The ozone layer, which plays a crucial role in absorbing harmful ultraviolet (UV) radiation from the Sun, is primarily located in the stratosphere. This layer of the atmosphere is found above the troposphere and extends to about 50 kilometers above the Earth’s surface.
– The atmosphere is divided into several layers: Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere.
– Each layer has distinct characteristics regarding temperature profile and composition.
The troposphere is the lowest layer where most weather occurs. The mesosphere is above the stratosphere, and temperature decreases with height. The ionosphere is part of the thermosphere and upper mesosphere, characterized by ionized gases important for radio communication.
