Differences in temperature on earth
Unequal heating of earth’s surface
Convection currents in the asthenosphere helps form subduction zones at convergent boundaries and ridges at divergent boundaries. This slow and continuous convection causes the plates on earth's crust to move.
In what two places do convection currents form when the Sun heats Earth
This happens when the are different .
Convection currents in the earth's mantle cause the plates to move. When this happens, mountains can form.

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 inside the Earth happens. The part where the convection currents go up, it brings up materials from the mantle like rocks. This forms new crust. When the convection currents go down, it brings down some older, colder oceanic crust to the mantle, destroying it. In conclusion, the crust is formed and destroyed when convection currents inside the Earth happen.
