What are the four layers of the atmosphere from lowest to highest?

The atmospheric layers, starting from the surface of the Earth and moving upwards, are organized in a specific order based on temperature gradients and altitude. The troposphere is the lowest layer, where we experience weather and most of the atmosphere's mass. As altitude increases, the stratosphere follows, which contains the ozone layer that absorbs and scatters ultraviolet solar radiation. Above the stratosphere is the mesosphere, where temperatures again decrease with altitude. Finally, the thermosphere is the highest layer, characterized by rising temperatures due to the absorption of high-energy solar radiation.

The correct sequence of these layers from lowest to highest is troposphere, stratosphere, mesosphere, and thermosphere, making the choice accurate. Understanding this order is crucial as each layer plays a different role in environmental and weather-related phenomena.
