Jupiter's moons - Europa and Ganymede possibly have oceans of liquid water under their crust. Saturn's moon - Enceladus also has a possible ocean of water under it's crust.
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.
When plates are actually coming towards each other, there can be two different boundaries: collision and destructive boundaries. In a collision boundary, there are earthquakes, and fold mountains are created from the plates pushing up against each other, like the Himalayas. When there is a destructive boundary, like the Eurasian and Pacific plates, the oceanic plate slides underneath the continental plate, being destroyed and causing earthquakes and volcanic eruptions. There are two other types of boundaries: conservative, where plates slide past each other, and constructive, where plates move away from each other.
There are no active volcanoes in Montana. You have to go further west to the Cascade Range to find volcanoes. The volcanoes in the Cascades are caused by the subduction of the oceanic crust under the continental crust.

Well, there is no "The" underwater warfare, but there is underwater warfare. Underwater warfare is battle or warfare that takes place under the ocean, like in a submarine.
Crust under the oceans is called oceanic crust.
oceanic crust
The crust under the ocean is typically about 3 to 5 miles (5 to 8 kilometers) deep.
The crust not under the ocean is called continental crust. It is thicker and less dense compared to oceanic crust and forms the landmasses on Earth's surface.
Earth's crust is far thicker under the continents.
You would be under the Earth's crust, which is the outermost layer of the Earth. The crust is typically between 5-70 km thick beneath the continents and around 5-10 km thick beneath the ocean basins.

Oceanic crust is thinner and denser than continental crust.
The thin crust of the planet floats on the molten core.
the continental crust is the plate crust formed under the continent (less density) as opposed to oceanic crustformed under the ocean(higher density)
the continental crust is the plate crust formed under the continent (less density) as opposed to oceanic crustformed under the ocean(higher density)
Because the oceanic crust is under water in the ocean and a continental crust is land such as the continents
