What are some reasons that the sky is blue?

The amount of scattering depends on the frequency of the light. Blue light, having a higher frequency, scatters more than lower frequencies (Which pretty much pass straight through the atmosphere). This scattering of blue light more than the other visible frequencies results in us seeing the sky as blue.
The_Thinker said:The reason water is blue, is because of the reflection of the blue sky on the water... that's all... water isn't blue...

Did it scatter? Or was it something else?GENIERE said:You made me spill my coffee.
Things are the color that they are due to teh frequencies of light that emerge from them. Ignoring whatever might be in the water (algae, mud, red tide etc) oceans are gree-blue because that is the light that scatters back out of the oceans.Mk said:So is water blue because water is blue? Or is it scattering? Or something else?
The sky appears blue because of the way sunlight interacts with Earth's atmosphere. When sunlight enters the atmosphere, it is scattered by the air molecules. The blue light has a shorter wavelength and is scattered more easily, making it more visible to our eyes.
Yes, the color of the sky can change throughout the day depending on the angle of the sun and the amount of particles in the air. During sunrise and sunset, the light travels through more of the atmosphere, causing longer wavelengths of light to be scattered and giving the sky a range of colors from red to orange.
No, the color of the sky on other planets depends on the composition of their atmospheres. For example, on Mars, the sky appears reddish due to the presence of iron oxide in the atmosphere. On Saturn's moon, Titan, the sky appears orange due to the presence of hydrocarbons.
The color of the sky can vary based on the amount of moisture and particles in the air, as well as the time of day. The more water vapor and particles in the air, the more the blue light is scattered and the paler the sky appears. Additionally, during sunrise and sunset, the light must travel through more of the atmosphere, resulting in a deeper blue color.
The color of the sky does not directly impact weather, but it can provide clues about the weather conditions. A bright blue sky can indicate clear and sunny weather, while a darker blue or gray sky can indicate the presence of clouds and possible rain or storms. However, it is important to note that the color of the sky is not always a reliable predictor of weather.
