These well-lit regions are mostly cities (urban). Cause Light pollution occurs when outdoor lights are aimed upwards and sideways; the light scatters in the atmosphere and reflects back to the ground. As a result the sky glows. Particles responsible for air pollution‚ in the atmosphere‚ emphasize light pollution by enhancing the amount of light scatter. Effect City lights reduce the views of the night skies. Light from the urban areas compete with natural light from stars and planets‚ which
