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. When two plates come together, it is known as a convergent boundary. When oceanic and continental crust collide at a subduction zone, one plate is forced under the other. ... At a divergent boundary, what is the relative motion of the ... Apr 25, 2017 · Divergent boundaries occur where plates are spreading apart. This spreading is caused by convective forces in the molten magma below them. As they slowly spread apart, this fluid basalt lava fills the gap and quickly solidifies, forming new oceanic crust.

The first sort of plate boundary is called a divergent boundary, or spreading center. At these boundaries, two plates move away from one another. As the two move apart, mid-ocean ridges are created as magma from the mantle upwells through a crack in the oceanic crust and cools. A. divergent B. oceanic C. convergent D. transform Weegy: Two tectonic plates move toward each other at divergent boundaries User: Fuels derived from living things are known as A. synthetic fuels. B. hybrid fuels. Divergent Plate Boundary - Oceanic: When a divergent boundary occurs beneath the ocean, the rising convection current below lifts the lithosphere producing a mid-ocean ridge. Extreme forces stretch the lithosphere and produce a deep fissure. When the fissure opens, pressure is reduced on the super-heated mantle material below. Divergent boundaries are constructive boundaries because new crust is generated by magma pushing up from the mantle as the plates pull away from each other. Seafloor Spreading. Divergent boundaries in the middle of the oceans cause seafloor spreading. As the oceanic plates move apart they produce cracks in the ocean floor.

In plate tectonics, a divergent boundary or divergent plate 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. Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges. Divergent boundaries also form volcanic islands, which occur when the plates move apart to produce gaps that molten lava rises to They’re both convergent zones, but when an oceanic plate converges with a continental plate, the oceanic plate is forced underneath the continental plate because oceanic crust is thinner and denser than continental crust. Heat generated in Earth's core creates convection currents in Earth's Mantle causing lithospheric plates on Earth's surface to move | Tension Pull <-- -->

Plate Tectonics Learning Objectives: - Describe the differences between oceanic and continental crust, including their respective properties of density, composition, temperature and thickness. - Predict how changes in composition and temperature change crust density and buoyancy.

A divergent boundary forms where two plates separate. When the seafloor spread at a mid-ocean ridge, lava erupts, cools, and forms new oceanic crust. divergent plate boundaries can also exist in the middle of a continent. They pull continents apart and form rift valleys. The east african Rift is an example of a continental rift. Plate boundary zones -- broad belts in which boundaries are not well defined and the effects of plate interaction are unclear. Illustration of the Main Types of Plate Boundaries [55 k] Divergent boundaries. Divergent boundaries occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle. At divergent plate boundaries, rift valleys and spreading ridges form as plates pull away from each other. At convergent plate boundaries, where plates are coming together, subduction zones form when an oceanic plate and a continental plate collide and mountains build when two continental plates collide. A divergent plate boundary is forming a narrow linear sea (basaltic oceanic crust) separating two slabs of continental crust, northwest Africa and the Arabian Peninsula. The Black Sea is forming in the forearc region of the convergent plate boundary between the African Plate and the Eurasian Plate. At convergent plate boundaries where oceanic and continental crust meet _____ . no associated volcanism occurs oceanic crust is subducted continental crust is subducted oceanic crust is created. One remarkable realization associated with the discovery of seafloor spreading was that _____ .

May 08, 2012 · New oceanic lithosphere is created when basalt magma from the mantle is forced up into fractures in the crust. The submarine mid-ocean ridges form the longest mountain ranges in the world. The most famous oceanic divergent boundary is the mid Atlantic ridge, the 10,000 mile unseen mountain range that dominates as the longest of them all, making the Atlantic Ocean continually bigger, since the Triassic period. Divergent Plate Boundaries. The mid-ocean ridges are one of the three basic types of plate boundaries. We call them divergent plate boundaries because the plate material on either side of the margin is spreading apart. The spreading is a result of forces pulling the oceanic lithosphere on either side of the ridge in opposite directions. Plate Tectonics Learning Objectives: - Describe the differences between oceanic and continental crust, including their respective properties of density, composition, temperature and thickness. - Predict how changes in composition and temperature change crust density and buoyancy. The ultimate divergent boundary is the mid-Atlantic Ridge in the middle of the Atlantic Ocean. Convergent Plate Boundaries When two plates converge, the result depends on the type of lithosphere the plates are made of.

Most seismic activity occurs at three types of plate boundaries—divergent, convergent, and transform. As the plates move past each other, they sometimes get caught and pressure builds up. When the plates finally give and slip due to the increased pressure, energy is released as seismic waves, causing the ground to shake. Plates are made up of two types of crust – oceanic and continental; oceanic crust is thinner and denser than continental crust. A single plate can have both continental and oceanic crust. Gravity and mantle convection are two driving forces for the movement of plates.

  • The oceanic plates are themselves formed from the divergent boundary, so probably not. Even if a new rifting occurred exactly at the boundary, the result would eventually be that the ocean floor surrounds the divergent boundary. A very simplified model of an ocean would have a divergent boundary in the middle. This oceanic spreading center might have basaltic volcanic islands along it, and two mirrored plates on each sides, pushing towards neighboring continental or oceanic plates. The Cascades are a chain of volcanoes at a convergent boundary where an oceanic plate is subducting beneath a continental plate. Specifically the volcanoes are the result of subduction of the Juan de Fuca, Gorda, and Explorer Plates beneath North America. Discussed this under Divergent Plate Boundaries. Granite is intrusive: forms deep within the crust. Associated with Convergent boundaries. Heavier oceanic basalt is subducted beneath the lighter continental materials.
