The Solid Earth, Ch Plates, creep and convection: the mantle in motion
Problem
Two rigid plates, P and Q, rotate relative to one another about an Euler pole on the equator at 0.0∘N,10.0∘E, at a rate ω=0.55∘Myr−1. Find the speed of P relative to Q at a site on the boundary at 25.0∘N,100.0∘E. Take the Earth's radius as a=6371km.
