2024年8月20日 · Between about 53 miles (85 km) and 375 miles (600 km) lies the thermosphere, known as the upper atmosphere. While still extremely thin, the gases of the thermosphere become increasingly denser as one descends toward the Earth.

The stratosphere (/ ˈstrætəˌsfɪər, - toʊ -/) 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 (closer to the planetary ...

The stratosphere is a layer of Earth's atmosphere. It is the second layer of the atmosphere as you go upward. The troposphere, the lowest layer, is right below the stratosphere. The next higher layer above the stratosphere is the mesosphere.

2013年1月25日 · The Earth’s atmosphere has four primary layers: the troposphere, stratosphere, mesosphere, and thermosphere. These layers protect our planet by absorbing harmful radiation.

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.

2023年10月6日 · Scientists divide the atmosphere into 5 different layers based on factors like air pressure and density. The names of these layers, in order of lowest to highest, are: Troposphere; Stratosphere; Mesosphere; Thermosphere; Exosphere

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.

2023年11月30日 · The stratosphere is the second-lowest level in Earth's atmosphere. It's a bastion of ozone gas and rapid winds, where clouds are scarce — but life endures. Sometimes referred to as "near space," it's where companies and countries are in a race to send new technology that can collect data and intelligence, snap high-resolution images, and even ...

The upper stratosphere is defined as that region of the atmosphere bounded beneath by the stratonull surface and above by the stratopause. The stratonull is located roughly at the 24-km altitude level and the stratopause is nominally located at the 50-km level.

The stratosphere is the second atmospheric layer from the ground level. It sits above the troposphere and is directly below the mesosphere. The stratosphere is bounded by the tropopause and stratopause. It’s characterized by a highly stable temperature gradient that cools from top to bottom.
