The correct Answer is:
To determine the concentration of ozone in the troposphere, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Layers of the Atmosphere**: - The atmosphere is divided into different layers, including the troposphere and stratosphere. The troposphere is the layer closest to the Earth's surface. 2. **Identify the Chemical Formula of Ozone**: - Ozone is a molecule composed of three oxygen atoms, represented by the chemical formula O3. 3. **Recognize the Role of Ozone**: - Ozone plays a crucial role in protecting the Earth from harmful ultraviolet (UV) radiation from the sun. 4. **Know the Concentration of Ozone in the Troposphere**: - The concentration of ozone in the troposphere is typically measured in parts per million (ppm). 5. **Determine the Range of Ozone Concentration**: - According to the information provided, the concentration of ozone in the troposphere ranges from approximately 0.02 to 0.05 ppm. 6. **Select the Correct Answer**: - Based on the range, the highest value mentioned (0.05 ppm) is the correct answer. Therefore, the concentration of ozone in the troposphere is approximately 0.05 ppm. ### Final Answer: The concentration of ozone in the troposphere is **0.05 ppm**. ---

Fill in the blanks : Decrese of the concentreation of ozone in the stratosphere is the cause of formation of………. holes.

Assertion : An equilibrium is established is istablished between generation and destruction of ozone, leading to a steady state concentration of ozone layer in the stratosphere at an altitude of 20-30 km above sea level. Reason : The thickness of the ozone layer is generally larger above the equator and smaller above the poles.

Assertion: Excess of ozone in troposphere called bad ozone while excess in stratosphere is known as "good" ozone. Reason: In troposphere ozone acts as pollutant while in stratosphere it protects from U.V. radiations.
