As the plates move apart (very slowly), magma close magma Molten rock that is found within the Earth. rises from the mantle to fill the gap. This is also accompanied by earthquakes.

Divergent boundaries occur along spreading centers where plates are movingapart and new crust is created by magma pushing up from the mantle. Picturetwo giant conveyor belts, facing each other but slowly moving in oppositedirections as they transport newly formed oceanic crust away from the ridgecrest. Perhaps the best known of the divergent bounda...
The size of the Earth has not changed significantly during the past 600million years, and very likely not since shortly after its formation 4.6billion years ago. The Earth's unchanging size implies that the crust mustbe destroyed at about the same rate as it is being created, as Harry Hesssurmised. Such destruction (recycling) of crust takes place ...
The zone between two plates sliding horizontally past one another is calleda transform-fault boundary, or simply a transform boundary. Theconcept of transform faults originated with Canadian geophysicist J. TuzoWilson, who proposed that these large faults or fracture zonesconnecttwo spreading centers (divergent plate boundaries) or, less commonly, ...
Not all plate boundaries are as simple as the main types discussed above.In some regions, the boundaries are not well defined because the plate-movementdeformation occurring there extends over a broad belt (called a plate-boundaryzone). One of these zones marks the Mediterranean-Alpine region betweenthe Eurasian and African Plates, within which sev...
We can measure how fast tectonic plates are moving today, but how do scientistsknow what the rates of plate movement have been over geologic time? Theoceans hold one of the key pieces to the puzzle. Because the ocean-floormagnetic striping records the flip-flops in the Earth's magnetic field,scientists, knowing the approximate duration of the rever...
A. destructive plate margin. usually involves an oceanic plate and a continental plate. The plates move towards one another and this movement can cause earthquakes. As the plates...
Apr 24, 2024 · At an ocean-continent convergent boundary, the oceanic plate is pushed under the continental plate in the same manner as at an ocean-ocean boundary. Sediment that has accumulated on the continental slope is thrust up into an accretionary wedge, and compression leads to thrusting within the continental plate (Figure \(\PageIndex{7}\)). The mafic ...
Apr 26, 2024 · Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet. Each type of plate boundary generates distinct geologic processes and landforms. At divergent boundaries, plates separate, forming a narrow rift valley .
Plates move apart at mid-ocean ridges where new seafloor forms. Between the two plates is a rift valley. Lava flows at the surface cool rapidly to become basalt, but deeper in the crust, magma cools more slowly to form gabbro.
How do plates move? The mechanism by which tectonic plates move is still a subject of much debate among Earth scientists. The Earth is dynamic thanks to its internal heat, which comes from deep within the mantle from the breakdown of radioactive isotopes.
