Question

Что такое мезосфера?

Answer 1

Это слой атмосферы на высоте от 40 до 90 км. Характиризуется понижением температуры с высотой.

Answer 2

Может мезосфера? Тогда это слой атмосферы от 40- 50 и 80-90 км

Answer 3

What is the Mesosphere?

The mesosphere is a layer of the Earth's atmosphere that is located above the stratosphere and below the thermosphere. It is the third layer of the atmosphere, extending from about 50 to 85 kilometers (31 to 53 miles) above the Earth's surface. The mesosphere is characterized by a decrease in temperature with increasing altitude, reaching its coldest temperatures near the top of the layer. The average temperature in the mesosphere can range from about -90 degrees Celsius (-130 degrees Fahrenheit) to -120 degrees Celsius (-184 degrees Fahrenheit).

Characteristics of the Mesosphere

The mesosphere is a region of the atmosphere that exhibits several unique characteristics:

1. Temperature: As mentioned earlier, the mesosphere is known for its low temperatures. The temperature decreases with increasing altitude, reaching its lowest point near the top of the mesosphere. This is primarily due to the decreasing concentration of ozone and the absence of significant heating from the Sun.

2. Auroras: The mesosphere is the region where auroras occur. Auroras, also known as the Northern Lights (aurora borealis) and Southern Lights (aurora australis), are natural light displays that occur in the polar regions. They are caused by the interaction of charged particles from the Sun with the Earth's magnetic field in the upper atmosphere, including the mesosphere.

3. Meteor Showers: The mesosphere is the layer of the atmosphere where meteoroids burn up upon entering the Earth's atmosphere. When meteoroids, which are small particles from space, collide with the Earth's atmosphere, they heat up and produce streaks of light known as meteors. These meteors are commonly seen as shooting stars during meteor showers.

4. Noctilucent Clouds: Noctilucent clouds, also called polar mesospheric clouds, are thin, glowing clouds that form in the mesosphere. They are composed of ice crystals and are visible during the summer months in the polar regions. Noctilucent clouds are the highest clouds in the Earth's atmosphere and are believed to be formed by water vapor freezing onto dust particles in the mesosphere.

Conclusion

In summary, the mesosphere is the third layer of the Earth's atmosphere, located above the stratosphere and below the thermosphere. It is characterized by low temperatures, the occurrence of auroras, the burning up of meteoroids, and the presence of noctilucent clouds. The mesosphere plays a crucial role in the Earth's atmospheric dynamics and is an area of ongoing scientific research and exploration
