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

The Earth’s atmosphere is organized into distinct layers based on temperature changes and chemical properties. Starting from the surface, the troposphere is the first layer, containing most of the air mass and weather. Above the tropopause is the stratosphere, home to the ozone layer. The mesosphere follows, where temperatures reach their lowest points. Finally, the ionosphere, often considered part of the thermosphere, contains charged particles that reflect radio waves. This vertical arrangement is crucial for understanding how energy moves through the atmosphere and how different physical processes, from cloud formation to satellite orbits, are managed naturally.
