Consider the following statements on atmosphere:1. Important feature ...
- Troposphere: The most important layer of the atmosphere with an average height of 13 km. It contains the air that we breathe. Almost all the weather phenomena (rainfall, fog and hailstorm) happen in this layer.
- Stratosphere: Lies above the troposphere, with height extending up to 50 km. This layer is also associated with weather phenomenon. This layer is free from clouds and most ideal for flying aeroplanes. The important feature of this layer is the presence of a layer of ozone gas. We have just learnt its protective action against the harmful effect of the Sun’s rays.
- Mesosphere: Third layer that lies above the stratosphere, with a height that extends up to 80 km. Meteorites bum upon entering from the space.

Consider the following statements on atmosphere:1. Important feature ...
Explanation:
The given statements are related to different layers of the atmosphere and their characteristics. Let's analyze each statement:
1. Important feature of the stratosphere is that it contains a layer of ozone gas.
The stratosphere is the second layer of the Earth's atmosphere, located above the troposphere. It extends from about 10 to 50 kilometers above the Earth's surface. One of the important features of the stratosphere is the presence of the ozone layer. The ozone layer is a layer of ozone gas (O3) that plays a crucial role in absorbing most of the Sun's ultraviolet (UV) radiation. This absorption of UV radiation by ozone protects life on Earth from the harmful effects of excessive UV exposure. Therefore, statement 1 is correct.
2. Meteorites burn up in the mesosphere on entering from space.
The mesosphere is the third layer of the Earth's atmosphere, located above the stratosphere. It extends from about 50 to 85 kilometers above the Earth's surface. The mesosphere is characterized by low air pressure and very cold temperatures. When meteoroids (small solid objects from space) enter the Earth's atmosphere, they experience intense heating due to the friction with air molecules. This heating causes them to burn up and disintegrate. The majority of meteoroids burn up in the mesosphere before reaching the Earth's surface. Therefore, statement 2 is correct.
3. Almost all the weather phenomena like rainfall, fog, and hailstorms occur in the troposphere.
The troposphere is the lowest layer of the Earth's atmosphere, extending from the Earth's surface up to about 10 kilometers. It is where weather phenomena occur. The troposphere is characterized by vertical air circulation, where warm air rises and cool air sinks. This circulation creates weather patterns such as rainfall, fog, and hailstorms. Therefore, statement 3 is correct.
Conclusion:
All the given statements are correct. The important feature of the stratosphere is the presence of the ozone layer, meteorites burn up in the mesosphere, and almost all weather phenomena occur in the troposphere. Therefore, the correct answer is option D, "All of the above."
