The correct sequence of layers as we move from the Earth`s surface upwards is option 2: Troposphere, Stratosphere, Mesosphere, Thermosphere.

The troposphere is the lowest layer of the Earth`s atmosphere, extending from the surface up to an average height of about 8-15 kilometers. It is where weather phenomena occur and contains most of the Earth`s air mass. As we move higher, we enter the stratosphere.

The stratosphere is the second layer of the atmosphere, extending from the top of the troposphere to an altitude of about 50 kilometers. It contains the ozone layer, which absorbs harmful ultraviolet radiation from the Sun. Beyond the stratosphere lies the mesosphere.

The mesosphere is the third layer of the atmosphere, extending from about 50 to 85 kilometers above the Earth`s surface. It is the layer where meteors burn up upon entering the atmosphere. Lastly, we have the thermosphere.

The thermosphere is the outermost layer of the Earth`s atmosphere, starting at about 85 kilometers and extending beyond the Kármán line, which is about 100 kilometers above the Earth`s surface. It is characterized by high temperatures and the presence of ionized gases.

Therefore, option 2
