Final answer:
The ozone layer is found in the stratosphere, which is the layer of Earth's atmosphere just above the troposphere and below the mesosphere.
Step-by-step explanation:
Location of the Ozone Layer
The ozone layer is located in the stratosphere, which is the second layer of Earth's atmosphere, sitting above the troposphere and below the mesosphere. The stratosphere extends roughly from 12 kilometers (7.5 miles) to 50 kilometers (31 miles) above Earth's surface. Within the stratosphere, the concentration of ozone is highest, forming what is known as the ozone layer. This layer is critical for life on Earth as it absorbs the majority of the sun's harmful ultraviolet B rays, which are known to cause skin cancer and genetic damage.
The correct answer to the question "Which layer of Earth's atmosphere is home to the ozone layer?" is b. Stratosphere.
