What is the altitude of each layer of the atmosphere?

What is the altitude of each layer of the atmosphere?

Exosphere: 700 to 10,000 km (440 to 6,200 miles) Thermosphere: 80 to 700 km (50 to 440 miles) Mesosphere: 50 to 80 km (31 to 50 miles) Stratosphere: 12 to 50 km (7 to 31 miles)

What are the layers of altitude?

From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere. Troposphere. Earth’s troposphere extends from Earth’s surface to, on average, about 12 kilometers (7.5 miles) in height, with its height lower at Earth’s poles and higher at the equator.

What is the altitude of the thermosphere?

The thermosphere starts just above the mesosphere and extends to 600 kilometers (372 miles) high. Aurora and satellites occur in this layer.

What is the temperature range of the mesosphere?

The temperature ranges from negative 184 degrees Fahrenheit at the mesosphere’s upper boundary to 3,600 degrees Fahrenheit (2,000 degrees Celsius) near the upper boundary as ultraviolet and X-ray radiation from the sun is absorbed.

What is the altitude of exosphere?

There is no clear-cut upper boundary where the exosphere finally fades away into space. Different definitions place the top of the exosphere somewhere between 100,000 km (62,000 miles) and 190,000 km (120,000 miles) above the surface of Earth.

Which two layers are part of the thermosphere exosphere and ionosphere ionosphere and mesosphere mesosphere and stratosphere stratosphere and troposphere?

The different layers of the atmosphere. The atmosphere can be divided into layers based on its temperature, as shown in the figure below. These layers are the troposphere, the stratosphere, the mesosphere and the thermosphere. A further region, beginning about 500 km above the Earth’s surface, is called the exosphere.

What is the relationship between temperature and altitude in the mesosphere?

In the mesosphere, temperature decreases as altitude increases, to as low as −93°C. In the thermosphere, temperature increases at altitude increases, to as high as 1,727°C.

What does the mesosphere do?

The mesosphere is the highest of the atmospheric layers in which gases are all mixed up, instead of being layered in terms of their mass. 18. The mesosphere protects the Earth from meteors and asteroids by burning them up before they can reach its surface.

Why does the mesosphere decrease in temperature with altitude?

Temperatures in the mesosphere decrease with altitude. Because there are few gas molecules in the mesosphere to absorb the Sun’s radiation, the heat source is the stratosphere below. The air in the mesosphere has extremely low density: 99.9% of the mass of the atmosphere is below the mesosphere.

What layer in the atmosphere reaches the highest altitude?

The exosphere is the highest layer of the atmosphere. It extends up to 10,000 km (6,200 miles; 33,000,000 ft.) above the Earth. Satellites orbit the Earth in the exosphere. The atmosphere in this layer is extremely thin and atoms and molecules of air are constantly escaping into outer space.

What is the altitude of the Earths stratosphere layer?

The stratosphere is one of the 5 layers of the atmosphere, situated above the troposphere and below the mesosphere at an altitude of 10 km (6 miles) to 50 km (30 miles). It is the only atmospheric layer where temperature inversion occurs and part of the atmosphere where the ozone layer is situated.

What is the altitude of Earth’s atmosphere?

The earth atmosphere’s scale height is about 8.5km, as can be confirmed from this diagram of air pressure p by altitude h: At an altitude of 0, 8.5, and 17 km, the pressure is about 1000, 370, and 140 hPa, respectively.

What is the PSI of Earth’s atmosphere?

This U.S. customary units is not elsewhere. Normal atmospheric pressure is 14.7 psi, which means that a column of air one square inch in area rising from the Earth’s atmosphere to space weighs 14.7 pounds.
