At what altitude does the ozone layer extend above the Earth?

The ozone layer is primarily located in the stratosphere, which extends from about 7 to 30 miles above the Earth's surface. This layer plays a critical role in protecting life on Earth by absorbing the majority of the sun's harmful ultraviolet radiation. The correct choice reflects the altitude range that encompasses where ozone concentration is most significant, allowing for effective filtration of UV rays. Understanding the importance of the ozone layer and its location helps illustrate its role in environmental protection and human health.
