What is the correct sequence of layers of the atmosphere from innermost to outermost?

The correct sequence of layers of the atmosphere from innermost to outermost is the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The troposphere is where weather occurs and contains most of the atmosphere's mass. Above it, the stratosphere houses the ozone layer, followed by the mesosphere, where temperatures decrease with altitude. The thermosphere is characterized by high temperatures and low density, and the exosphere is the outermost layer, where the atmosphere gradually fades into space.
