Generally it stays blue, it just gets darker and paler the higher you go. Everntually it turns black (pilots in spy planes and astronauts report this). It will turn red or different colors at sunrise/sunset and if there is a high amount of dust in the atmosphere.

Does the troposphere have oxygen?
Oh yes. The troposphere is the lowest level of the atmosphere, the level that we live and breathe in, and it does have lots of oxygen in it, until you get to very high altitudes.
Identify the high- speed stream of particles beating against the outer layer of Earth's atmosphere?
Solar Wind
What is the distance from earth's surface to the end of earths atmosphere?
The Earth's atmosphere extends anywhere from 250-400 miles off the surface, depending on where you are standing. Near the equator, it is thicker due to the heat from the surface and cloud reflection, and the high moisture and humidity.
Is there ice in the atmosphere?
no but you have to answer to your teacher. Edit : Yes, there is a small amount of ice in the Earth's atmosphere in the form of high altitude clouds. It's cold enough for water to become little ice crystals.
The largest and outermost layer of the Earth's atmosphere the exosphere extends out to what maximum distance from Earth?
The exosphere goes from about 400 miles (640 km) high to about 800 miles (1,280 km).
How come astronomers prefer to observe the stars from high altitudes?
Earth's atmosphere, particularly the humidity in the atmosphere. causes blurriness in astronomical images. At high altitudes, the humidity is very low, and there is less atmosphere to peer through.
What characteristic of the atmosphere changes with altitude?
The temperature and level of oxygen. High altitudes sometimes have more snow and low altitudes are usually drier.
What does a large temperature gradient at high altitudes of the atmosphere cause?
Polar jet streams
What does large temperature gradient at high altitudes of the atmosphere cause?
Polar jet streams
What is neptunes atmospehere like?
At high altitudes, Neptune's atmosphere is 80% hydrogen and 19% helium.
Global winds and pressure systems?
exist at the earth's surface and at high altitudes
How are clouds at high altitudes different from clouds that form close to Earth's surface?
no
Why is it more difficult to breath at the top of a mountain?
This is due to the thinness of the atmosphere at high altitudes (e.g. the top of a mountain). The thinness is caused by the loss of molecules to space due to the slight lessening of gravity's pull at high altitudes.
Why do clouds usually form high in the sky instead of near earths atmosphere?
Clouds are in earth's atmosphere. Clouds form whem moisture in the air condenses, and usually conditions mnear the gcround are too warm for moisture to condense. Instead, clouds form at higher altitudes where it is cooler.
Are parachutes faster at high altitudes or low altitudes?
it is faster at a higher altitude because there are less air pressure when you're away from the Earth. There are more air pressure as you come to Earth so it becomes slower.
Cirrus clouds appear at low to high altitudes?
just high altitudes
Why are ultraviolet rays more dangerous on high mountains?
At high altitudes, where the air and cloud cover are thinner, it allows more damaging UV rays to get through the atmosphere.
