Earths forces of gravity
They move because of the heat from the outer core and the mantle.
core
Convection currents rese and sink through the mantle and the liquid outer core. In Earth's mantle, large amounts of heat are transferred by convection currents. Heat from the core and the mantle itself causes convection currents in the mantle.
The answer is that convection currents occur in both. Convection currents are just natures way of moving heat from one place (deep in the earth) to another place (closer to the surface) in the most efficient way possible.In the outer core, convection happens because the magma is liquid, so it flows easily. Also, since it contains moving charged particles, most scientists believe that the outer core generates the Earth's magnetic field.Convection curents also happen in the mantle, but they are slower because the mantle is mostly solid, so it flows very slowly. Convection currents in the mantle are believed to drag the tectonic plates with them, causing the continents to drift over long periods of time.Well the Earth's magnetic field is a result of the convective movement of the outer core.
The lithosphere is generally thought of as the crust and outer mantle of the earth. They're solid, and there are no convection currents in solids as we normally think of them. As we move inward toward the core of the earth, we begin to encounter molten rock (magma), and convection currents exist in this superheated fluid.
there are convection currents in the upper core.

core
It is mainly transferred by convection currents. If you have a science book, you could check there too. Just read carefully. :)
they both have convection currents
Convection currents in the mantle are streams of fluid produced by the process of heat transfer from one place to another. The earth gets very hot as you go nearer to the core. The mantle is thus heated up as it is right next to the core. As a result, convection currents are formed.*Core: It is a spherical zone that lies at the center of the earth.*Mantle: It is the layer surrounding the outer core of the earth.
The convection that causes Earth's magnetic field happens in Earth's molten outer core.

The inner core is solid, but the mantle is the only layer of Earth that flows in currents. These currents are caused by convection. If you don't know what convection is then you might as well look it up because I don't have a good definition.
