The stratosphere (/ ˈ s t r æ t ə ˌ s f ɪər,-t oʊ-/) is the second-lowest layer of the atmosphere of Earth, located above the troposphere and below the mesosphere. [ 2 ] [ 3 ] The stratosphere is composed of stratified temperature zones, with the warmer layers of air located higher (closer to outer space ) and the cooler layers lower ...
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.
The stratosphere is very dry air, containing little water vapor. Because of this, few clouds are found in this layer. Polar stratospheric clouds (PSCs) are the exception. PSCs (also called nacreous clouds) appear in the lower stratosphere near the poles in winter.
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.
11 paź 2024 · The stratosphere is a layer of Earth’s atmosphere. The stratosphere is located above the troposphere and below the mesosphere.
19 paź 2024 · Stratosphere, layer of Earth’s atmosphere lying between the troposphere and the mesosphere. The lower portion of the stratosphere is nearly isothermal (a layer of constant temperature), whereas temperatures in its upper levels increase with altitude.
25 cze 2024 · Earth’s atmosphere has a layered structure. From the ground toward the sky, the layers are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Another layer, called the ionosphere, extends from the mesosphere to the exosphere. Beyond the exosphere is outer space.
