An "orogeny" is a mountain building event that happens when two tectonic plates collide. which of following is true about the laramide orogeny? select one or more: 0 a. it elevated the colorado plateau o b. it greatly jumbled all of the layers of the grand canyon o c. it happened in the precambrian o d. it caused the great unconformity

It elevated the Colorado Plateau.

It happened in the Precambrian.

It caused the Great Unconformity.

Explanation:

Laramide Orogeny was a phase in the mountain building in North America starting in late Cretaceous, period 70-80 million years ago. And ended about 55 million years ago. Due to the oceanic crust was undergoing slab subduction i.e magnetism occurred at a shallow margin, underlying oceanic lithosphere that caused a drag in the roots of the continental lithosphere. Occurring around the volcanic arc of the Andes. The tectonic settings produced a type of deformation in continental plates upliftment and basins.
