Why is it not safe to swim in a lake during a thunderstorm?

Options

A. Because water conducts electricity
B. Because swimming pool conducts electricity
C. Both A and B
D. None of these

Explanation

### Step-by-Step Solution:

1. **Understanding Thunderstorms**: During a thunderstorm, atmospheric conditions lead to the formation of clouds that can generate lightning.

**Hint**: Think about what happens in the atmosphere during a storm.

2. **Formation of Charges**: In a thunderstorm, clouds develop a separation of electric charges. Typically, the top of the cloud becomes positively charged while the bottom becomes negatively charged.

**Hint**: Consider how charges behave in clouds and their interaction with the ground.

3. **Lightning Generation**: The difference in charge between the cloud and the ground can lead to the discharge of electricity in the form of lightning. This discharge can occur when the charge difference becomes too great.

**Hint**: Recall how lightning is formed due to electrical imbalances.

4. **Water as a Conductor**: Water, especially in lakes, is a good conductor of electricity due to the presence of dissolved ions. This means that if lightning strikes the water, the electrical current can easily spread throughout the water.

**Hint**: Think about the properties of water and how they relate to electricity.

5. **Risk of Electric Shock**: If a person is swimming in a lake during a thunderstorm and lightning strikes the water, the electrical current can travel through the water. This poses a serious risk of electric shock to anyone in or near the water.

**Hint**: Consider the effects of electricity on the human body and how it travels through different mediums.

6. **Conclusion**: Therefore, it is not safe to swim in a lake during a thunderstorm because of the risk of lightning strikes and the conductive nature of water, which can lead to severe injuries or fatalities.

**Hint**: Summarize the main reasons why swimming during a thunderstorm is dangerous.
