What else can I help you with?
If each island formed as the crustal plate moved over the magma source in the mantle as shown in diagram II where would the next volcanic island most likely form?
The next volcanic island would most likely form to the southeast of the existing islands, following the direction of the crustal plate movement over the magma source in the mantle. As the plate continues to shift, it will expose new areas above the magma hotspot, resulting in volcanic activity and the formation of an island in that region.
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.
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.

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.
Any activity that icludes the movement of magma on to the earth's surface?
This is known as a volcanic eruption.
This is not included in the three major zones of crustal movement.?
Mariana Trench
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.

Volcanism that allows magma to seep into the crustal layers and harden?
internal
What does most Most magma form from?
Magma is the result of partial melting of crustal rocks. It is a eutectic melt product.

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.
