Multiple choice

What is the term used to describe the process by which acid rain damages human health?

  1. Acidification

  2. Corrosion

  3. Dieback

  4. Leaching
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Acid rain can cause corrosion of buildings and structures, particularly those made of limestone, marble, and sandstone. The acidic components of acid rain react with these materials, causing them to deteriorate and weaken over time.

Multiple choice

What is the term used to describe the process by which toxic substances accumulate in the tissues of organisms as they move up the food chain?

  1. Biomagnification

  2. Bioaccumulation

  3. Eutrophication

  4. Salinization
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Biomagnification is the process by which toxic substances, such as heavy metals and pesticides, accumulate in the tissues of organisms as they move up the food chain. This can lead to high concentrations of these substances in top predators, posing a risk to their health and the health of humans who consume them.
