirling motions within the gas, is cited as the most significant non-thermal pressure resisting gravitational collapse in extensive, cold molecular clouds.
