Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
coral bleaching is when algae that live inside die due to warming water? true or false?
A
false
B
true
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The leading cause of coral bleaching is climate change. A warming planet means a warming ocean, and a change in water temperature-as little as 2 degrees Fahrenheit-can cause coral to drive out algae. Coral may bleach for other reasons, like extremely low tides, pollution, or too much sunlight.

Detailed explanation-2: -Warmer water temperatures can result in coral bleaching. When water is too warm, corals will expel the algae (zooxanthellae) living in their tissues causing the coral to turn completely white. This is called coral bleaching.

Detailed explanation-3: -Warm water can contribute to a potentially fatal process known as coral bleaching, in which reef-building corals eject the algae living inside their tissues. Corals bleach when ocean waters warm just 1-2°C (2-4°F) above normal summertime temperatures.

Detailed explanation-4: -Reef-building corals cannot tolerate water temperatures below 64° Fahrenheit (18° Celsius). Many grow optimally in water temperatures between 73° and 84° Fahrenheit (23°–29°Celsius), but some can tolerate temperatures as high as 104° Fahrenheit (40° Celsius) for short periods.
