What is the name of the phenomena (driven by the scattering of light) in which mountain tops acquire a rosy or orange hue around sunrise and sunset?

Alpenglow

The correct answer is option 3. Alpenglow.

The phenomenon, driven by the scattering of light, in which mountain tops acquire a rosy or orange hue around sunrise and sunset is called Alpenglow.

Alpenglow occurs when the sun is just below the horizon, and its rays illuminate the atmosphere and clouds above the mountains. The scattered light creates the characteristic pink, orange, or reddish glow on the mountain peaks, creating a stunning visual effect. This phenomenon is particularly prominent during twilight periods, such as sunrise and sunset.
