GEOLOGY

Detailed explanation-1: -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. When a coral bleaches, it is not dead. Corals can survive a bleaching event, but they are under more stress and are subject to mortality.

Detailed explanation-2: -Climate change is warming our oceans and that shift is impacting vibrant ecosystems. Coral reefs are bright and colorful because of the algae that live in them. When water temperatures rise too high, the algae are forced out of the coral, causing the reefs to lose color and potentially die.

Detailed explanation-3: -Coral bleaching matters because once these corals die, reefs rarely come back. With few corals surviving, they struggle to reproduce, and entire reef ecosystems, on which people and wildlife depend, deteriorate.

Detailed explanation-4: -When corals overheat, they react to the stress by expelling their algae, which results in coral bleaching. Bleaching leaves corals vulnerable to disease, stunts their growth, affects their reproduction, and can impact other species that depend on the coral communities. Severe bleaching kills them.

Detailed explanation-5: -The leading cause of coral bleaching is rising water temperatures.
