warmer material will move upward were it cools then fall back to the bottom so it can start the cycle (convection current) once again
A convection current, however, this can also occur with gases.

A convection current in air will have warmer air near to the heat source and this will rise. Then it gradually loses heat to the surroundings and sinks again, so there is warmer air in parts of the current and cooler air in other parts.
This circular flow is called a convection current. It occurs when warmer fluid rises and displaces colder fluid, creating a continuous circulation pattern. Convection currents play a key role in various natural phenomena, such as ocean currents and atmospheric circulation.
In a convection current, air molecules near a heat source become energized and rise due to lower density. As these molecules cool, they become denser and sink back down, creating a circular motion of air flow known as a convection current.
Yes. Convection is a type of energy and a convection current is, well, the phrase for its currents. So yeah, convection and convection current are the same.
convection - as the water near the heat source gets warmer, it becomes less dense and rises, creating a current that circulates the water in the pan.
An example of conduction is when a metal spoon in a hot drink gets hot at the handle end. An example of convection is when warmer air rises, causing cooler air to move in and take its place, creating a convection current.
The type of current that creates warmer climates along a coastal area is a warm ocean current. Warm ocean currents bring warm water from the tropics to higher latitudes, resulting in milder temperatures along the coast.
im pretty sure it means what happens when molten material rises and then what happens when it sinks
the form of energy would be heat. convection currents are caused by uneven heating of air or fluid. The warmer fluid is more boyant than the cooler fluid, so it floats to the top, and creates a "convection current"
A convection current flows in a circular pattern, with warmer material rising and cooler material sinking (due to density differences). It should not be used with conveNtional current in electricty.
