The mesosphere is the third layer of Earth's atmosphere, located above the stratosphere and below the thermosphere, stretching approximately 50 to 85 kilometers (31 to 53 miles) above sea level. In this layer, temperatures decrease with altitude, reaching as low as -90 degrees Celsius (-130 degrees Fahrenheit), and it is where most meteors burn up upon entering the atmosphere. Remember, the mesosphere is crucial for protecting our planet from meteor impacts and understanding atmospheric science!

Send FeedbackMesosphere: The mesosphere is the third layer of Earth's atmosphere, located above the stratosphere and below the thermosphere. It extends from about 50 kilometers (31 miles) to approximately 85 kilometers (53 miles) above sea level.
In the mesosphere, temperatures decrease with altitude, reaching the lowest temperatures in the atmosphere at approximately -90 degrees Celsius (-130 degrees Fahrenheit) near its top. This significant temperature drop occurs because there is less solar radiation available at this altitude compared to the layers below. The mesosphere plays a crucial role in atmospheric dynamics and the overall climate system. Unlike the layers above it, the mesosphere contains very few air molecules, which makes it difficult for sound to travel or clouds to form.
Example: An excellent example of a phenomenon that occurs in the mesosphere is the appearance of noctilucent clouds. These rare clouds form at high altitudes in the mesosphere during summer, appearing glowing at twilight due to sunlight scattering off ice crystals. They serve as an indicator of climate change and the increasing presence of water vapor in the upper atmosphere.
Did you know that the mesosphere is also where many rockets reach their highest altitude before falling back to Earth? This layer is also vital for thermal radiation escaping from the Earth.
The mesosphere, despite being one of the less studied layers of the atmosphere, is fascinating for several reasons. For instance, it experiences atmospheric waves, which can disrupt normal wind patterns and lead to the creation of gravity waves. These waves can travel vast distances and impact weather patterns. The mesosphere also interacts with the layers above and below it, leading to complex dynamics that scientists are still researching. The boundary between the mesosphere and the thermosphere—known as the mesopause—is where the temperatures are at their lowest. This unique characteristic influences various atmospheric processes, including the movement of pollutants and greenhouse gases. Furthermore, the energy transfer between the mesosphere and the thermosphere has implications for satellite operations and deep-space communication technologies. Understanding the properties of the mesosphere is crucial for improved weather forecasting, climate models, and future explorations of near-Earth space.
The mesosphere is a fascinating layer of Earth's atmosphere, lying above the stratosphere and below the thermosphere. It extends from approximately 50 kilometers (31 miles) to 85 kilometers (53 miles) above sea level. In this layer, temperatures drop significantly with elevation, with the coldest temperatures found near the top of the mesosphere. The characteristics of the mesosphere can be summarized as follows:
Example: An interesting phenomenon within the mesosphere is the formation of noctilucent clouds. These clouds appear at high altitudes and are made of ice crystals. They glow beautifully during twilight, reflecting sunlight that illuminates them from below the horizon.
Fun fact: Most meteors burn up in the mesosphere due to the friction caused by entering the layer at high speeds!
The dynamics of the mesosphere involve intriguing processes. It experiences various atmospheric waves influenced by both the lower atmospheric layer and the thermosphere above. These waves can lead to the formation of gravity waves, which may extend their effects across large distances, impacting the Earth's weather patterns. As one travels through the mesosphere, the energy transfer from this layer to the thermosphere can greatly influence satellite operations, particularly regarding communication and the temperature of the upper atmosphere. Scientists continue to study the mesosphere due to its role in atmospheric chemistry and potential implications for climate change.
The temperature in the mesosphere exhibits a remarkable pattern characterized by significant decreases with increasing altitude. This phenomenon is primarily due to the thinning of air and fewer air molecules available to absorb and retain heat. The mesosphere is located above the stratosphere and extends from approximately 50 kilometers (31 miles) to 85 kilometers (53 miles) above sea level. As one ascends through this layer, temperatures can plummet to around -90 degrees Celsius (-130 degrees Fahrenheit), making it the coldest layer of the atmosphere. Factors influencing temperature in this layer include:
Example: A specific temperature profile observed in the mesosphere shows that at an altitude of 70 kilometers, temperatures might be around -50 degrees Celsius (-58 degrees Fahrenheit), illustrating the continual decline as altitude increases.
Remember that the mesosphere is where meteors usually burn up upon entering Earth's atmosphere due to the extreme friction and temperature conditions present!
The unique temperature dynamics of the mesosphere are critical to understanding atmospheric science. During the summer months, the temperature can rise slightly due to increased solar radiation before dropping again during winter. Various climatic phenomena such as atmospheric tides can also influence temperature changes.
| Altitude (km) | Temperature (°C) |
| 50 | -30 |
| 60 | -50 |
| 70 | -70 |
| 80 | -90 |
The mesosphere holds many fascinating phenomena and examples that can be observed in nature. One of the most notable occurrences in this atmospheric layer is the formation of noctilucent clouds. These clouds are incredibly high in the atmosphere, typically appearing at altitudes of around 80 kilometers (50 miles) and are composed of ice crystals. Noctilucent clouds are primarily formed during the summer months and are usually visible during twilight. As the sun sets, the sunlight reflects off these clouds, creating a stunning, luminescent effect in the night sky.
Example: During a summer evening, observers in areas with clear skies may witness noctilucent clouds glowing in hues of blue and silver, showcasing how ice crystals interact with sunlight even when the sun is below the horizon.
Keep an eye out for noctilucent clouds on clear summer evenings; they are a rare atmospheric treat that typically occurs in polar regions!
In addition to noctilucent clouds, the mesosphere plays host to several other intriguing features. One such phenomenon is the burning of meteors. As meteoroids enter the mesosphere at high speeds, the friction with air molecules causes them to heat up and emit light, resulting in what we see as shooting stars. The burning of meteors in the mesosphere occurs at altitudes between 75 and 100 kilometers (46 to 62 miles). This process not only creates a dazzling light display but also contributes to the study of the composition of meteoroids, which can reveal information about the early solar system. Additionally, researchers monitor gravity waves in the mesosphere, which are ripples in the atmosphere caused by the movement of air. These waves can affect weather patterns and atmospheric circulation, demonstrating the complex relationship between the mesosphere and other layers of the atmosphere.
