Convection currents occur in the semi-molten mantle. They are created by heat within the earth. As the mantle heats, the rock rises. When it cools, it sinks back down. This movement causes changes in the surface of the Earth.
They change the Earth's surface by shifting the plates causing them to fault. Faulting can create earthquakes ridges and mountains witch of coarse change the surface greatly.
Convection currents are formed in the Earth's mantle
Mantle convection is the slow motion of the Earth's silicate mantle, caused by convection currents that carry heat from the interior to the surface of the Earth. Mantle convection causes the tectonic plates to move around the Earth's surface, causing earthquakes, tsunamis, and volcanic activity.
Most convection currents exist in the mantle, the layer below the Earth's crust. As the semi-molten rock heats up, it rises closer to the surface as magma and hence cools on the earth surface to form rocks.
Surface currents are caused by wind, and affected by the rotation of the Earth and the gravity of the moon (tides). When the oceans are deep, convection within the layers can also affect the flow of currents. * While wind currents are greatly affected by uneven heating of the Earth's surface, there is no corresponding heating of the ocean bottom by the Sun. So currents do not form spontaneously at depth.

Convection currents rotate in the Lithosphere, which causes the surface of the Earth to move.

No. Convection currents are the circular motion of earth's wind. If the earth did not rotate, convection currents would not be. Does that make sense?
Via convection currents and hot spots in the mantle.
Earth's Plates
convection currents are when hot rock from deep inside the the earth rises but cooler rock near the surface sinks
Convection Currents affect earth by slowly moving the tectonic plates
