{'stratosphere': [1, 0, 1, 0], 'atmospheric layers': [1, 0, 0, 0], 'isoclinal layer': [0, 0, 1, 0], 'troposphere': [6, 1, 1, 1], 'stratification': [0, 0, 1, 0], 'top layers': [0, 0, 1, 0], 'cirrus clouds': [0, 0, 1, 0], 'cloudiness': [0, 0, 1, 0]}
Option 1 states that all storms and cloudiness are restricted to the stratosphere. This is incorrect. Storms and cloudiness can occur in different layers of the atmosphere, including the troposphere and stratosphere.
Option 2 states that cirrus clouds are formed in the top layers of the troposphere. This is correct. Cirrus clouds are thin and wispy clouds that form at high altitudes in the troposphere.
Option 3 states that the stratosphere is also an `isoclinal layer`. This is incorrect. The stratosphere is not an isoclinal layer. An isoclinal layer refers to a layer of the atmosphere where the inclination of the magnetic field lines is the same.
Therefore, the correct answer is Option 3, which states that statements 2 and 3 are correct.
