A material that has a larger density than the surrounding material has the natural tendency to sink.
Cool rock material sinks in the mantle during convention because it is more dense than the surrounding warmer rock. As the cooler rock sinks, it displaces the warmer rock, creating a cycle of sinking and rising that drives mantle convection. This process helps transfer heat in the Earth's interior and drives plate tectonics.
Erosion, transportation of the eroded material, deposition of this material then lithification.

Cool rock material sinks in the mantle because it is denser than the surrounding warmer rock. As the mantle heats up, the rock becomes less dense and rises due to convection currents. This process creates a cycle where cooler, denser material sinks while warmer, less dense material rises, facilitating the movement of tectonic plates and driving geological activity.
It takes place in Washington. (Not Washington D.C.) ;P
it undergoes transformation into another rock.

Yes there is
It is called the 'protolith' or 'parent rock'.
The term for the movement of rock material from one place to another is erosion. This can happen through processes like wind, water, ice, or gravity.
In the mantle, convection occurs due to differences in temperature and density. Cooler rock material, being denser, sinks towards the Earth's core, while warmer rock material, which is less dense, rises towards the surface. This movement creates a continuous cycle, where rising warm rock cools and sinks again, driving the convection process that influences plate tectonics and geological activity.
