STRATOSPHERE
Mesosphere.

The second layer of Earth's atmosphere is the stratosphere. It is located above the troposphere and extends from about 10 to 50 kilometers above the Earth's surface. The stratosphere contains the ozone layer, which absorbs and scatters the majority of the sun's ultraviolet radiation, making it crucial for protecting life on Earth.
OZONE Layer
The top layer of Earth's atmosphere is called the exosphere. It is the outermost layer where the atmosphere transitions into space. The exosphere is very thin and composed mostly of low-density gases.
It's called lithosphere as I remember in science.
The third layer of the Earth's atmosphere is called the mesosphere. It is located above the stratosphere and below the thermosphere, with temperatures decreasing with height in this layer. The mesosphere is where most meteoroids burn up upon entering the Earth's atmosphere.
There is a region in atmosphere containing ozone. It is called ozone layer.
The ozone layer is contained in the second layer of Earth's atmosphere, called the Stratosphere.
The lowest layer of Earth's atmosphere is called the troposphere. It is where the majority of Earth's weather occurs and contains around 75% of the atmosphere's mass. Temperature decreases with altitude in the troposphere.
