{'thermosphere': [0, 0, 0, 4], 'troposphere': [6, 1, 1, 1], 'stratosphere': [1, 0, 1, 0], 'layers': [5, 2, 1, 10], 'atmosphere': [1, 1, 4, 7], 'altitude': [3, 0, 9, 13], 'mesosphere': [2, 0, 0, 0]}

The correct sequence of the layers of the atmosphere with increasing altitude from the Earth`s surface is option 1: 1-2-3-4.

1. Troposphere: This is the lowest layer of the atmosphere and is closest to the Earth`s surface. It extends to an average altitude of about 12 kilometers (7.5 miles) near the poles and 18 kilometers (11 miles) near the equator.

2. Stratosphere: Above the troposphere lies the stratosphere. It extends from the top of the troposphere to about 50 kilometers (31 miles) above the Earth`s surface. The ozone layer is located in this layer, which absorbs much of the Sun`s harmful ultraviolet (UV) radiation.

3. Mesosphere: The mesosphere is above the stratosphere and extends to about 85 kilometers (53 miles) above the Earth`s surface. This is the layer where meteors burn up upon entering the Earth`s atmosphere.

4. Thermosphere: The thermosphere is the outermost layer of the atmosphere and extends from about 85 kilometers (53 miles) to over 600 kilometers (373 miles) above the Earth`s surface. It is characterized by high temperatures due to the absorption of high-energy solar radiation
