Question

why is the sky orange - and red at sunrise and sunset? gases absorb orange and red light. the thick atmosphere scatters all but longer wavelengths. dust scatters wavelengths are radiated from the sun in the morning and evening.

Explanation:

During sunrise and sunset, sunlight travels a longer path through the Earth's atmosphere. Shorter - wavelength colors like blue and violet are scattered more by the air molecules, while longer - wavelength colors like orange and red are scattered less and reach our eyes, making the sky appear orange and red.

Answer:

The sky appears orange and red at sunrise and sunset because the Earth's atmosphere scatters all but longer wavelengths, and orange and red light with longer wavelengths are received from the Sun in the morning and evening.
