About 350 million years ago, the Antler orogeny
(see link below) began to deform the Paleozoic rocks of Nevada's Great Basin and western Utah to lay down the basis of what would become The Rockies. For 270 million years, the Antler volcanic island arc terrane collided with the western coastal area of the North American plate, near what is today's border area of Nevada and Utah.
The current Rockies came up between 80 and 55 million years ago during what is called the Laramide orogeny
(see other link below), with the growth of the southern part of the Rockies believed to have been caused by the subduction of the Farallon plate taking a shallowly-angled dive beneath the North American plate.

What kind of plate boundary is the klyuchevskaya sopka's on?
convergent plate boundary
What plate boundaries move away from each other?
The kind of plate boundary that moves apart is a Divergent Plate Boundary
What kind of plate boundary does a plateau form on?
Trenches are formed at convergent plate boundaries involving at least one oceanic plate, where the more dense plate subducts under the less dense plate.
What kind of plate boundary commonly forms a chain of volcanoes?

What kind of plate boundary forms a deep sea trench?
Convergent
When one tectonic plate pushes underneath another what kind of boundary forms?
subduction zone or continental plate
What kind of plate boundary forms sea trenches?
Ocean trenches are associated with subduction zones, which are convergent plate boundaries.
How are mountains chains formed?
When two edges of tectonic plates collide (convergent boundary) they can cause a crumpling effect and an upthrust to form mountains. The Himalayas, for instance, were formed when the Indian Plate crashed into the Asian Plate. Convergent boundary also applies to the situation where one plate moves under the other (subduction) this kind of plate boundary can also form mountain chains. An example of this is the Andes mountains.
