Tectonic Plate Theory If oceanic and continental crust collides the denser one which is the oceanic crust will be subducted, go underneath, the continental crust. The high heat of the mantle causes the oceanic crust to melt into magma. If the crust gets cracked this allows magma to rise and come out of the crust as lava which will form Volcanoes. When two continental crusts collide, the crust is forced to go upwards which forms mountains.

- Best Answer: Magma is the molten material beneath Earth's crust. This material consists of rock, gases, and mineral crystals. The temperature of the magma can be as high as 5000 degrees Fahrenheit.The pressure is also very high since the magma supports the weight of Earth's crust.Lava is the molten rock that comes out of a volcano or from a fissure in Earth's surface.A fissure is a crack. The molten rock comes from the underground magma. Lava is thus magma that has broken through Earth's surface.est Answer: Magma is the molten material beneath Earth's crust. This material consists of rock, gases, and mineral crystals. The temperature of the magma can be as high as 5000 degrees Fahrenheit.

- Magma rises from the asthenosphere to the surface of the Earth.  After it reaches temperature upward to 1000 degrees Fahrenheit, the  magma starts to rise. Gases also aid in… pushing the magma toward  the surface, along with the tremendous pressure from the depth at  which it originates.

Magma tends to rise toward the earhs surface principally because? If the crust through which the magma passes is sufficiently shallow, warm, or fractured, and if the magma is sufficiently hot and fluid, the magma will erupt at the surface of the earth, possibly forming volcanoes.

- The solid crystals and gas bubbles provide resistance to deformation of the magma as a shear stress is applied. Therefore, a certain shear stress (the yield stress) must be applied to the magma before it will yield to deformation (begin to flow).

Geology Exam 1 Magma rises up through the area under the mid ocean ridge (going through the astheosphere, zone of partial melting and crystal mush, gab arrow and losing a little bit at each step) until finally some of the magma gets all the way to the surface and spills out of small submarine volcanoes, creating new ocean crust.

Under what conditions will cooling magma produce minerals with large crystals? When magma is deep in the crust it cools at a much slower rate, producing larger crystals than appose to rapid cooling lava which is above ground. (Source- 8th grade Science teacher) When magma is deep in the crust it cools at a much slower rate, producing larger crystals than appose to rapid cooling lava which is above ground.

Ocean basin The process by which new oceanic crust is formed by the upwelling of magma at mid-ocean ridges, resulting in the continuous lateral movement of existing oceanic crust. Seamount: An isolated volcanic mountain that often rises 3,280 feet (1,000 meters) or more above the surrounding ocean floor.

The Role of H 2 O in Subduction Zone Magmatism Annual Review of Earth and Planetary Sciences. Water is a key ingredient in the generation of magmas in subduction zones. This review focuses on the role of water in the generation of magmas in the mantle wedge, the factors that allow melting to occur, and the plate tectonic variables controlling the location of arc volcanoes worldwide.

Magma Magma often collects in magma chambers that may feed a volcano or solidify underground to form an intrusion. Magma is capable of intruding into adjacent rocks (forming igneous dikes and sills), extrusion onto the surface as lava, and explosive ejection as tephra to form pyroclastic rock.

New Ocean Crust May Form Slower Than Thought Scientists have thought that magmas that form new crust at fast-spreading ridges rise up from the depths, quickly crystallize, and then push away from the ridge to form new ocean floor.

- There are 2 important things to note: a) magma gets to the surface via a potentially complex network of fractures, caverns and pathways. (Each of these has a specific name which we will get to eventually) b) in the case of the divergent plate boundaries, the magma can move upward relatively quickly because it passes along planes of weakness.

Although submarine volcanoes may not produce the spectacular eruption events of some of their land counterparts, undersea volcanic activity is a constant process that shapes the features of the ocean. When magma reaches the level of the seafloor, it meets cold ocean water and quickly cools to form basaltic rock, often termed pillow lava due to its rounded shape. This pillow lava, along with slower-cooling magma beneath it, forms the vast majority of oceanic crust.olcanoes are common occurrences along the boundaries of Earth’s tectonic plates. These boundaries allow super-heated molten rock called magma, along with ash and gases, to rise through Earth’s crust and emerge on the surface, often dramatically.

How Volcanoes Work As the two plates separate, the mantle rock from the asthenosphere layer below flows up into the void between the plates. Because the pressure is not as great at this level, the mantle rock will melt, forming magma. As the magma flows out, it cools, hardening to form new crust.

- However, researchers say the current rise in magma is most likely due to the repressurization of the magma reservoir beneath Mount St. Helens, caused by the arrival of additional magma 2.5 to 5 miles beneath the surface.

Is it true or false that mantle material rises in convection currents because heated materials become more dense? Heated materials generally become less dense. In the Earth hot material from the mantle rises at hotspots (though this hypothesis is disputed). The cause of convection is also disputed, either it is top down - cool downgoing plates drag mantle material down driving convection, or the hot, liquid outer core releases heat into the mantle and drives convection by heating from the bottom.

Uplift crust floor sea north. Uplift is the process by which the earth's surface slowly rises either due to increasing upward force applied from below or decreasing downward force (weight) from above. During uplift, land, as well as the sea floor, rises. The outer shell of the earth, the crust, divides into moving sections called plates.

Convection Currents Convection currents 3. The continuous cycle of magma rising and falling in the Earth's mantle is called a Convection current. The movement of magma causes friction between the tectonic plates. This friction causes the plates to move. The movement of the plates causes events like volcanic erruptions, earthquakes and tsunamis.

- The gravity causes this movement down the ridge, and it gives the plate a push along as new crust forms behind the plate at the spreading center. This is like those coin bulldozers at the fair where one new coin may push forward and knock others out of the way!

What force causes warm molten rock to move upward to the mantle? exists and is an alternate of. Merge this question into. Split and merge into it. Answered by The Community. Making the world better, one answer at a time. The force that causes warm molten rock to move upward to the mantle is called convection. Convection happens when parts of the tectonic plate break off and melt.

Tectonic Plate Motion The formation of volcanoes is a result of the subduction of the oceanic crust. As the oceanic crust gets forced deeper into the Earth the increasing heat and pressure releases trapped water and gases, the combing effect of which is the crust melting to form magma.
