Multiple choice

Which of the following is NOT a potential consequence of volcanic eruptions on human health?

  1. Respiratory problems due to ash inhalation.

  2. Cardiovascular issues caused by sulfur dioxide exposure.

  3. Increased risk of skin cancer from UV radiation.

  4. Enhanced crop yields due to volcanic ash fertilization.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

While volcanic eruptions can have negative impacts on agriculture, such as crop damage due to ash fall, they can also lead to increased soil fertility in some cases. Volcanic ash can provide essential nutrients for plant growth, potentially enhancing crop yields in certain regions.

  1. Noise pollution

  2. Excessive noise

  3. Hazardous noise

  4. Dangerous noise
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Hazardous noise refers to noise levels that can cause permanent hearing loss or other health problems, such as sleep disturbance and cardiovascular issues.

Multiple choice

Which of the following is NOT a potential health effect of noise pollution?

  1. Hearing loss

  2. Sleep disturbance

  3. Cardiovascular disease

  4. Improved cognitive function
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Noise pollution is typically associated with negative health effects, such as hearing loss, sleep disturbance, and cardiovascular disease. Improved cognitive function is not a known health benefit of noise pollution.
