Oxygen
A jet-stream is a current of air high above the earth. They move eastward at altitudes of about 5 to 9-miles.
At higher altitudes, the air becomes less dense, leading to a decrease in temperature due to lower pressure and reduced heat retention from the Earth's surface. The temperature can drop as much as 3.5°F for every 1,000 feet of elevation gain, leading to the extreme cold temperatures experienced at higher altitudes.
The air pressure at the surface of the Earth is much higher (roughly 14.7 pounds per square inch) compared to the air pressure at 7 miles above Earth, which is much lower due to the thinner atmosphere at higher altitudes. The pressure decreases with increasing altitude, following the barometric formula.
Birds typically do not inhabit the stratosphere, which is located about 10 to 50 kilometers (6 to 31 miles) above the Earth's surface. Most birds fly within the troposphere, the layer of the atmosphere closest to the Earth, where they find food and suitable conditions for survival. While some birds can reach high altitudes during migration, such as the bar-headed goose, they do not sustain flight in the stratosphere where air pressure and oxygen levels are significantly lower.
Satellites are primarily located in the thermosphere, which is part of Earth's atmosphere, extending from about 80 kilometers (50 miles) above the surface to around 600 kilometers (373 miles) or more. This region includes low Earth orbit (LEO) satellites, which typically operate at altitudes between 160 to 2,000 kilometers (100 to 1,200 miles). Higher orbits, like geostationary orbit, are situated around 35,786 kilometers (22,236 miles) above Earth, well above the atmosphere's significant influence.
Cumulus clouds typically form at lower altitudes, around 1,000 to 6,500 feet above the ground. Cumulonimbus clouds, which can grow to great heights, can extend vertically up to 60,000 feet or higher in the atmosphere.
The Aurora Borealis, or Northern Lights, are typically located around 60 to 75 miles above the Earth's surface. However, they can sometimes occur at altitudes up to 200 miles.
Satellites are primarily located in space, above the Earth's atmosphere, typically in orbits that range from about 200 kilometers (124 miles) to over 36,000 kilometers (22,236 miles) above the Earth's surface. Low Earth Orbit (LEO) satellites are found at altitudes between 200 and 2,000 kilometers, while Geostationary satellites are positioned around 36,000 kilometers above the equator, allowing them to match the Earth's rotation. These altitudes are well above the atmosphere, where air resistance would impede their operation.
The mesosphere is the third layer of Earth's atmosphere, located above the stratosphere and below the thermosphere. It spans altitudes from about 31 miles (50 kilometers) to 53 miles (85 kilometers) above the Earth's surface. This layer is characterized by decreasing temperatures with increasing altitude.
Satellites typically orbit in low Earth orbit (LEO) at altitudes ranging from 160 to 2,000 kilometers, in medium Earth orbit (MEO) around 10,000 kilometers, or in geostationary orbit (GEO) at around 35,786 kilometers above Earth's equator. The altitude depends on the purpose and function of the satellite.
I'm pretty sure that it is about 6 miles from the ground to the clouds
Cumulus clouds typically form at altitudes between 1 to 6 kilometers (0.6 to 4 miles) above the Earth's surface.
