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.
These movements are called mantle convection. It involves the circulation of molten rock (magma) in the Earth's mantle due to heat from the core causing hot material to rise and cooler material to sink, creating a circular motion.
The movement of magma in the earth's crust resulting in changes in the crust is called magmatism. During this occurrence is when igneous rocks like mountains form.

What is the liquid rock in the mantle called?
The liquid rock in the mantle is called magma. As it moves closer to the surface, it is then called lava when it erupts from a volcano.
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 Produced as a plate moves deeper into the mantle?
As a tectonic plate moves deeper into the mantle, it experiences increased pressure and temperature. This can lead to the plate melting partially or completely, forming magma. The magma produced can then rise to the surface through volcanic activity, leading to the formation of volcanoes and igneous rocks.
Magma flows in the mantle like a river and can form magma pools?
Magma flows in the mantle due to its high temperature and lower density compared to the surrounding rock, but it moves much more slowly than water in a river. As magma rises towards the surface, it can accumulate in magma chambers or pools before erupting as lava onto the Earth's surface.
What process makes new crust when the sea floor moves apart and magma rises up?
The process that makes new crust when the sea floor moves apart and magma rises up is called seafloor spreading. Magma from the mantle rises to the surface at mid-ocean ridges, cools, and solidifies to form new crust as the tectonic plates move apart. This process contributes to the continuous growth of the seafloor and the expansion of the ocean basins.
What is the liquid rock in the mantle called?
The liquid rock in the mantle is called magma. As it moves closer to the surface, it is then called lava when it erupts from a volcano.
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.
Where does magma form before it moves toward the earths surface?
in the mantle above the slab

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.
Magma flows in the mantle like a river and can form magma pools?
Magma flows in the mantle due to its high temperature and lower density compared to the surrounding rock, but it moves much more slowly than water in a river. As magma rises towards the surface, it can accumulate in magma chambers or pools before erupting as lava onto the Earth's surface.
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
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 type of boundary moves away from each other allowing magma to create new ocean crust?
A divergent boundary moves away from each other, allowing magma from the mantle to rise and create new ocean crust through volcanic activity. This process is called seafloor spreading and occurs along mid-ocean ridges.
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.
