Pollution and Human Impact Questions

Multiple choice

Which of the following is a potential consequence of potassium fertilizer leaching?

  1. Soil salinization

  2. Groundwater contamination

  3. Air pollution

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

Potassium fertilizer leaching can lead to groundwater contamination, as excess potassium can be dissolved in water and carried deep into the soil profile, potentially affecting drinking water sources.

Multiple choice

What is the primary environmental concern associated with the excessive use of potassium fertilizers in agriculture?

  1. Air pollution

  2. Water pollution

  3. Soil contamination

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

The excessive use of potassium fertilizers in agriculture is primarily associated with water pollution, as excess potassium can be leached into groundwater and surface water, leading to eutrophication and algal blooms.

Multiple choice

What is the primary cause of coral bleaching?

  1. Increased water temperature

  2. Ocean acidification

  3. Pollution

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