What is a stable atmosphere and how can it form??
What will be an ideal response?
ANSWER: ?Atmospheric stability is a condition of equilibrium. Air is in stable equilibrium when, after being lifted or lowered, it tends to return to its original position—it resists upward and downward air motions. Air that is in unstable equilibrium will, when given a little push, move farther away from its original position—it favors vertical air currents. In addition, the atmosphere is stable when the environmental lapse rate is small; that is, when the difference in temperature between the surface air and the air aloft is relatively small. Stable atmospheres form when surface air cools or higher-altitude air warms, or both.
