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.

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.

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.

separation of powers, therefore, refers to the division of government responsibilities into distinct branches to limit any one branch from exercising the core functions of another.   the intent is to prevent the concentration of power and provide for checks and balances.  

the traditional characterizations of the powers of the branches of american government are:

* the legislative branch is responsible for enacting the laws of the state and appropriating the money necessary to operate the government.

* the executive branch is responsible for implementing and administering the public policy enacted and funded by the legislative branch.

* the judicial branch is responsible for interpreting the constitution and laws and applying their interpretations to controversies brought before it.

forty state constitutions specify that government be divided into three branches:   legislative, executive and judicial.   california illustrates this approach; "the powers of state government are legislative, executive, and judicial.   persons charged with the exercise of one power may not exercise either of the others except as permitted by this constitution."

while separation of powers is key to the workings of american government, no democratic system exists with an absolute separation of powers or an absolute lack of separation of powers. governmental powers and responsibilities intentionally overlap; they are too complex and interrelated to be neatly compartmentalized. as a result, there is an inherent measure of competition and conflict
