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?
mesopause
What is the name for the coldest point in the atmosphere?
mesopause
What is the approximate temperature of the mesopause?
85-90
Where is the mesopause located?
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.
Does the thermosphere have a high or low density?
The thermosphere has lower density than the layers below it but higher than the exosphere above it.The density of the Earth's atmosphere decreases nearly exponentially with altitude. At 400 km altitude the density is typically about 6g/m3 . This changes considerably when there is a solar storm.The air density is so low in this layer that most of the thermosphere is what we normally think of as outer space. In fact, the most common definition says that space begins at an altitude of 100 km (62 miles), slightly above the mesopause at the bottom of the thermosphere.
As altitude increases from the tropopause to the mesopause the atmospheric temperature will?
the temp stays the same
Does the temperature increase with altitude in the mesosphere?
it decreses as you go up. At the stratopause the temp is +4C, and at mesopause it is - 90C.
What gases are in the mesopause?
The mesopause contain carbon dioxide.
What is the boundary between mesosphere and thermosphere?
mesopause
How does altitude affect temperature on earth?
It depends on the on what sphere of the atmosphere you are talking about. At ground level (troposhere) it gets colder as altitude rises. Once the altitude reaches the stratosphere the temperature becomes warmer then cools down again as it reaches the stratopause, and continues to decline as altitude increases in the mesophere until the mesopause. The temperature then rises significantly when the altitude is high enough to be considered the thermosphere.
In what layer of the atmosphere do temperatures rise with altitude A. Troposphere B. Stratosphere C. Mesosphere D. Mesopause?
THE ANSWER IS B the stratosphere a.k.a. layer S temperatures increase in this layer
What is the temperature of the mesopause in degrees Celsius?
the mesopause is the boundary between the thermospere and the mesospere
The upper layer of the mesosphere is?
mesopause
What do the stratopause tropopause and the mesopause all have in common?
The stratopause, tropopause, and mesopause are all interfaces between two layers of the atmosphere.
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.
What is the name for the coldest point in the atmosphere?
mesopause
What is the approximate temperature of the mesopause?
85-90
