the theory of sea floor spreading or continental drift
plate tectonics
Trenches and undersea mountains :)
at an oceanic to continental convergent boundary trenches and volcanic mountains can form. at an oceanic to oceanic convergent boundary trenches and volcanic islands can form. at a continental to continental convergent boundary fold mountains can form
when two plates collide they form trenches.
1. Oceanic trenches. 2. Volcanic islands. 3. Volcanic mountains. and 4. Volcanic arcs.
It can cause earthquakes, volcanoes, oceanic trenches, mountains, tsunamis, and subduction.
plate tectonics
Deep-oceanic trenches are most abundant around the rim of the Pacific. Deep ocean trenches are surficial evidence for sinking of oceanic lithosphere into the mantle at a subduction zone.
an volcano is formed
Trenches and mountain ranges are both formed by tectonic plate movements. Trenches are formed where one tectonic plate is subducted under another, creating deep oceanic trenches. Mountain ranges are formed when tectonic plates collide, pushing up the Earth's crust to form high elevations.
Offshore trenches, also known as oceanic trenches, are depressions in the sea floor. They are the deepest parts of the ocean floor.
Subduction.
