No.
nitrogen-rich and oxygen-poor with some ozone
No. The mesosphere doesn't have ozone.
No, it doesn't. Mesosphere doesn't contain ozone.
Stratosphere is rich in ozone gas. It contains the ozone layer.
See "What is the ozone layer?"
stratosphere
No, the ozone layer is a region in Earth's stratosphere that contains a high concentration of ozone gas, which helps protect us from harmful ultraviolet radiation. The mesosphere is a layer of Earth's atmosphere above the stratosphere and below the thermosphere, characterized by decreasing temperatures with altitude.
The atmosphere. The stratosphere. The lower stratosphere and tropopause. The ozone layer. Pick one.
The ozone layer that separates the mesosphere from the layer below it is called the stratopause. It serves as a boundary between the stratosphere and the mesosphere, and is characterized by a temperature inversion where temperatures increase with altitude.
The layer ozone is present in the stratosphere. It protects us from the Uv rays. The layer after that is Mesosphere.
All layers of the atmosphere contain ozone. The lower part of the stratosphere contains the highest concentration, dubbed "the ozone layer". The mesosphere is not dense enough to stop much UV-C from the Sun, so consequently not much ozone is formed there.No.
No it doesn't. The ozone in stratosphere does so.
