Q. Which of the following plates has the slowest rate of movement at less than 2.5 cm/year ?
✅ Correct Answer: (A)
Arctic Ridge
Explanation: The movement of the crustal plates (due to convection currents in the mantle) causes the formation of various landforms and is the principal cause of all earth movements.The Arctic Ridge has the slowest rate (less than 2.5cm/year) and the East Pacific Rise in the South Pacific (about 3,400 km west of Chile), has the fastest rate (more than 15cm/year).
