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.
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.
Solar Wind
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.
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 exosphere goes from about 400 miles (640 km) high to about 800 miles (1,280 km).
Wind generally moves faster at high altitudes compared to the Earth's surface. This is due to the decrease in surface friction as you move higher up in the atmosphere, which allows the wind to flow more freely and at higher speeds.
The temperature and level of oxygen. High altitudes sometimes have more snow and low altitudes are usually drier.
Polar jet streams
Jet planes fly in the stratosphere, which is the second layer of Earth's atmosphere. This layer provides a stable environment for jet propulsion and allows for efficient flying at high altitudes.
Ultraviolet rays are more dangerous at high altitudes because the atmosphere is thinner, offering less protection from the sun's radiation. This means that more UV radiation reaches the earth's surface at higher elevations, increasing the risk of sunburn and skin damage. Additionally, the reflection of sunlight off snow and ice can further intensify UV exposure at high altitudes.
At high altitudes, Neptune's atmosphere is 80% hydrogen and 19% helium.
No, the Concorde was designed to operate within the Earth's atmosphere and was not capable of flying to the edge of space. It was a supersonic passenger jet that flew at high altitudes, but not high enough to reach the edge of space.
That's a trick question, since at VERY high altitudes the trend reverses momentarilly. It's dependant on what the sun can heat: at low altitudes, where the atmosphere is predominantly oxygen and nitrogen, the solid earth itself is the only heat absorber. Hence, the further you get from the warm soil of the earth, the colder you get. At very high altitudes (over 60,000 ft, I believe... higher than any mountain), larger gas molecules like Ozone, Sulfur Dioxide, etc. can absorb some heat. It's still way too cold to live there, though, so I wouldn't recommend it
no
The highest clouds in the sky, known as noctilucent clouds, are made of tiny ice crystals that form at very high altitudes in the Earth's atmosphere. These clouds typically occur at altitudes of around 50 miles (80 kilometers) above the Earth's surface in the mesosphere.
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.
The SR-71 Blackbird primarily operated in the stratosphere, which is the second major layer of Earth's atmosphere. This layer is characterized by high altitudes, low air pressure, and stable atmospheric conditions - ideal for high-speed, high-altitude flight capabilities of the SR-71.
