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 causes magma beneath the volcano to rise to the surface?
Increasing pressure pushes the magma upwards. This rising pressure can be caused by many different things.
Will the sea drain away in an underwater volcanic eruption?
No, because as the magma rises from underwater volcanoes it heats the water causing it to rise. The magma then solidifies. Therefore when the volcano is active it is always heating the water around it. When the magma stops flowing then the volcano will solidify.
How are volcanes made?
Magma Chambers allow the oceanic plate to rise in the form of of a volcano with no testicles 8===D
Is lava magma?
yes. magma is the lava that is in the volcano and lava is the magma that is outside a volcano
What causes the magma inside a volcano to rise to award the surface?
The molten magma increases in pressure (like a pressure cooker at home) until it is forced towards the surface.
Where is the magma in a volcano?
In a magma chamber
What happens before the eruption of the Kilauea volcano?
When the magma gets close to the surface, the gases dissolved in it start to come out, forming gases which help the magma rise further and erupt. If there is a lot of gas in the magma, it may explode as the gases expand. There may also be triggers like a landslide that uncaps the magma reservoir (like at Mt. St. Helens in 1980) or an interaction with groundwater that causes an explosion.
How are volcanic cones made?
Magma Chambers allow the oceanic plate to rise in the form of of a volcano with no testicles 8===D
What is magma calle when it comes out of a volcano?
When magma comes out of a volcano, it is called Lava.
Where on magma is the mage on HorseIsle?
mage=volcano on magma keep going around volcano
Is lava in the magma?
Lava is when it's outside the volcano, magma is when it's inside of the volcano.
