Which statement best describes instability in the troposphere?
Answer and explanation
Correct answer: Air heated from the surface rises and creates convection
Atmospheric instability is governed by the lapse rate and buoyancy. When the ground warms air near the surface, that air becomes relatively warm and less dense, so it rises; cooler surrounding air can descend, producing convection and weather. Option B describes this process. The other choices either describe stability incorrectly or deny the presence of air and water vapour.
