When magma reaches the surface what happens to the gases?
The gasses bubble out of the magma, sometimes explosively.
What is the name when magma reaches the surface?
Magma is liquid rock before it reaches the surface magma which reaches the surface is called lava.
What is the magma when it reaches the earths surface?
Magma that reaches the Earth's surface is known as lava.
What magma is called when it reaches the surface?
Magma that reaches the Earth's surface is known as lava.
When magma reaches the surface its dissolved gas content increases True or False?
False! The reduction in pressure causes the gasses to exsolve (come out of solution) and escape into the atmosphere, so the dissolved gas content of a magma reduces when it reaches the surface.
How will stiff magma create an explosive eruption?
The more viscous or "stiff" types of magma usually contain more trapped gasses. When the magma reaches lower pressure near the surface, the gasses expand explosively, blasting ash and pumice into the air.
Magma that reaches the earths surface?
Magma that reaches earth's surface is called lava.
What is magma called when it reaches the earth's surface?
Magma that reaches the Earth's surface is known as lava.
Why doesn't granite have airholes?
Granite is formed from magma, not lava. And, no, they are not the same thing. Magma is inside of the Earth, but lava is what you get after the magma reaches Earth's surface and gasses within it expand when the pressure is deduced.
Before molten rock reaches the surface it is called what?
Before lava reaches the surface it is called magma.
What is molten rock (magma) called when it reaches the earth's surface?
Magma is called lava when it reaches the surface.
Does a volcano form when magma reaches earths surface?
That is correct. When magma travels from the mantle to the crust and reaches the surface, that is a volcano.
