Question

How does acid rain impact the environment?

1. It leads to a decrease in carbon dioxide levels.
2. It increases soil fertility and agricultural productivity.
3. It damages aquatic ecosystems, forests, and buildings.
4. It accelerates the process of desertification.

Options

• 1. & 2.

• 3. & 4.

• Only 1.

• Only 3.

Answer 1

Only 3.

Explanation:

Acid rain has a negative influence on the ecosystem because it lowers the pH of water bodies, killing fish and other aquatic life, and leaches important nutrients from the soil, degrading trees. It also reacts chemically with architectural materials such as limestone and marble, resulting in rapid weathering and structural damage to historical monuments and modern infrastructure.
