The process by which molten material adds new oceanic crust to the ocean floor.
mid-ocean ridge
ocean trench
sea-floor spreading
subduction
An undersea valley that represents one of the deepest parts of the ocean.
mid-ocean ridge
ocean trench
sea-floor spreading
subduction
The boundary where two plates move against each other and ultimately one is pushed under another. This is where volcanoes and mountains form and earthquakes can be felt.
Convergent
Divergent
Transform
The boundary where two plates move away from each other.
Divergent
Convergent
Transform
