Convection
This movement is an example of convection. As the mantle is heated from below, warmer, less dense material rises toward the crust, while cooler, denser material sinks back down. This convection process drives plate tectonics and influences the movement of Earth's lithosphere.
When the heated part of the mantle rises through the Earth's crust, it can create volcanic activity as magma reaches the surface. This process is known as mantle convection and is responsible for the movement of tectonic plates and the formation of volcanic hotspots.
The heating of Earth through convection occurs in the mantle, where the heat from the core causes the molten rock to circulate in convection currents. As the hot material rises and the cooler material sinks, it creates a continuous cycle of heat transfer, which ultimately warms the Earth's surface through the process of convection.
Convection is the transfer of heat through the movement of fluids such as air or water. It occurs in Earth's layers, specifically in the mantle, through the process of mantle convection. This movement of hot, less dense material and cooler, denser material in the mantle drives the motion of tectonic plates on the Earth's surface.
The boundary that separates the Earth's crust and the cooler part of the mantle is called the Mohorovičić discontinuity or Moho. It marks the transition between the Earth's crust and the uppermost part of the mantle.

I believe that is convection.

The mantle is hotter than the crust.
Actually, heated materials are less dense. When heat is applied to a substance such as liquid, it becomes less dense. It is this less dense and heated material that rises because it weighs less. The part of the mantle that is more dense would be any substance that is cooling and is sinking down.
Earth's mantle is mainly heated by the decay of radioactive isotopes and residual heat from the formation of the planet. This heat causes convection currents in the mantle which drive plate tectonics and other geological processes.
