Final answer:
The ozone layer is located in the B. stratosphere, which is the second layer of the Earth's atmosphere, sitting just above the troposphere.
Step-by-step explanation:
The ozone layer is a critical part of Earth's atmosphere that absorbs most of the sun's harmful ultraviolet rays. Specifically, the ozone layer is found within the stratosphere, which is one of the five layers that make up the Earth's atmosphere. This vital layer contains a high concentration of ozone molecules, which are instrumental in protecting life on Earth from excessive UV radiation. The stratosphere extends from about six miles (12 kilometers) above the Earth's surface to around 31 miles (50 kilometers) high, making it the second-lowest layer of the atmosphere, just above the troposphere.
The ozone layer is found in the stratosphere, which is the second lowest level of Earth's atmosphere. The stratosphere extends from 12 to 50 kilometers above sea level. It is in this layer that the majority of the ozone in the atmosphere is concentrated. The ozone layer plays a crucial role in protecting the Earth from harmful ultraviolet B rays, which can cause skin cancer and genetic damage.
