Seafloors typically spread at an average rate of 2 to 5 centimeters per year at mid-ocean ridges. Over a hundred years, this translates to approximately 200 to 500 centimeters, or 2 to 5 meters. The exact rate can vary depending on the specific tectonic plate and geological conditions in that region.

If tectonic plates move at a rate of 2 cm per year, in 1000 years they would have moved a distance of 2000 cm, which is equivalent to 20 meters.
A continent typically moves about six centimeters each year. So in 100 years, a continent will have moved six meters.

Tectonic plates typically move away from each other at rates ranging from a few millimeters to several centimeters per year. On average, the movement at mid-ocean ridges, where plates diverge, is about 2 to 5 centimeters annually. However, this rate can vary depending on the specific location and geological conditions.
MOVE
As a result of the conservation of angular momentum, the slowing of Earth's rotation is accompanied by an increase of the mean Earth-Moon distance of about 3.8 m per century, or 3.8 cm per year.
The North American Plate and the Eurasian Plate move apart from each other at a rate of approximately 2.5 centimeters (about 1 inch) per year. This movement occurs along the Mid-Atlantic Ridge, where new oceanic crust is formed as magma rises to the surface. This tectonic activity contributes to the widening of the Atlantic Ocean over geological time.
