WebA new crust is formed when the tectonic plates move in different directions, some cracks occur in the middle part and lava comes out and a new crust is formed. ... How does tectonic plate deformation occur? Precipitation currents are formed in the mantle, and the reason for the formation of the mantle is that there is a semi-liquid fluid ... WebThese plates move due to convection currents in the mantle. Heat from the core makes magma in the mantle rise towards the crust. As the hot current nears the crust, it begins to cool and sink...
