The correct Answer is:
To solve the question of matching the layers of the Earth's atmosphere with their corresponding characteristics, we will analyze each layer and its properties step by step. ### Step-by-Step Solution: 1. **Identify the Layers of the Atmosphere:** - Troposphere - Stratosphere - Mesosphere - Thermosphere 2. **Analyze the Troposphere:** - The troposphere is the lowest layer of the atmosphere and contains most of the atmosphere's mass. It is where weather occurs and is responsible for maintaining the heat balance of the Earth. - **Match:** Troposphere → (iii) Maintenance of heat balance. 3. **Analyze the Stratosphere:** - The stratosphere contains the ozone layer, which protects the Earth from harmful ultraviolet (UV) radiation from the sun. - **Match:** Stratosphere → (i) Prevents UV rays coming to Earth. 4. **Analyze the Mesosphere:** - The mesosphere is located above the stratosphere and is known for its thin air. It is where meteors burn up upon entering the Earth's atmosphere. The thinness of this layer means it does not support sound propagation. - **Match:** Mesosphere → (iv) Non propagation of sound waves. 5. **Analyze the Thermosphere:** - The thermosphere is characterized by high temperatures and is where ionization of gases occurs. This layer is also referred to as the ionosphere due to the presence of ions. - **Match:** Thermosphere → (ii) Ionization of gases. ### Summary of Matches: - (A) Troposphere → (iii) Maintenance of heat balance - (B) Stratosphere → (i) Prevents UV rays coming to Earth - (C) Mesosphere → (iv) Non propagation of sound waves - (D) Thermosphere → (ii) Ionization of gases ### Final Answer: The correct match is: - (A) → (iii) - (B) → (i) - (C) → (iv) - (D) → (ii)
