Multiple choice

How does granite quarrying impact biodiversity?

  1. Enhances habitat diversity

  2. Promotes species migration

  3. Reduces habitat fragmentation

  4. Disrupts ecological balance
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Granite quarrying can disrupt the ecological balance by fragmenting habitats, displacing wildlife, and altering ecosystem dynamics. The removal of vegetation and the creation of barren landscapes can lead to a decline in biodiversity and ecosystem services.
