Very slowly on the order of tens of millimetres per year.
For example the Mid Atlantic Ridge is spreading at around 25 mm/yr where as spreading centres in the Pacific tend to be faster with rates up to around 100 mm/yr.

Here is a link to my page there I have made some illustrations where I have animated the drift the way I believe they have drifted: http:/www.aspevik.net/animation.htm
But I have a picture here over the plates how they drifting today.

What are the 3 forces that scientists hypothesize move lithospheric plates?
scientist thought someone moved it
Do convergent plates move away from each other?
they move against one another
What explains the movement of the earth's crust?
The earth's crust moves because the earth has tectonic plates that move because the magma under the earth's surface is constantly boiling. Since the water moves, it causes the earth's crust to move.
Why do tectionic plates move?
Shifting Tectonic PlatesThey move because the hot air compressed underneath them builds up and it must be let out somewhere. This then moves tectonic plates forcing them to rub up against each other creating pressure. Eventually these plates will either crack or brake resulting in an earthquake. Like a jiggsaw puzzel, the Earth's crust is broken up into tectonic plates that move. When they colide they create what we call an EARTHQUAKE .
At what type of boundary do plates move together?
This is a convergent plate boundary, the plates move towards each other. The amount of crust on the surface of the earth remains relatively constant. Therefore, when plates diverge (separate) and form new crust in one area, the plates must converge (come together) in another area and be destroyed. An example of this is the Nazca plate being subducted under the South American plate to form the Andes Mountain Chain. got this from:http://www.moorlandschool.co.uk/earth/tectonic.htm
What is the surface on which the lithospheric plates move around earths surface?
Lower mantle is the surface on which the lithospheric plates move around earths surface.
What the large thin plates that move relative to one another on the outer surface of the earth?
They are called tectonic or lithospheric plates.
What does the lithospheric plates move on?
Aesthenosphere
How often do lithospheric plates move?
They constantly move. EDIT: Lithospheric plates move only about a few centimeters a year. Hope this helps! ~SLL
Do lithospheric plates move often?
They constantly move. EDIT: Lithospheric plates move only about a few centimeters a year. Hope this helps! ~SLL
Do plates move because of gravity?
No, plates do not move because of gravity. They move because of the convection currents in the Earth's interior. The heat rises up from the core and moves the lithospheric plates across Earth's surface. The main source is heat left over from the formation of our planet.
Do lithospheric plates constantly move?
Yes.
What is it called when two lithospheric plates move apart?
Continental Plates
Do lithospheric plates move quickly or slowly?
The plates move slowly. Three centimeters a year.
Why do lithospheric plates move constantly?
Its denity Differences
What happens to lithospheric plates when an earthquake occurs?
Lithospheric plates, which also are called tectonic plates, move towards or away from each other when an earthquake occurs.
How do the lithospheric plates move each year?
5 centimeters.
