How high does the stratosphere extend approximately?

The stratosphere is a layer of the Earth's atmosphere that is situated above the troposphere and below the mesosphere. It extends from roughly 7 to 30 miles above the Earth's surface. This range is generally accepted in atmospheric science, where the lower boundary is often placed around 7 to 10 miles (11 to 16 kilometers) depending on geographic location and conditions, and it reaches the mesopause at about 30 miles (50 kilometers). The stratosphere is significant because it contains the ozone layer, which plays a crucial role in absorbing the majority of the sun's harmful ultraviolet radiation.

The other ranges provided in the options either fall short or extend beyond the accepted limits of the stratosphere, highlighting the importance of knowing atmospheric layers and their correct altitudes.
