Continental lithosphere averages 120 miles, while oceanic lithosphere averages 60 miles. The temperature and pressure of the lithosphere increases with depth. High temperatures drive the movement of tectonic plates, whilst pressure builds up at tectonic plate boundaries, resulting in earthquakes and ... crypto testimonials
