What is another word for mesosphere?
Pronunciation: [mˈɛsəsfˌi͡ə] (IPA) 
The mesosphere is the layer of the Earth's atmosphere that lies between the stratosphere and the thermosphere. This region generally extends from about 50 to 85 kilometers above sea level. It is a critical area that helps protect the Earth from harmful ultraviolet radiation and other space debris. Some synonyms for the mesosphere include the middle atmosphere or mid-latitude atmospheric region. It is also referred to as the mesopause region, as this is where the temperature gradient changes rapidly, creating an atmospheric boundary. Studying the mesosphere is essential for understanding our planet's climate and how it interacts with space.
