The depletion of the ozone layer causes

Options

A. Global warming
B. Earthquakes
C. Acid rain
D. Increased UV radiations

Explanation

### Step-by-Step Solution:

1. **Understanding Ozone Layer**: The ozone layer is a region of Earth's stratosphere that contains a high concentration of ozone (O3) molecules. It plays a crucial role in protecting life on Earth by absorbing the majority of the sun's harmful ultraviolet (UV) radiation.

2. **Identifying the Effects of Ozone Depletion**: When the ozone layer is depleted, it leads to an increase in the amount of UV radiation that reaches the Earth's surface. This can have several harmful effects on both the environment and human health.

3. **Analyzing the Options**:
- **Global Warming**: While the ozone layer does play a role in climate regulation, its depletion primarily leads to increased UV radiation rather than directly causing global warming.
- **Earthquakes**: There is no direct correlation between ozone layer depletion and earthquakes.
- **Acid Rain**: Acid rain is primarily caused by the emission of sulfur dioxide and nitrogen oxides, not by ozone depletion.
- **Increased UV Radiation**: This is the most direct consequence of ozone layer depletion, as the layer's primary function is to filter out harmful UV rays.

4. **Conclusion**: The correct answer is that the depletion of the ozone layer causes increased UV radiation, which can lead to various health issues such as skin cancer, cataracts, and other environmental impacts.

### Final Answer:
The depletion of the ozone layer causes increased UV radiation.
