How does the magma rise from the volcano?
magma rises up out of a volcano by the build up of pressure
Why does magma in a volcano rise up to Earth's surface?
Magma rises because it is less dense than the rock around it.
What could rise up through the gaps between the plates?
molten rock or magma
How does magma rise to earth surface?
it is pushed up by becoming extremely hot and rises and becomes lava
What causes magma to flow upward thought the earths surface?
The tectonic plates push together thus causing magma to shoot up and rise hence an eruption
Why magma rise soon after it forms?
It is because of the steam. It will help to push it up and make it almost float to the top.
What forms at mid oceanic ridges?
i think its uprising magma wen it rise up, it makes the divergence marginthat would cause mid oceanic ridge
What causes magma to rise to earths surface?
The magma is in the mantle, the layer under the crust. There is a convection current caused by radioactivity in the inner core which causes the plates to move. Therefore the constructive plates move apart which means magma can rise up. It'll then solidify and this is what makes volcanoes. Hence CONSTRUCTive.
Does heated magma rise or sink?
When magma is being heated it rises. When it is cooled, it sinks.
Where does magma mainly rise to the surface?
at volcanoes
Why does magma rise soon after form?
It is because of the steam. It will help to push it up and make it almost float to the top.
Why does the newly formed magma at divergent plate boundaries rise to the surface?
Interior pressure of the forces the magma through the crack. This upwelling of magma then rapidly cools and becomes brittle as it hardens. The pressure of the subsurface magma then breaks this brittle rock and forces more magma up in a continuous cycle.
