For instance, if in the depths of the night you saw wavering white or bluish-green flames over a cemetery, you could determine based on their properties and composition that it was only low-ignition phosphine undergoing a spontaneous combustion reaction at ambient temperatures.
Or, say mountain climbers encountered an avalanche at 6,000-meter altitude, geologists would tell you that it happened because an external force like rolling rocks, footstep vibrations, and wind noise disrupted the stalemate between the cohesion and gravity within the accumulated snow. This disturbance caused the external pressure to exceed the cohesion, ultimately resulting in the avalanche.
