Why are weather activities fewer in the stratosphere although weather forms in the troposphere?
Answer and explanation
Correct answer: Water vapour is low and vertical mixing is weak in the stratosphere
Weather requires moisture, temperature differences and strong vertical convection. The troposphere contains most atmospheric water vapour and is vigorously mixed because it is heated from Earth’s surface. In the stratosphere, air is comparatively dry and arranged in stable layers, so vertical movements and cloud formation are limited. Therefore option A is correct; gravity is present, the stratosphere is above the surface, and it is gaseous rather than solid.
