Question

Geologists Xavier Le Pichon, Dan McKenzie, and W. Jason Morgan brought together

these ideas into one formal theory called plate tectonics. Which ideas make up the

theory of plate tectonics? Mark all that apply.

Answer 1

Answer: The answer is:

Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core.

Step-by-step explanation:

Jason Morgan, Dan McKenzie and Xavier Le Pichon. These authors are considered the “founding fathers” of plate tectonics. These authors founded geotectonics (and almost all geology) on Euler’s theorem, imposing Eulerian motion on all lithospheric plates.

In Late 1967 to mid-1968, Dan McKenzie and Robert L. Parker, Jason Morgan and Xavier Le Pichon, amongst others, showed that crustal motions on Earth approximate rigid body rotations on a sphere and that plates conforming the Earth’s upper layer have rates of motion that can be calculated thanks to paleomagnetic data.
