Convergent plate boundary is the area in earth where the collision of lithosphere plates occur and the lighter plates stay on top of the denser plates after collision leaving the denser to slide down into the earth core. and the effect of this is ...
What features form at plate tectonic boundaries?
WebA fault is formed in the Earth's crust as a brittle response to stress. Generally, the movement of the tectonic plates provides the stress, and rocks at the surface break in response to this. Faults have no particular length scale. If you whack a hand-sample-sized piece of rock with a hammer, the cracks and breakages you make are faults. When a divergent boundary occurs beneath oceanic lithosphere, the rising convection current below lifts the lithosphere, producing a mid-ocean ridge. Extensional forces stretch the lithosphere and produce a deep fissure. When the fissure opens, pressure is reduced on the super-heated mantle … See more The Mid-Atlantic Ridge is a classic example of this type of plate boundary. The Ridge is a high area compared to the surrounding seafloor because of the lift from … See more Visit the Interactive Plate Boundary Map to explore satellite images of divergent boundaries between oceanic plates.
