The terms “stratosphere” and “atmosphere” are often used in discussions about Earth’s environment, but they refer to different concepts. Understanding the distinction between these two can enhance your knowledge of atmospheric science.
Stratosphere
Definition:
The stratosphere is the second layer of Earth’s atmosphere, located between approximately 7 and 50 miles above the Earth’s surface. It contains the ozone layer, which absorbs and scatters ultraviolet solar radiation.
Examples:
The stratosphere plays a crucial role in protecting life on Earth by filtering harmful UV rays from the sun.
Commercial jets typically fly within the lower stratosphere to avoid turbulence found in the troposphere below.
Weather balloons are launched into the stratosphere to collect data about atmospheric conditions.
Atmosphere
Definition:
The atmosphere refers to the entire layer of gases that surround the Earth, extending from the surface up to about 620 miles (1,000 kilometers). It is composed of various gases, primarily nitrogen and oxygen, and is essential for supporting life.
Examples:
The Earth’s atmosphere is vital for maintaining temperature and providing the oxygen necessary for human survival.
Pollution in the atmosphere can lead to serious environmental issues, including climate change and health problems.
Astronomers study the atmosphere of other planets to understand their potential for supporting life.
In summary, while the stratosphere is a specific layer within the broader atmosphere, the atmosphere encompasses all the gases surrounding Earth. Recognizing these differences is important for discussions related to environmental science and meteorology.
