What crustal feature is a result of divergent plate movement?
A mid-ocean ridge is a crustal feature formed by divergent plate movement. This occurs when tectonic plates move apart, allowing magma to rise to the surface, creating new oceanic crust.
What is any movement of magma inside earth?
Any movement of magma inside the Earth is called magma migration. Magma migrates due to differences in pressure, density, and temperature within the Earth's mantle, moving towards the crust through fissures or fractures. This movement can lead to volcanic activity when the magma reaches the surface.
What type of magma causes quiet eruption?
Magma with low viscosity, such as basaltic magma, typically causes quiet eruptions. This type of magma flows easily and allows gases to escape, resulting in relatively gentle eruptions with less explosive activity.
Why movement of crustal plates depend on heat?
The movement of crustal plates is driven by the flow of semi-molten rock in the mantle caused by heat from Earth's core. This process, known as mantle convection, creates thermal gradients that move the plates above. Heat is the primary energy source driving the tectonic plate movements that lead to phenomena such as earthquakes and volcanic eruptions.
How can magma under the surface create seismic tremors?
There are two main ways magma causes tremors. First, as it is forced along under pressure the magma causes the rock around it to fracture. Tremors occur as these fractures form. Also, when magma moves through a conduit it creates vibrations, much in the same way that air moving through a wind instrument creates sound.
What causes volcanic activity to occur?
Volcanic activity occurs when molten rock, called magma, rises to the surface of the Earth through cracks in the crust. This can happen due to the movement of tectonic plates, which can create pressure and heat that forces the magma to erupt as lava, ash, and gases.

A mid-ocean ridge is a crustal feature formed by divergent plate movement. This occurs when tectonic plates move apart, allowing magma to rise to the surface, creating new oceanic crust.
Any activity that icludes the movement of magma on to the earth's surface?
This is known as a volcanic eruption.
What is the cause of the Italian earthquake 2009?
All earthquakes have the same cause, which is the movement of the Earth's crustal plates resulting from convection currents in the magma upon which they float.
What causes small earthquakes before a volcanic eruption?
The earthquakes are caused by the movement of magma underground and the breaking of rocks by that magma.
This is not included in the three major zones of crustal movement.?

What does most Most magma form from?
Magma is the result of partial melting of crustal rocks. It is a eutectic melt product.

Heat is the primary energy source driving the tectonic plate movements that lead to phenomena such as earthquakes and volcanic eruptions.
How can earthquakes be used to show evidence of volcanic activity?
Earthquakes can indicate volcanic activity because magma moving beneath the Earth's surface can generate seismic activity. As magma rises and interacts with the surrounding rock, it can create pressure and stress that lead to earthquakes. By monitoring the location and intensity of these earthquakes, scientists can infer the movement of magma and potential volcanic activity.
