Convection currents occur in the MANTLE. The mantle is the second layer of the earth after the crust. The mantle is approximately 2900 km thick. Convection currents are triggered or fueled by the heat from the Earth's core.
The part of the mantle closest to the core gets heated. It then becomes less dense than the layers above so it rises. When this rising plume interacts with the crust it cools and becomes more dense than the layers below and so it sinks and this circular motion continues to form convection currents.
There's actually an entire documentary made about this certain fish, its name is Parrot Fish.
The reason for its name is because it has a beak, which it uses to bite and eat through coral.
And at the end of the day, when the fishes poop, it turns into sand.
For example, one 2010 study in Marine Biology found that large parrotfish in Hawaii can churn out 840 pounds of eroded coral—i.e. white sand—per year. A single giant humphead parrotfish can produce 11,000 pounds of sand per year.
hope this helps!
