Incorrect statement: Within the mesosphere, temperature increases with increasing height.
Explanation:
- The mesosphere is the third layer of the atmosphere, located directly above the stratosphere.
- It extends from about 50 km to 80-85 km above the Earth's surface.
- This layer is characterized by a decrease in temperature with increasing height, unlike the stratosphere where temperature increases with height.
- The temperature in the mesosphere can drop as low as -100°C, making it the coldest layer of the atmosphere.
- The mesosphere is also known as the layer where meteorites burn up when they enter from space, due to the high concentration of gases such as oxygen and nitrogen, which cause friction and heat up the meteorite.
- The mesosphere is also home to a unique phenomenon called noctilucent clouds, which are thin, glowing, and wispy clouds that can be seen in the polar regions during the summer months.
In summary, the mesosphere is a unique layer of the atmosphere that is characterized by low temperatures, high atmospheric pressure, and the burning up of meteorites. Unlike the stratosphere, the temperature in the mesosphere decreases with increasing height.
