Verified step by step guidance

Understand the structure of Earth's atmosphere, which is divided into several layers: Troposphere, Stratosphere, Mesosphere, and Thermosphere.

Recognize that the Stratosphere is the second layer of the atmosphere, located above the Troposphere and below the Mesosphere.

Learn that the Stratosphere contains the ozone layer, which is crucial for absorbing the majority of the Sun's harmful ultraviolet (UV) radiation.

Identify that the absorption of UV light by the ozone layer in the Stratosphere protects living organisms on Earth from potential damage caused by UV radiation.

Conclude that the Stratosphere is the layer of the atmosphere that absorbs significant amounts of ultraviolet light, making it essential for life on Earth.
