Yes, convection in the mantle does often occur in tabular sheets when warm rock rises. This process is known as sheet-like flow, where warm material rises in broad, sheet-like structures, carrying heat upwards in the mantle. These tabular sheets play a key role in driving the movement of tectonic plates and shaping the Earth's surface.
When a warm fluid rises and a cool fluid sinks.
I believe that is convection.
The flow of mantle effects convection currents in the mantle. This process happens as hot material within the mantle begins to rise. As it rises, it begins to cool and then sinks. This process repeats as a cycle of convection currents.
When it is heated it becomes less dense (i.e. lighter). The more dense (i.e. heavier) magma sinks while the less dense magma rises to the top. It will eventually cool again causing a convection current within the mantle.
Convection in the mantle drives the movement of tectonic plates. As hot material rises and cooler material sinks in the mantle, it creates circulation patterns that push and pull the overlying tectonic plates. This convection process is a key driving force behind plate tectonics and the movement of Earth's lithosphere.

A rising convection current.
the convection currents will be set in motion because the heat from the mantle rises and causing it to change Earth's density & force of gravity

The intense heat in the Earth's core causes molten rock in Earth's mantle to shift. That causes a pattern called a convection cell which forms when material rises, cools, and sinks. When the material sinks, it is warmed and rises again.
