Final answer:
The layers of the Earth's atmosphere are primarily characterized by changes in air pressure, with distinct features in each layer such as temperature and gas concentrations, including the troposphere and stratosphere.
Step-by-step explanation:
The layers of the atmosphere are characterized by changes in air pressure, among other variables. The Earth's atmosphere is divided into five main layers: the troposphere, the stratosphere, the mesosphere, the thermosphere, and the exosphere. The troposphere is the layer closest to Earth's surface, where most of the weather and wind patterns occur due to the heating of the
As altitude increases, air pressure decreases, and each atmospheric layer exhibits distinct characteristics regarding temperature and gas composition. The most abundant gases are nitrogen (N2) and oxygen (O2), with minor concentrations of water vapor, carbon dioxide (CO2), and other trace gases. The composition and circulation of the atmosphere are essential to Earth's climate and have a significant impact on weather patterns.
