The answer is D! Hope that helped
Everybody is wrong :/
The true answer is A) principle of superposition
The deformation of sedimentary strata in the American West during the Jurassic Period was caused by the Farallon plate subducting beneath the North American plate.
<h3>What purpose served the Farallon plate?</h3>
About 100 million years ago, the Farallon oceanic plate was placed between the diverging Pacific & North American plates, which later united to form the San Andreas fault. The Farallon was subducted beneath North America and then plunged deep into the mantle when those plates clashed, causing a significant component of the structure to disappear.
<h3>When did the Farallon plate go under the ocean?</h3>
50 million years ago, at the start of the series, the Farallon plate started to press against the North American continent, sinking beneath it and forming mountain ranges like the Rocky Mountains. The Farallon plate was subducting as a single unit along the entire length of North America, from Alaska down past Mexico.
