What chemicals are destroying the ozone layer?
What chemicals are destroying the ozone layer?
Ozone depleting substances are chemicals that destroy the earth’s protective ozone layer….They include:
- chlorofluorocarbons (CFCs)
- halon.
- carbon tetrachloride (CCl4)
- methyl chloroform (CH3CCl3)
- hydrobromofluorocarbons (HBFCs)
- hydrochlorofluorocarbons (HCFCs)
- methyl bromide (CH3Br)
- bromochloromethane (CH2BrCl)
Which chemical was identified as an ozone destroyer and has been banned?
The chemical, trichlorofluoromethane or CFC-11, has been banned around the world since 2010 and is a potent destroyer of ozone, which protects life on Earth from UV radiation, and strong greenhouse gas.
Which element destroys ozone most?
chlorine
How high are planes in the sky?
According to USA Today, the common cruising altitude for most commercial airplanes is between 33,000 and 42,000 feet, or between about six and nearly eight miles above sea level. Typically, aircraft fly around 35,000 or 36,000 feet in the air.
Do fighter pilots get shorter?
TIL fighters pilots lose an average of 1 inch of height every time they use the ejection seat, due to the amount of G’s placed on their body.
Do planes fly over Everest?
Airplanes often avoid air paths that take them over Mt Everest or the Pacific Ocean. This is because “the Himalayas have mountains higher than 20,000 feet, including Mt Everest standing at 29,035 feet. However, most commercial airplanes can fly at 30,000 feet.”
How cold is the air at 35000 feet?
about -54C
What happens if a plane flies too high?
If a passenger jet flies too high it reaches a point called ‘Coffin Corner’. This is the point at which the aircraft’s low speed stall and high-speed buffet meet and the plane can no longer maintain its altitude which forces it to descend.
Can planes fly at 50000 feet?
Normally, passenger jets or airplanes, fly can fly at an altitude, maximum of 42000 feet. Currently, no passenger airplanes are “able” to fly at 50,000 feet or above. Because, at these altitudes, air density is very low, which wouldn’t sustain the heavy weight of the passenger aircrafts.
What happens if a plane flies into space?
If an airplane flies in space, it won’t be able to suck in fresh air with which to supply its engines, resulting in loss of propulsion. The bottom line is that airplanes can’t fly in space because there is no air in space. Airplanes rely on air to produce both lift and propulsion.
What happens if a helicopter flies too high?
What Happens If a Helicopter Flies Too High? As the helicopter ascends, the air begins to thin. With thinner air, the main rotor becomes less efficient. When the blades can no longer generate enough lift to keep ascending, the helicopter reaches its maximum operating envelope (the coffin corner).
How high can a helicopter fly?
How High Can a Helicopter Fly?

| Bell UH-1 Iroquois | 1956 | 14,500 feet |

What is the maximum range of a helicopter?
5000 feet
Can a helicopter across the Atlantic?
Two Ohioans made the first successful crossing of the Atlantic Ocean in a helicopter. The pair successfully flew across the Atlantic Ocean, landing in Prestwick Scotland. The flight covered 3,535 miles and took forty-two hours, twenty-five minutes to complete.
Do helicopters hit turbulence?
Bumps or turbulence in helicopters are basically non-existent. Helicopters ride out turbulence thanks to their sleek bodies and flexible blades- which means passengers won’t feel a thing! If turbulence is severe, we simply do not fly.
