HELLO!
Here are some natural disasters that affects the corals.
-A drop in sea level exposes corals.
-A rise in sea level decreases the amount of available sunlight and may inhibit growth. Added emissions of carbon dioxide and other trace gases (called greenhouse gases) into our atmosphere may be causing a gradual warming of our planet. This warming could cause the polar ice caps to melt, thereby raising sea level.
-Rises in sea level can also release nutrients trapped in soil.
-Coral diseases can wipe out entire strands of coral reefs. Diseases may be connected to the sea level rise and nutrient level increase.
Coral bleaching occurs when coral expels its symbiotic zooxanthellae. As a result, the coral loses its coloration. Without zooxanthellae, the coral polyps have little energy available for growth or reproduction. Scientists aren't sure why bleaching occurs. Hypotheses include elevated water temperatures, ultraviolet radiation, and diseases or viruses affecting the zooxanthellae.
-Major tropical storms can strip corals from miles of reef habitat.
