While the stratosphere is dry, additional water vapor is produced in situ by the photochemical oxidation of methane (CH 4). The HO 2 radical produced by the reaction of OH with O 3 is recycled to OH by reaction with oxygen atoms or ozone.
20 sie 2024 · The stratosphere extends from 4 -12 miles (6-20 km) above the Earth's surface to around 31 miles (50 km). This layer holds 19 percent of the atmosphere's gases but very little water vapor. In this region, the temperature increases with height.
Between 85 and 90% of all the ozone in the atmosphere is found in the stratosphere. Ozone is formed when sunlight breaks down molecular oxygen (O 2) in the stratosphere into oxygen atoms (O). The highly reactive oxygen atoms then react with more molecular oxygen to form ozone (O 3).
1 gru 2020 · Stratosphere: 14 to 64 km (9 to about 31 miles) Unlike the troposphere, temperatures in this layer increase with elevation. The stratosphere is very dry, so clouds rarely form here. It also contains most of the atmosphere’s ozone, triplet molecules made from three oxygen atoms. At this elevation, ozone protects life on Earth from the sun’s ...
The lower boundary of the stratosphere is called the tropopause; the upper boundary is called the stratopause. Ozone , a type of oxygen molecule that is relatively abundant in the stratosphere, heats this layer as it absorbs energy from incoming ultraviolet radiation from the Sun. Temperatures rise as one moves upward through the stratosphere.
The stratosphere extends from the top of the troposphere to about 50 km (31 miles) above the ground. The infamous ozone layer is found within the stratosphere. Ozone molecules in this layer absorb high-energy ultraviolet (UV) light from the Sun, converting the UV energy into heat.
25 cze 2024 · The stratosphere is crucial to life on Earth because it contains small amounts of ozone, a form of oxygen that prevents harmful UV rays from reaching Earth. The region within the stratosphere where this thin shell of ozone is found is called the ozone layer .
