Question

Quizplus · Accepted Answer

An increase in the environmental lapse rate (ELR) means that the temperature of the surrounding air decreases more rapidly with height. This creates instability as warmer air near the ground rises more easily and faster. This, in turn, creates convection currents or updrafts, making the air layer less stable.
