UPSC CAPF – 2021
– In the Earth’s interior, these currents occur in the mantle, which is primarily solid but behaves plastically over long geological timescales, particularly in the upper part called the asthenosphere.
– The convection in the mantle is the primary driving force behind the movement of the tectonic plates that make up the Earth’s crust.
– The outer core is liquid iron-nickel, but convection here is responsible for generating the Earth’s magnetic field, not directly driving plate tectonics.
– The inner core is solid and extremely hot, but its convection is not relevant to plate movement.
