Tectonic plates are moving due to the convection of heat at asthanosphere. The moving rate is about 50 to 100 mm per year. You can compare the speed of moment to the growth of your nail. This causes accumulation of stress at its boundary. When the stress exceeds its bearable limit causes earthquake. Small earthquakes are welcome measures for release of energy then and there. If the accumulated energies are more it may cause heavy damage during its release through earthquakes.Visit my slides.

It does not have any objective in the sense of tectonic forces trying to "do" one thing or another. Plates move around due to currents in the mantle, and where the mantle breaks through and causes spreading..

I cannot argue FOR and AGAINST at the same time. I am FOR. Your question will arouse controversy among our friends here and that's understandable. Let me put it this way. Questions: Did we and the universe just sprout out of nowhere like mushrooms? Does one, without mental dishonesty, think we all appeared out of thin air, from invisibility to visibility, from nothingness to existence? There must be a First Cause, or God. It is difficult to think without contradiction that there is not. If it is otherwise than I believe there is, then where did we all come from, and how else did we come into existence? Of course, science has observed life forms will introduce themselves under certain conditions but conditions are existence themselves. So how do you explain existence within existence without the First Cause? Just an argument OK. Nothing personal. I will respect yours as well. Thanks. Cheers!

Natural forces don't have desires, plans, or goals as far as we know. Maybe if you phrase your question in a less anthropomorphic manner an answer can be given.
