Approximately how far above Earth is the ozone layer located?

The ozone layer is situated within the stratosphere, typically between about 10 to 30 miles above Earth's surface. The most concentrated region of ozone, where the protective layer is strongest, is generally found at around 20 miles. This part of the atmosphere plays a crucial role in absorbing the majority of the sun's harmful ultraviolet (UV) radiation, thereby protecting life on Earth.

The ozone layer is vital for maintaining ecological balance and human health. Its placement at approximately 20 miles up is significant because it allows for effective filtration of UV rays while still being close enough to participate in atmospheric processes that influence weather patterns and climate. This altitude is a critical component of the Earth's atmospheric structure, making it essential for maintaining the conditions necessary for life.
