what is the difference between plate kinematics and plate dynamics
Answers
Answer:
Plate Kinematics: actualism is the idea that features in the rock record are to be explained by looking at the present-day world. It's common in sedimentary courses to use the 'present as the key to the past'.
In courses on structural and metamorphic processes, it has historically been difficult to apply an actuality approach, because at present the processes are occurring deep beneath the surface. This has changed in recent years. GPS systems enable us to measure plate movement and the distortion of the lithosphere; geophysical investigations allow us to infer the physical state of deep crustal and mantle rocks.
This course takes an actuality approach to deformation. We look first at plate kinematics to determine the rates and types of deformation that might be occurring at the present day. We will use this as a framework for interpreting the past.
Plate Dynamics: The idea that the surface of the Earth is broken into movable plates is an appealing one. It's not a particularly difficult concept, and it simplifies our understanding of Earth processes and features, and besides that, it unifies the Science of Geology.
