A glowing sunset occurs when the sun dips below the horizon, casting vibrant colors across the sky. This phenomenon is caused by the scattering of sunlight through the Earth's atmosphere, which filters out shorter wavelengths of light. As a result, longer wavelengths, such as reds and oranges, become more prominent, creating a stunning visual display. The intensity and hues of a glowing sunset can vary based on factors like weather conditions, pollution, and geographic location. For example, sunsets over oceans often appear more vivid due to the reflection of light on water. Locations like Grand Canyon or Santorini are famous for their breathtaking sunset views.
