GEOLOGY

Detailed explanation-1: -Convection currents drive the movement of Earth’s rigid tectonic plates in the planet’s fluid molten mantle. In places where convection currents rise up towards the crust’s surface, tectonic plates move away from each other in a process known as seafloor spreading (Fig.

Detailed explanation-2: -These 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 back towards the core. As the magma sinks, it drags the plates across the surface of the Earth.

Detailed explanation-3: -The rising heat of convection currents moves the almost-liquid rocks. The pressure of convection bends rocks until they break completely. The pressure of convection bends rocks until they break completely. They always include oxygen and silicon.

Detailed explanation-4: -convection currents are a process in which the materials inside the mantle heat up and rise to the surface whilst the cooler liquid sinks; as it sinks it then heats up and rises again. This continuous cycle is established: hot liquid rising, cold liquid descending. These currents cause the tectonic plates to move.

Detailed explanation-5: -The heat from radioactive processes within the planet’s interior causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift.
