Ozone layer is important as it

Options

A. Reduces light reflection
B. Provides oxygen to jet fluers
C. Absorbs extra light-rays
D. Filters out ultra-violet radiations.

Answer

**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) gas. 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 is crucial because UV radiation can cause various health issues in humans, such as skin cancer, and can also harm animals and plants.

3. **Importance of Filtering UV Radiation**: By filtering out UV radiation, the ozone layer protects living organisms on Earth. Without this protective layer, the intensity of UV rays reaching the surface would increase significantly, leading to detrimental effects on ecosystems and human health.

4. **Conclusion**: Therefore, the ozone layer is important because it filters out ultraviolet radiation, making it essential for the protection of life on Earth.

**Final Answer**: The ozone layer is important as it filters out ultraviolet radiation.
