Eventually the air outside becomes thinner than the air in the balloon, so it can no longer float
Weather balloons are sometimes used to obtain meteorological data from high altitudes.
They fly at low altitudes because if you fly too high, the balloon may pop. A2: Above seems unlikely, as the balloon is open at its lower end. Mainly I think because they are generally used for passenger viewing flights and the general public would not have the clothing for high altitudes as well as not wanting to be very high since the purpose of the flight is to view the terrain below. The balloon works by making the air inside hotter and less dense than the surrounding air, so as it rises it needs to use more fuel to achieve this as the surrounding air gets less dense. There must be an effective max height for hot air balloons but I don't know what the record is.
Cirrocumulus cloud is a clous that often appears at high altitudes.
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.
Hot air balloons can fly at almost any altitude they choose. The height of the balloon flight is determined primarily by the pilot. Most balloon flights are tourist sightseeing flights or just fun flying by sport pilots. These flights are typically performed between 500 and 2000 feet above the ground. Also balloons must comply with the air traffic control regulations which limit where and how high balloons may fly unless they carry special navigation and communication equipment. On November 26, 2005, Vijaypat Singhania set the world altitude record for highest hot air balloon flight, reaching 21,027 meters (68,986 feet) above sea level. This flight was done in India under special permission from Indian authorities using a specially designed hot air balloon. Don Boyer Hot Air Balloon Pilot New Mexico, USA
Yes, deflated balloons can be brought on a plane in both carry-on and checked luggage. However, inflated balloons are not allowed on planes due to the risk of bursting at high altitudes.
because ok high altitudes
At very high altitudes, the air is thin and contains lower levels of oxygen. This can make it difficult to breathe and may lead to symptoms of altitude sickness such as headache, fatigue, and dizziness. It is important to acclimate gradually when ascending to high altitudes to avoid these effects.

Yes, you can take balloons on a plane, but there are restrictions and guidelines to follow. Balloons must be uninflated and packed in your carry-on luggage. Inflated balloons are not allowed due to the risk of bursting at high altitudes. It's best to check with your airline for specific rules and regulations.
It keeps us all from blowing up and popping like balloons, and it also makes it possible for us to breathe.
After weather balloons are released into the atmosphere, they ascend to high altitudes, collecting data on temperature, humidity, and pressure. Eventually, the balloons burst due to low air pressure, and a parachute deploys to slow their descent. The instruments attached to the balloon are then retrieved for analysis of the gathered data.
I would assume that they would pop somewhere above the troposphere at about 35 kilometers, because it is said that balloons pop when they enter the stratosphere which is located directly above the troposphere. The troposphere is around 30 kilometers thick.
just high altitudes
The air is thicker at lower altitudes, we know that sound travels much better when it can move through solid mass. As you climb, the air starts to get thinner. It becomes much more difficult to do anything at high altitudes, including keeping a plane aloft, keeping warm, and of course projecting sound.
Weather balloons work by carrying instruments called radiosondes that measure various atmospheric parameters such as temperature, humidity, and pressure as they ascend through the atmosphere. The balloons are filled with helium or hydrogen gas, which causes them to rise and reach high altitudes where the data can be collected and transmitted back to the ground station.
It is not so much as the composition that is important, it is that at higher altitudes there is less air. Air is about 20% oxygen, but the higher up you go in altitude, the thinner air will have less oxygen. That's what makes breathing more difficult at higher altitudes.
