Layers of the Atmosphere
The troposphere reaches from the Earth’s atmosphere to a height of 8 to 14.5 kilometres (5 to 9 miles). This is the most dense component of the atmosphere. Almost every kind of weather can be found in this region.
The stratosphere rises to a height of 50 kilometres (31 miles) above the troposphere. This membrane contains the ozone layer, which absorbs and scatters solar ultraviolet radiation.
The mesosphere is a layer of the atmosphere that begins well above the stratosphere and reaches a height of 85 kilometres (53 miles). In this plate, meteors flame up.
This layer stretches from about 31 miles (50 kilometres) above the Earth’s surface to 53 miles (80 kilometres) (85 km). As one descends, the atoms, including the oxygen molecules, become denser. As a result, as one descends, temperatures rise, reaching around 5°F (-15°C) at the bottom of this plate.
The bubbles in the mesosphere have thickened to the point that meteors hurtling into the atmosphere can now be slowed before burning up and leaving fire tracks in the night sky. The stratosphere (next layer down) and the mesosphere (next layer up) are both known to be part of the middle atmosphere. The stratopause is the transitional boundary between the mesosphere and the stratosphere.
The thermosphere begins just above the mesosphere and rises to a height of 600 kilometres (372 miles). This layer is where the aurora and satellites appear.
The thermosphere is located between 53 miles (85 kilometres) and 375 miles (600 kilometres). The upper atmosphere is the name given to this sheet. As one descends into the surface, the gases of the thermosphere get denser while also becoming relatively light.
The ionosphere is a dense cloud of electrons and ionised atoms and molecules that extends from the earth to the edge of space at a distance of 965 kilometres (600 miles), overlapping the mesosphere and thermosphere. This complex area expands and contracts in response to solar conditions, and is further divided into sub-regions D, E, and F, depending on the wavelength of solar radiation absorbed. The ionosphere is an important element in the Sun-Earth contact chain. This area is what gives radio its communicative power.
