On what basis are noctilucent clouds distinguished from normal tropospheric clouds?
Answer and explanation
Correct answer: They are linked with the very high mesospheric region
Noctilucent clouds are the highest known clouds and form in the very cold upper mesosphere, near the mesopause, far above ordinary tropospheric clouds. Their great altitude and visibility after sunset or before sunrise distinguish them from normal weather clouds. Therefore option A is correct. They do not form at sea level, do not produce heavy exospheric rainfall, and are not defined simply by being below the ozone layer.
