Most of the trenches are located along the margin of the pacific ocean. Ex. the west coast of South America
The east coast of North America, west coast of africa
The eastern coast of South America is a passive margin, rather than a plate boundary.

The widest continental shelf in Florida is the Gulf continental shelf. It is along the central-west coast of the state.

Passive continental margin.
The U.S. east coast is not considered an active continental margin because there are no plate boundaries near it. Off the coast there is merely a slope with a transition from continental to oceanic crust.
It is a passive continental margin. There is no subduction or convergence.
The east coast of North America, west coast of africa
The eastern coast of South America is a passive margin, rather than a plate boundary.
Passive continental margins are not areas of convergence. There is little volcanic and earthquake activity on passive margins. Active margins are areas of convergence where one plate is descending beneath another. They are associated with volcanic and earthquake activity.

The Continental Divide in South America runs along the west coast, spanning from the southern tip of the continent in Chile and continuing north through countries like Peru and Ecuador. This natural geological feature separates the flow of water between the Pacific Ocean and the Atlantic Ocean.
These arc systems form at collision plate margins where an oceanic plate is being subducted under a continental plate. As the oceanic plate melts, the magma rises and finds cracks in the continental plate above and creates volcanoes. These volcanoes occur all the way along this plate margin. For example the cascade volcanic arc on the north west coast of USA.

No, Lewis and Clark only explored from the east coast of the continental United States to the west coast of the continental United States.
