The atmosphere is made mostly of the gases nitrogen (78%), and oxygen (21%). Argon gas and water (in the form of vapor, droplets and ice crystals) are the next most common things. There are also small amounts of other gases, plus many small solid particles, like dust, soot and ashes, pollen, and salt from the oceans.
Nitrogen and oxygen make up most of the molecules in our atmosphere, but any gas or aerosol suspended in the air will scatter rays of sunlight into separate wavelengths of light. Consequently, when there are more aerosols in the atmosphere, more sunlight is scattered, resulting in more colorful skies.
Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
The sky is really a blanket of gas around the planet that we call the atmosphere. When planet earth formed, the atmosphere was very then and just made of hydrogen and helium. Then volcanoes started to form and pumped out other gases like carbon dioxide and water vapour (… or steam).
You asked about the sky. We know the sky is blue and the sea does reflect some of this light. So, yes, it does play a role. To sum it all up: the sea is blue because of the way water absorbs light, the way particles in the water scatter light, and also because some of the blue light from the sky is reflected.
If it really was blue light that was scattered most, then we'd see the sky as a slightly greenish blue. We don't see the greenish hue, however, because of the sky's violet light. Violet is scattered most by Earth's atmosphere, but the blue cones in our eyes aren't as sensitive to it.
The water is in fact not colorless; even pure water is not colorless, but has a slight blue tint to it, best seen when looking through a long column of water. The blueness in water is not caused by the scattering of light, which is responsible for the sky being blue.
For simplicity, scientists say that the atmosphere ends at the Kármán line, 100 km (62 miles) above sea level. That's where sky is said to become space, which is what people mean when they talk about 'the edge of space'. Beyond that line, there is not enough air to create drag.
Fortunately, Earth's atmosphere protects the Earth from most of these objects. As they fall, objects meet wind resistance from the air in the atmosphere. This resistance causes friction, which creates heat… A LOT of heat.
The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water.
So, why does it generally look yellow? This is because the Earth's atmosphere scatters blue light more efficiently than red light. This slight deficit in blue light means the eye perceives the colour of the Sun as yellow. The more atmosphere the Sun's light passes through, the more blue light is scattered.
Blue is scattered more than other colours because it travels as shorter, smaller waves. However, at sunset, light has further to travel through the atmosphere. The shorter wavelength blue light is scattered further, as the sunlight passes over a greater distance, and we see the longer wavelength yellow and red light.
Beyond the Sky is a 2018 American science fiction film written and directed by Fulvio Sestito in his directorial debut. The film stars Ryan Carnes, Jordan Hinson, Claude Duhamel, Martin Sensmeier, Don Stark, Peter Stormare, and Dee Wallace. It was acquired by RLJE Films in 2018 and was released on September 21, 2018.
Think of the Earth's atmosphere as a prism separating the sunlight into its seven colours. However, they all are not scattered the same. The shorter the wavelength, the faster the scattering upon entering the atmosphere. The more scattered a wavelength is, the better we see the colour.
The sky is falling… sort of. Over the last 10 years, the height of clouds has been shrinking, according to new research. The time frame is short, but if future observations show that clouds are truly getting lower, it could have an important effect on global climate change.
It's difficult to say what our world would be like if there were no clouds. But, says Stephens, "It's certain that our world without clouds would be nothing like what we know today." In fact, it might be much like Mars, says JPL planetary scientist David Kass.
Without clouds, average surface temperatures would rise by as much as 22 degrees Celsius. This extreme temperature spike would not only destroy the habitats of most flora and fauna, killing off whatever survived the drought, it would also melt the polar ice caps and cause massive flooding of coastal cities.
The sky is a vast, boundless expanse that never actually ends (though at some point it technically becomes space). So saying the sky, which goes on and on infinitely is the limit, is saying that there's in fact no limit at all—or, at least, there's practically or metaphorically speaking no limit.
A common definition of space is known as the Kármán Line, an imaginary boundary 100 kilometers (62 miles) above mean sea level. In theory, once this 100 km line is crossed, the atmosphere becomes too thin to provide enough lift for conventional aircraft to maintain flight.
