Ozone layer of atmosphere protects the living organisms from

Options

A. high temperature
B. harmful radiations of sun
C. hail and snow
D. water pollution

Explanation

**Step-by-Step Solution:**

1. **Understanding the Ozone Layer**: The ozone layer is a region of Earth's stratosphere that contains a high concentration of ozone (O3) molecules. It is located approximately 10 to 30 miles above the Earth's surface.

2. **Function of the Ozone Layer**: The primary function of the ozone layer is to absorb the majority of the sun's harmful ultraviolet (UV) radiation. This absorption is crucial for protecting living organisms on Earth.

3. **Analyzing the Options**:
- **Option 1: High Temperature**: The ozone layer does not protect against high temperatures. Instead, it helps to regulate temperatures indirectly by blocking UV radiation. This option is incorrect.
- **Option 2: Harmful Radiation of the Sun**: This option is correct. The ozone layer protects living organisms from harmful UV radiation emitted by the sun, which can cause skin cancer, cataracts, and other health issues.
- **Option 3: Hail and Snow**: The ozone layer does not provide protection against weather phenomena like hail and snow. This option is incorrect.
- **Option 4: Water Pollution**: The ozone layer does not protect against water pollution. This option is also incorrect.

4. **Conclusion**: Based on the analysis of the options, the correct answer is that the ozone layer protects living organisms from harmful radiation of the sun, specifically UV radiation.

**Final Answer**: The ozone layer of the atmosphere protects living organisms from harmful radiation of the sun (UV radiation).
