Which event does the ocean conveyor belt virtual lab predict will occur when earths temperature warms to 15.75*c? a. the amount of earth covered by ice will increase to 25 percent b. average sea level will decrease by 500 millimeters c. the rate of alpine glacier melting will decrease d. much of the east coast will flood

The correct answer is option D, that is, much of the east coast will flood.  

The thermohaline circulation of seawater or the ocean circulation conveyor belt circulates massive water currents from northern to southern oceans and back again. The water from tropical Atlantic is warm and moves towards the poles providing heat to the atmosphere that declines the temperature at some extent in the higher altitudes.  

The warm water on discharging heat becomes denser and sinks down. This closed circulation loop makes the cold water move towards the tropical area at the deeper levels. The Atlantic functions as an engine for the whole planet's conveyor belt of the ocean current, the cold water that is sinking up in the North Atlantic mediates current in the Pacific ocean as well.
