__________ encompasses the ozone layer.
Show answer Hide answer
Answer: B. Stratosphere
Explanation
The stratosphere contains the highest concentration of atmospheric ozone molecules. Choosing option B correctly identifies the atmospheric layer housing the ozone shield. This layer absorbs harmful ultraviolet radiation protecting life on Earth surface. Earth atmosphere is divided into several vertical layers based on temperature profiles. The stratosphere sits directly above the troposphere where weather events occur. Ozone consists of three oxygen atoms bound together forming a protective planetary blanket.
Environmental science studies stratospheric ozone depletion and international protection treaties. Commercial airplanes often fly in the lower stratosphere to avoid turbulent weather. Meteorology and climatology require deep knowledge of atmospheric layer characteristics. Troposphere is the lowest atmospheric layer where all everyday weather takes place. Mesosphere lies above the stratosphere and experiences extremely cold temperatures. Ionosphere is an upper region ionized by solar radiation facilitating radio communication.
