What height is the stratosphere at?

around 31 miles Stratosphere. The Stratosphere extends around 31 miles (50 km) down to anywhere from 4 to 12 miles (6 to 20 km) above the Earth's surface. This layer holds 19 percent of the atmosphere's gases but very little water vapor. In this region the temperature increases with height.

Is 39000 ft of altitude in the stratosphere?

The height of the stratosphere changes depending on the part of the planet. It can be 66,000 feet high near the equator, but it gets significantly lower when we approach the poles. There, the stratosphere begins at heights of just 23,000 feet.

What is the height and temperature of the stratosphere?

The stratosphere is located above the troposphere and extends up to about 50 km (30 miles). Above the tropopause and the isothermal layer in the lower stratosphere, temperature increases with height. Temperatures as high as 0 °C (32 °F) are observed near the top of the stratosphere.

What are the 7 layers of atmosphere?

The different layers of the atmosphere

The Troposphere. This is the lowest part of the atmosphere – the part we live in. …
The Stratosphere. This extends upwards from the tropopause to about 50 km. …
The Mesosphere. …
The Thermosphere and Ionosphere. …
The Exosphere. …
The Magnetosphere.

Can birds fly in the stratosphere?

The stratosphere contains roughly 20 percent of the atmosphere's mass. Because bacterial life can survive in the stratosphere, this layer of the atmosphere belongs to the biosphere. Some species of birds have even been reported to fly in the lower levels of the stratosphere.

Can planes fly at 50000 feet?

The highest that a commercial airplane can fly is 45,000 feet. Most military planes fly at around 50,000 feet and sometimes higher. Some rocket-powered planes can fly as high as 100,000 feet but they are specially designed for this purpose.

Why do commercial planes fly at 35000 feet?

The biggest reason for this altitude lies in fuel efficiency. The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed. Less wind resistance, more power, less effort, so to speak.

Do planes fly in the stratosphere?

Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratosphere is very dry air and contains little water vapor. Because of this, few clouds are found in this layer and almost all clouds occur in the lower, more humid troposphere.

What’s the hottest layer of Earth?

core Earth's core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly-solid mantle. The core is found about 2,900 kilometers (1,802 miles) below Earth's surface, and has a radius of about 3,485 kilometers (2,165 miles).

Where is the ozone layer?

the stratosphere The Earth's ozone layer. The ozone layer lies approximately 15-40 kilometers (10-25 miles) above the Earth's surface, in the stratosphere.

Can humans breathe in the stratosphere?

2.1 The Density and Temperature of Air. The stratosphere is not a good place to be. First, the ozone in the stratosphere, which protects us from biologically destructive solar ultraviolet light, exists at such high levels that the air itself is toxic. Second, even this toxic air is much too thin for normal breathing.

Why do planes fly at 32000 feet?

The biggest reason for this altitude lies in fuel efficiency. The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed.

Can a plane fly over Mount Everest?

Tim Morgan, a commercial pilot writing for Quora says aircraft can fly above 40,000 feet, and hence it is possible to fly over Mount Everest which stands at 29,031.69 feet. However, typical flight routes do not travel above Mount Everest as the mountains create unforgiving weather.

How high can birds fly?

Many bird species live in habitats that are over 13,123 feet (4,000 m) above sea level, and others routinely fly to altitudes of approximately 10,000 to 13,000 feet (3,000 to 4,000 m), especially when they're migrating, said Graham Scott, an assistant professor of biology at McMaster University in Ontario, Canada.

Why do planes not fly over the Pacific?

Flying over the Pacific Ocean is avoided by most airlines for most flights because it usually doesn't make sense to fly over it when shorter and safer routes exist. The Pacific Ocean is also more remote and less safe than the Indian and Atlantic Oceans to fly over, resulting in a higher chance of a plane crashing.

Can you breathe in the stratosphere?

What is the coldest layer?

Answer and Explanation: The mesosphere is the coldest layer because it has essentially nothing to heat it.

Which place is center of Earth?

In 2003, a refined result was yielded by Holger Isenberg: 40°52′N 34°34′E, also in Turkey, near the district of İskilip, Çorum Province, approx. 200 km northeast of Ankara. In 2016, Google Maps marked Isenberg's result of 40°52′N 34°34′ECoordinates: 40°52′N 34°34′E as the geographical center of Earth.

Which is the coldest layer?

Mesosphere Mesosphere, altitude and temperature characteristics The top of the mesosphere is the coldest area of the Earth's atmosphere because temperature may locally decrease to as low as 100 K (-173°C).

Who discovered ozone hole?

In 1985 Jonathan Shanklin was a junior researcher at BAS when he discovered a hole in the invisible shield that protects us from solar radiation. We catch up with him to learn about his work and how it has made a difference. It's 36 years since scientists first discovered the hole in the ozone layer.

Do planes fly in stratosphere?

Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratosphere is very dry; air there contains little water vapor. Because of this, few clouds are found in this layer; almost all clouds occur in the lower, more humid troposphere.

Why do planes not fly over the Pacific Ocean?

Weather Patterns. Most flights are planned to minimize the time spent over bodies of water, since storms are more likely to occur over water than land. The weather over the Pacific Ocean is often turbulent, and there are many thunderstorms in parts of the Pacific, so it's not a safe environment to fly a plane.

Can helicopters reach Everest?

Choppers reportedly also flew ropes and other equipment to climbers stranded above the Khumbu icefall, which also sits nearly 18,000 feet above sea level. And helicopters have actually made it even to the peak of Everest before, the first time in 2005.

Why can’t helicopters go to Everest?

The air is just too thin for most helicopters to generate enough lift to remain airborne. If the helicopter is equipped to reach that height, making the landing is still an incredibly delicate affair.

How high can a bee fly?

On average, bees were capable of hovering at air pressure equivalents exceeding 8000 m (maximum flight altitude median: 8039 m, mean: 8331 m, range: 7820–9125 m; figure 1).

How fast do planes fly?

around 460-575 mph Most commercial aircraft typically fly at around 460-575 mph, or 740-930 km/h, according to Flight Deck Friend. But private jet speed can vary depending on a variety of factors, such as the weight onboard and the weather conditions.

Why don’t we fly from Alaska to Russia?

The Alaska ADIZ is a buffer zone of thousands of square miles that isn't sovereign airspace—Russian planes can legally fly there—but entering the zone means a plane could conceivably enter U.S. airspace in a relatively short amount of time.

Why do flights to Japan go over Alaska?

Commercial airlines typically fly a Northern curved route that goes over Canada and Alaska. Therefore, they spend less time over the Pacific Ocean, allowing for emergency landings if needed.

At what height is there no oxygen?

26,000 ft It refers to altitudes above a certain point where the amount of oxygen is insufficient to sustain human life for an extended time span. This point is generally tagged as 8,000 m (26,000 ft, less than 356 millibars of atmospheric pressure).
