Upwelling currents in the molten material beneath the crust.
The rocks that make up the crust are light, compared with the metal-rich material beneath. The crust floats on top like an iceberg. Slow-moving currents underneath propel the continents around the surface
The movement of magma underneath earth's crust.
The Earth's crust moves primarily due to tectonic plates that are driven by convection currents in the mantle. These movements occur at different types of plate boundaries, including divergent, convergent, and transform boundaries, leading to geological activities. Factors such as seafloor spreading and subduction zones also play a crucial role in the movement of the crust.
