Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Coral bleaching is caused by a rise in water temperature. When the water temperature gets too high, the coral expels the symbiotic algae that live in its tissues. This causes the coral to turn white and become more susceptible to disease and death.

Multiple choice

What is the main source of pollution that is harming coral reefs?

  1. Sewage

  2. Fertilizers

  3. Oil spills

  4. Plastic pollution
