Continental plate drift
Continental plate drift is the slow movement of Earth's tectonic plates driven by forces within the planet's mantle.
Also known as: tectonic plate drift speed
How big is it?
8 × 10⁻¹⁰ m/s
Representative plate speed · representative
Typical recorded range: 3 × 10⁻¹⁰ m/s to 3 × 10⁻⁹ m/s.
A little perspective
Fingernail growth is about 1.25 times larger on this measurement.
Fingernail growth: Fingernail growth is the process by which human fingernails gradually extend from the base of the nail bed over time.
Measurements, assumptions & sources +
Continental plate drift
A representative tectonic-plate speed of 8 × 10⁻¹⁰ m/s, about 2.5 cm per year. Plates move at different rates and directions.
The marked representative plate speed is calibrated. Unmeasured illustration details are representative.
Fingernail growth
A curated fingernail growth comparison anchor. The representative value and any stated range preserve the backlog measurement convention; operating or experimental conditions can change real observations.
Defined examples — our methodology
The marked speed is calibrated. Unmeasured illustration details are representative.

Why this measurement?
Why we use 8 × 10⁻¹⁰ m/s
For comparison, this page uses representative plate speed. This is labelled representative; the central value is useful for comparison, while real values or measurement solutions can vary. The recorded range is 3 × 10⁻¹⁰ m/s to 3 × 10⁻⁹ m/s.
A representative tectonic-plate speed of 8 × 10⁻¹⁰ m/s, about 2.5 cm per year. Plates move at different rates and directions.
