above the troposphere lies the stratosphere, where the ozone layer resides. the stratosphere is less dense than the troposphere and plays a crucial role doing what? shielding the earth from uv radiation generating weather patterns providing oxygen for respiration
Answer
Brief Explanations:
The ozone layer in the stratosphere absorbs harmful ultraviolet (UV) radiation from the sun. Weather patterns are mainly generated in the troposphere. Oxygen for respiration is mostly in the troposphere and produced by plants (not the stratosphere's main role).
Answer:
shielding the Earth from UV radiation
