What happens to magma when two oceanic plates move apart?

What happens to magma when two oceanic plates move apart?

As plates made of oceanic crust pull apart, a crack in the ocean floor appears. Magma then oozes up from the mantle to fill in the space between the plates, forming a raised ridge called a mid-ocean ridge. The magma also spreads outward, forming new ocean floor and new oceanic crust.

What Happens When ocean plates move apart from each other?

When two plates move away from each other they create a divergent boundary. When this happens under oceans, new ocean floor is created. When two plates move away from each other they create a divergent boundary. When this happens under oceans, new ocean floor is created.

What happens when magma rises and pushes plates apart?

When the plates move they collide or spread apart allowing the very hot molten material called lava to escape from the mantle. When collisions occur they produce mountains, deep underwater valleys called trenches, and volcanoes. The bottom of the Atlantic Ocean is filled with some of the “youngest” crust on Earth.

What happens when the Earth’s plates move apart?

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.

What forces magma beneath to move?

Cause of volcano tectonic earthquakes The compression of plates at these subduction zones forces the magma beneath them to move. Magma can not move through the newly compressed crust in as easily a manner. This means it tends to pool in magma chambers beneath the surface and between the converging tectonic plates.

What happens when two plates move away from each other?

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. When two plates come together, it is known as a convergent boundary. Where do lithospheric plates move?

How does the oceanic crust form according to plate tectonics?

According to plate tectonics, oceanic crust forms from upwelling magma that spreads outward from a mid-ocean ridge. Which of the following support this?

What happens when tectonic plates converge in a subduction zone?

Where tectonic plates converge, the one with dense, thin oceanic crust subducts beneath the one with thick, more buoyant continental crust. An accretionary wedge forms between the converging plates as material is scraped off the subducting plate.

What happens when a plate boundary is divergent?

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.
