What is the correct sequence of the different layers of the atmosphere from the Earth’s surface upwards?
The correct sequence from the surface upward is the Troposphere, Stratosphere, Mesosphere and Ionosphere. The troposphere is the lowest layer where weather occurs. Above it lies the stratosphere, followed by the mesosphere, where temperatures drop significantly. Finally, the ionosphere is located in the upper reaches, where solar radiation ionizes gas particles. This order defines the vertical structure of air. ANSWER: (B) Troposphere, Stratosphere, Mesosphere, Ionosphere
