According to Google…
The scientific answer is actually pretty interesting, and has a lot to do with the ecosystem, landscape, and something called scattering. Small particles and molecules found in the atmosphere change the direction of light rays as the sun goes up, or down. The color of the scattered light is determined by the size of molecule or particle and the actual wavelength of light. Because Arizona is generally dry, dust particles are able to float effortlessly on the breeze so there's a lot of them available for scattering. More particles equal more color.

The vast amount of loose soil gracing our state means any day has the potential to throw out an amazing array of colors as the sun breaks the horizon. We know that loose particles and molecules in the air cause scattering. And what gets these particles up from their resting spots?
That's right... Wind! Windy days inspire the movement of particles from their sedimentary state and more of them are available in the sky to scatter light.

Also clouds ☁️ help and the best sunsets typically happen when you have mid and high-level clouds covering around 25% to 60% of the evening sky When the sun is setting, its light must travel through the thickest part of the atmosphere. This causes more scattering to occur. As a result, longer wavelengths are reflected (red, orange, and yellow), creating beautiful colours in the sky.

I guess that’s why the ocean 🌊 and desert 🏜️ both have such beautiful sunsets…. sand and dust!!! 🌊 🏜️ 🥰
