Question

Approximately how quickly do the Earth's crustal plates move? A. A few centimeters a year B. A few centimeters a month C. A few meters a year D. A few meters a month

Answer 1

The correct answer is - A. A few centimeters a year.

Earth's crustal plates move very slowly, between 2 cm and 5 cm (depending on the plate) annually. This is the reason why it takes millions of years for them to significantly change their position, and with it the appearance of our planet. These crustal plates are slowly moving around the planet because they are powered by flow in the interior mantle.
