why is the sky blue?

[trevorjohnson83]

So everyone says Rayleigh scattering. Other causes: Gravitational blue shift, density of the atmosphere, how much the sun heats the atmosphere. I wonder since the sky is red on planets beyond earth, perhaps the sun is a red star, meaning it's on its oxygen burning stage?

God wants it that way

I believe the sky is also blue on mars for part of the day. Depends on the atmosphere and distance light waves travel through it. Blue light is the shorter wavelength and scatters more. The reds and yellows are longer wavelength and cover a greater distance

I just assumed it was because of all the water, but not sure.

It’s light waves… what we see is affected by heat, distance atmosphere etc. visually it does seem like it’s just reflecting the ocean water but it’s the opposite. Ocean water is clear. Green maybe with algae. It only looks blue because of the sky

Gravitational shift is to the red spectrum. The average absorption of energy of the gas in the atmosphere gives it a blue hue.

It is every color except blue. What you see is what is reflected away.

When does the debate on, why are we carbon based life forms start?

Other causes according to who?

Gravitational blue shift

At any given moment, the Earth and the Sun are extremely close to equilibrium. There is no gravity to cause a shift.

density of the atmosphere

Density can alter the magnitude of other effects but does nothing on its own. It's like saying the color of your dog's hair determines its weight.

how much the sun heats the atmosphere.

The blue of the sky has no temperature dependence.

The Martian sky is reddish from suspended dust. If the sun were in its oxygen burning stage, it would be obvious to us from its spectrum.

the sky is both blue and red, cough cough, the exact same two colors that are most commonly scattered? coincidentally the same two colors of red shift blue shift? Isn't that amazing! your stupid dinosaur theory az put by youses!

aw I have found the answers just like creeck, next the quiz

does scattering the light mean that the atmosphere casts a shadow on the earth?

Scattering of light in the atmosphere does not literally cast a shadow on the Earth in the same way that an object blocks light to create a shadow. However, it does have significant effects on how we perceive light and shadows. Here’s how it works:

1. Scattering of Light​

• Rayleigh Scattering: This occurs when light interacts with small particles in the atmosphere, such as air molecules. It is responsible for the blue color of the sky, as shorter wavelengths (blue light) are scattered more than longer wavelengths (red light).
• Mie Scattering: This occurs with larger particles, such as dust or water droplets, and affects how light is scattered, contributing to phenomena like the white appearance of clouds.

2. Effects on Shadows​

• Diffusion of Light: When sunlight enters the atmosphere, scattering can diffuse the light, making shadows less sharp and more illuminated. This means that areas that would normally be in shadow might still receive some indirect light due to scattering.
• Clouds and Shadows: Clouds can block sunlight and create shadows on the Earth. The scattering of light by clouds can also lead to a softening of shadows in areas that are partially shaded.

3. Atmospheric Effects​

• Twilight and Dusk: Scattering causes the sky to appear illuminated during twilight, even after the sun has set, affecting how shadows are perceived.

Conclusion​

While the atmosphere does not cast a shadow in a traditional sense, scattering does influence how light interacts with the Earth’s surface, affecting visibility and the nature of shadows.

quiz time, yay!!!!

question one: your at the creek with a friend, someone named creeck comes babbling down the river backwards in a canoe. Describe why creeck casts no shadow according to the science of Rayleigh scattering. ( hint hint Use fast hand waving to show that there is no shadow)

question two: Assume a bus is traveling at a speed of 60 mph. what way is it possible that the bus scatters the light since all things with color? (hint yellow)

question 3: scatterifying the light as it comes in to the atmosphere or the bus makes them colorful? but why only two colors to the sky when the bus is one? write an answer demanding that two is bigger and better than one.

question 4: The yellow bus flies into the sky where its blue scattering around like you wouldn't believe! describe how the bus is green but we only perceive it still as yellow because of rayleigh scatter 'n.
