What is the average movement of lithospheric plates?

Movement of lithospheric plates:

The movement of lithospheric plates takes place due to the convection current arising in the inner mantle caused by hot rising molten rocks and cool sinking magma thereof. The tectonic or the lithospheric plates start drifting along with the convection currents from the underlying mantle.

Answer and Explanation:

The movement of the lithospheric plates takes place along three types of boundaries:

- the convergent boundaries, where the plates move into one another causing folding of the boundaries to form mountains,

-or along the divergent boundaries where they move away from each other.

-and transform boundaries where they slip past each other.

The average detectable drift of the plates is three to five centimeters in a year. This is the rate of movement of the lithospheric plates.
