What would happen to a coral reef if sea levels suddenly rose? ?

It would be destroyed; coral is a sensitive organism that takes just the right amount of light and warmth to thrive. If the sea levels rise, the shallow-water fish that fertilize the soil and eat the pests would be forced higher than the coral. Deeper water means less light, and in turn, less heat. A drastic water level rise would take away every parameter that coral needs to live, so it would just die, leaving only the already shed skeleton behind.

They would die.

Explanation: The sudden rise in the sea level will make the coral die. This is because the coral would not be able to survive in the stress conditions.

The coral have algae residing inside them and they perform photosynthesis. If the sudden level will rise then the algae will not get adequate amount of sunlight to perform photosynthesis.

So, the corals will die if the sea level will rise suddenly.

Physical Properties: Physical properties can be observed or measured without changing the composition of matter. Physical properties are used to observe and describe matter. so physical changes are the change in temperature of the land and the evaporation of water and change humidity of the air. chemical change is the ripening of the orange
