Question

Quizplus · Accepted Answer

Noctilucent clouds, also known as polar mesospheric clouds, are thin, wispy clouds that form in the mesosphere at high altitudes. They are only visible during twilight hours and are a unique feature of the mesosphere.

Answer C is not entirely accurate as the mesosphere is technically part of the heterosphere-lower layer, but it also includes a transition region with the upper layer of the homosphere.

Answer D is partially correct but does not provide a unique or specific characteristic of the mesosphere.
