The important role that the stratosphere plays is primarily related to the ozone layer and protection from harmful ultraviolet (UV) rays. Here's why:
1. Ozone Layer: The stratosphere contains the ozone layer, which helps to absorb and filter out a significant portion of the Sun's harmful ultraviolet radiation.
2. UV Ray Absorption: By absorbing most of the harmful ultraviolet rays from the Sun, the ozone layer shields living organisms on Earth from the damaging effects of excessive UV exposure. This protection is crucial for preventing health issues such as skin cancer and cataracts.
3. Weather and Air Pressure: While the stratosphere does not play a direct role in weather patterns (as they occur in the troposphere), its relatively low air pressure contributes to the separation of layers in the atmosphere, each with its distinct characteristics.
In summary, the stratosphere's significance lies in hosting the ozone layer, which acts as a shield against harmful UV radiation, safeguarding life on Earth.
