The approximate temperature of the sun's surface is around 5,500 degrees Celsius (9,932 degrees Fahrenheit).
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.
Modern studies reveal that the mesopause consists of two minima - one at about 85 km and a stronger minimum at about 100 km.
From Wikipedia:Temperature decreases with height in the mesosphere. The mesopause, the temperature minimum that marks the top of the mesosphere, is the coldest place on Earth and has an average temperature around −100 °C (−148.0 °F; 173.1 K)the mesosphere is the coldest layer in the atmosphere. It contains the ozone.OK!! the answer above is incorrect the coldest layer in the atmosphere is the Mesopause its the thin layer between the Mesosphere and Thermosphere. Also the Ozone is in the Stratosphere.Actually its correct because the mesopause is a part of the mesosphere....ok the 1st and 3rd answers are wrong! i should know im learning this in my 7TH GRADE SCIENCE CLASS! the ozone is in the stratosphere, the second closest layer to the earth. STUPIDS!
Mesopause is located between the mesosphere and the thermosphere atmospheric regions. It actually consists of two minima, at two different altitudes, the first being at 52 miles, and the second, at 62 miles above sea level.
there are two mesosphere boundaries the first mesopause is at about 85 km and the second more definite boundary is at about 100km.
the mesopause is the boundary between the thermospere and the mesospere
The mesopause contain carbon dioxide.
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.
The stratopause, tropopause, and mesopause are all transitional boundaries in the Earth's atmosphere between different layers. They mark the upper limits of the stratosphere, troposphere, and mesosphere, respectively. These boundaries are characterized by significant changes in temperature and atmospheric properties.
The height of the tropopause typically ranges from 8 to 18 kilometers above the Earth's surface. The temperature at the tropopause is around -60 degrees Celsius on average, but this can vary depending on the location and season.
mesopause
The approximate temperature of a plasma stream is typically around 10,000 to 100,000 degrees Celsius.
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.
