Correct Answer:
Option B —
Stratosphere
The atmosphere is divided into layers based on temperature and altitude. The stratosphere sits directly above the troposphere (the layer where we live and breathe).
The Ozone Layer: About 90% of the Earth's ozone is concentrated in the lower portion of the stratosphere, typically between 15 to 35 kilometers above the Earth's surface.
The Function: This layer acts as a "shield," absorbing about 97% to 99% of the sun's medium-frequency ultraviolet (UV) light, which would otherwise damage living organisms on the surface.
