Facts About the Divergent Plate Boundary Explained with a Diagram Divergent plate boundaries are those tectonic borders where tectonic plates pull away from each other and form a new crust. ScienceStruck takes you through some interesting facts about these divergent boundary zones on this Earth.

A convergent plate boundary also known as a destructive plate boundary , usually involves an oceanic plate and a continental plate. The plates move towards one another and this movement.

Divergent Boundary Definition & Examples Video & Lesson Transcript
Divergent plate boundaries are locations where plates are moving away from one another. This occurs above rising convection currents. The rising current pushes up on the bottom of the lithosphere, lifting it and flowing laterally beneath it. This lateral flow causes the plate material above to be dragged along in the direction of flow.
Tectonic Plate Margins HubPages
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth's mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate boundaries.

Rates of motions of the major plates range from less than 1 cm/y to over 10 cm/y. The Pacific Plate is the fastest, followed by the Australian and.
Evolution of the Theory of Plate Tectonics Owlcation
Divergent Plate Boundaries At a divergent boundary, tectonic plates move apart from one another. They never really separate because magma continuously moves up from the mantle into this boundary, building new plate material on both sides of the plate boundary. The Atlantic Ocean is home to a divergent plate boundary, a place called the Mid.
Divergent boundary Wikipedia
Updated on January 17, 2020 Divergent boundaries exist where tectonic plates move apart from each other. Unlike convergent boundaries, divergence occurs between only oceanic or only continental plates, not one of each.

Divergent (Spreading) :This is where two plates move away from each other. Molten rock from the mantle erupts along the opening, forming new crust. The earthquakes that occur along these zones, called spreading centers, are relatively small.

In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts, which eventually become rift valleys.
Divergent Plate Boundaries Earth
Spreading Centers along Divergent Plate Boundaries. A spreading center is a linear area where new crust forms where two crustal plates are moving apart, such as along a mid-oceanic ridge. Spreading centers are typically seismically active regions in ocean basins and may be regions of active or frequent volcanism (Figure 4.7).

In the oceans, plates move apart at mid-ocean ridges. Lava rises upward, erupts, and cools. Later, more lava erupts and pushes the original seafloor outward. This is seafloor spreading. Seafloor spreading forms new oceanic crust. The rising magma causes the ridge to be buoyant. This is why there are mountain ranges running through the oceans.

Figure 2.4.1 2.4. 1: Faulting that occurs in divergent boundaries. In places where the continental plates are very thick, they reflect so much heat back into the mantle it develops strong convection currents that push super-heated mantle material up against the overlying plate, softening it.
Divergent Plate Boundaries Geology (U.S. National Park Service)
A divergent plate boundary often forms a mountain chain known as a ridge. This feature forms as magma escapes into the space between the spreading tectonic plates.
Labeled Divergent Plate Boundary Diagram
Most divergent boundaries are located along mid-ocean oceanic ridges (although some are on land). The mid-ocean ridge system is a giant undersea mountain range, and is the largest geological feature on Earth; at 65,000 km long and about 1000 km wide, it covers 23% of Earth's surface (Figure 4.5.1 4.5. 1 ). Because the new crust formed at the.
