Diagram showing the five primary layers of the Earth's atmosphere: exosphere, thermosphere, mesosphere, stratosphere, and troposphere. The layers are not to scale. 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.
Consequently, the stratosphere is almost completely free of clouds and other forms of weather. However, polar stratospheric or nacreous clouds are occasionally seen in the lower part of this layer of the atmosphere where the air is coldest. The stratosphere is the highest layer that can be accessed by jet-powered aircraft.
It contains a high concentration of ozone (O 3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. The ozone layer peaks at 8 to 15 parts per million of ozone, [1] while the average ozone concentration in Earth's atmosphere as a whole is about 0.3 parts per million. The ozone layer ...
An atmosphere (from Ancient Greek ἀτμός (atmós) 'vapour, steam' and σφαῖρα (sphaîra) 'sphere') [1] is a layer of gases that envelop an astronomical object, held in place by the gravity of the object. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low.
Black carbon in the atmosphere is like dressing Earth in a black shirt on a sunny day.
The stratosphere receives its warmth from the sun and the ozone layer which absorbs ultraviolet radiation. The next layer, the mesosphere, extends from the stratopause to the mesopause (located at an altitude of 85 km (53 mi)). Temperatures in the mesosphere decrease with altitude, and are the coldest in the Earth's atmosphere. [5]
The Los Angeles Dodgers have agreed to terms with utility player Hyeseong Kim on a three-year contract for $12.5 million with a two-year club option for 2028 and 2029.
