\nThe correct option is B, Troposphere, Stratosphere, Mesosphere, Thermosphere.
\n<\/section>\n
\nThe Earth’s atmosphere is divided into several layers based on temperature profiles and composition as we move upwards from the surface. The principal layers, in order from the Earth’s surface outwards, are:
\n1. **Troposphere:** The lowest layer, where most weather occurs. Temperature generally decreases with altitude.
\n2. **Stratosphere:** Above the troposphere, contains the ozone layer. Temperature increases with altitude due to ozone absorption of UV radiation.
\n3. **Mesosphere:** Above the stratosphere. Temperature decreases with altitude; it is the coldest layer. Most meteors burn up here.
\n4. **Thermosphere:** Above the mesosphere. Temperature increases sharply with altitude due to absorption of high-energy solar radiation by sparse gas molecules. The International Space Station orbits here.
\nAbove the thermosphere is the Exosphere, transitioning into outer space.
\n<\/section>\n
\nThe given options only list the first four main layers. The correct sequence starting from the surface is Troposphere, followed by Stratosphere, then Mesosphere, and finally Thermosphere among the layers listed.
