A. Convergence of Plates
As continental plate converges with an oceanic plate, the (1)
dives under the (2)
(continental, oceanic) plate
called (3)
(continental, oceanic) plate. The process of diving down towards the mantle is
(subduction, floatation). When the leading edge of the subducting plate reaches the
mantle, it melts turning into (4)
(magma, crust) which builds up a pressure making it push the
ground above it forming at the surface a (5)
(volcano, mountain). At the oceanic plate, a
depression called (6)
(trench, fault) is formed along the boundary. Parallel to it, a series of volcanoes
called (7)
(volcanic island, volcanic island arc) may be formed. Simultaneous with the
convergence, the ground may shake and so, we experience an earthquake. This shaking may disturb the
water surface and may make the water flip upwards to a certain height. This event is called
(8)
(tsunami, wave).
When two oceanic plates converge, the denser plate subducts. Once its leading edge reaches the
mantle, it melts into a magma, builds up a pressure that makes it push the ground above it, forming a
(91
(volcanic island, mountain). At the collision zone, a crack called (10)
(trench,
fault) is formed. This depression could be the cause of the shaking of the ground which is felt as an
(earthquake, storm). At the water surface, the overriding plate may push a big amount of
water causing it to flip upwards forming a (12)
(tsunami, wave).
The convergence between two continental plates results to a landform called
(13)
(volcanic arc, mountain ranges). Since both plates have the same densities, no plate
subducts under the other. There is (14)_
(no volcanic, volcanic) formation. However, since
(earthquake, storm) may be felt in nearby
the ground moves, a phenomenon called (15)
places.
