there are two mesosphere boundaries the first mesopause is at about 85 km and the second more definite boundary is at about 100km.
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.
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 mesopause contain carbon dioxide.
1. There are 3 interfaces in the atmosphere. The tropopauseis between the troposphere and stratosphere. The stratopause is in between the mesosphere and stratosphere. Lastly, the mesopause is between the thermosphere and the mesosphere.
The coldest point in the atmosphere is known as the tropopause. This boundary separates the troposphere and the stratosphere, and temperatures can drop significantly as you move higher into the stratosphere.
The mesopause is located at the boundary between the mesosphere and the thermosphere, typically around 80-85 kilometers (50-53 miles) above the Earth's surface. Its thickness can vary, but it is typically quite small in comparison to other layers of the atmosphere.
The three transitional layers in the atmosphere are the tropopause, which separates the troposphere and the stratosphere; the stratopause, which separates the stratosphere and the mesosphere; and the mesopause, which separates the mesosphere and the thermosphere.
The mesopause is the third highest layer of the Earth's atmosphere, located above both the mesosphere and the stratosphere. It marks the boundary between the mesosphere and the thermosphere.
0.00005% of the atmosphere is hydrogen.
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.
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 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.
