The Earth’s whole lithosphere is broken into several rigid sections called plates that move constantly. Do lithospheric plates move quickly or slowly? What must be the reason behind the motion of the massive lithospheric plates?
This module contains different activities that will help you understand the driving force behind plate tectonics.
After going through this module, you should be able to:
1. describe the possible causes of plate movement (S10ES-Ia-j-36.5); and
2. recognize the process of convection current in the mantle.Science10_q1_mod4_earths-mechanism_ver2
