Modern studies reveal that the mesopause consists of two minima - one at about 85 km and a stronger minimum at about 100 km.

What is the boundary between mesosphere and thermosphere?

The boundary between the mesosphere and thermosphere is called the mesopause. It is located at an altitude of about 80-85 kilometers (50-53 miles) above the Earth's surface. It is a transition region separating the cooler mesosphere below from the hotter thermosphere above.


What is the approximate temperature of the mesopause at an elevation of 68 kilometers above sea level?

The mesopause, located at an altitude of about 68 kilometers (approximately 42 miles) above sea level, typically has temperatures around -90 degrees Celsius (-130 degrees Fahrenheit). This layer marks the transition between the mesosphere and the thermosphere, where temperatures begin to rise again. The extreme cold at the mesopause is due to the low density of air and the limited absorption of solar radiation at that altitude.


What layer in the atmosphere has an upper limit called the mesopause?

The layer in the atmosphere with an upper limit called the mesopause is the mesosphere. The mesosphere is situated above the stratosphere and below the thermosphere, extending from about 50 to 85 kilometers (31 to 53 miles) above the Earth's surface. The mesopause marks the transition between the mesosphere and the thermosphere, where temperatures begin to increase with altitude.


What is the approximate temperature of the mesopause?

The temperature of the mesopause can vary depending on factors such as altitude and time of year, but it is generally around -90 to -100 degrees Celsius (-130 to -150 degrees Fahrenheit). This layer, which is about 85-100 km (53-62 miles) above the Earth's surface, is where the Earth's atmosphere transitions into space.


Where does the thermosphere start?

The thermosphere starts at an altitude of around 80 kilometers above Earth's surface. It is the layer of the Earth's atmosphere that extends from the mesopause (top of the mesosphere) to the exosphere.

As altitude increases from the tropopause to the mesopause the atmospheric temperature will?

Decrease. The tropopause marks the boundary between the troposphere and the stratosphere, where temperature generally decreases with altitude. This trend continues through the stratosphere and into the mesosphere until reaching the mesopause where temperatures are at their lowest in the upper atmosphere.

What gases are in the mesopause?

The mesopause contain carbon dioxide.


What happens to the temperature in the mesosphere?

The temperature in the mesosphere decreases with altitude, reaching its lowest point at the mesopause, the boundary between the mesosphere and thermosphere. This cooling effect is due to the diminishing density of gas molecules in this region.

What is the temperature of the mesopause in degrees Celsius?

the mesopause is the boundary between the thermospere and the mesospere


What is the approximate altitute of the mesopause in the atmosphere?

there are two mesosphere boundaries the first mesopause is at about 85 km and the second more definite boundary is at about 100km.


Does the temperature increase with altitude in the mesosphere?

No, the temperature in the mesosphere actually decreases with altitude. The mesosphere is the third layer of Earth's atmosphere, located above the stratosphere, and it is where temperatures can drop as low as -90 degrees Celsius due to its decreasing density and distance from the Earth's surface.
