Question

What is the speed of a tectonic plate?

Answer 1

The speed of tectonic plates varies depending on the specific plate and its location. Generally, tectonic plates move at rates ranging from about 1 centimeter (0.4 inches) to 10 centimeters (4 inches) per year. For example, the Pacific Plate moves at about 7 to 11 centimeters per year, while the North American Plate typically moves around 2.5 centimeters per year. This movement is driven by processes such as mantle convection, slab pull, and ridge push. Despite their slow motion, the cumulative effect of this movement can lead to significant geological events such as earthquakes, volcanic eruptions, and the formation of mountain ranges over geological timescales.
