Magma is usually associated with volcanic activity, but in the deep trenches of the oceans seepage of magma is the cause of continental drift in a small but relentless way. The tectonic plates boundaries on land are where mountains are formed and where most volcanoes and earthquakes occur.

How is convection in the mantle related to the movements of the tectonic plates?
because it moves the crust
How magma moves upward though a volcano and reaches the surface during an eruption?
The inside of the earth (Mantle) pushes the hot magma liquid and makes the magma move toward the surface.
How do you briefly explain how volcanoes that are located in hot spots formed?
As tectonic plate moves over a mantle plume, rising magma causes a chain of volcanic islands to form.
What happens when oceanic and continental crust meets?
Subduction. denser oceanic plate moves under the continental plate. The oceanic plate is submerged into the mantle causing magma to rise to the surface.
What is the driving force of plate tectonics'?
That force is caused by the convection currents in the magma below the plates.
How can mantle flow because its made of hot liquid magma?
Magma in the mantle moves in a current called a convection current. A convection current is a circular flow of a substance in which a hot substance rises, cools, sinks, gets hot again, and repeats. In this way, magma in the mantle flows in currents of more hot or more cool magma.
How is convection in the mantle related to the movements of the tectonic plates?
because it moves the crust
Where does magma form before it moves toward the earths surface?
in the mantle above the slab
How magma moves upward though a volcano and reaches the surface during an eruption?
The inside of the earth (Mantle) pushes the hot magma liquid and makes the magma move toward the surface.
What part of the earths mantle that flows and moves the plates of the earth?
Mantle plumes are in the mantle, BELOW the Earth's crust. The circulation of heat from the lower mantle to the upper mantle can cause "hot spots" in the overlying crust, heating the magma in the areas.
The layer between earth's core and its crust is called?
There is no layer of melted rock directly below the Earth's crust. The upper mantle is composed of solid, but flexible rock which is prevented from melting by the pressure of surrounding material.
What are forms of a magma?
the mantle (2nd and thickest layer of the earth) has a lot of squishy extreamly hot rocks and sometimes the mantle gets too hot which makes some ocks melt and there getss so much precier that it has to go. then it moves torward the earths surfice. after years and years and years the magma builds up to the top of the volcano and there is so much preacure it lets go and then the magma is called lava
When the earth plates move apart what happens?
when two plate moves apart from each other the intrusion of magma has been take place from mantle
What are convection current and how are they formed?
Convection currents in the earth originate in the mantle. The liquid moves in a circle pattern as the hotter magma rises and the cooler magma falls. This can also be observed in any fluid material, gases or liquids.
What moves on a plasticlike layer of the mantle?
The crust moves on a plastic like layer of the mantle.
What moves a plasticlike layer of the mantle?
The crust moves on a plastic like layer of the mantle.
