Extrusive igneous rock.
well, it does. haven't you ever heard of hot lava? that's magma rising from the surface.
You're thinking of magma.
magma
I think igneous rock have a larger crystal than all the others because igneous rock is all the way at the bottom of earth surface and it keeps cool of or hot at the same time.
Magma.
A natural hot melt composed of a solution of rock-forming materials, steam, and super-heated gases from which igneous rock results.
its just lava when it reaches earth's serface, its magma when its still inside Molten rock on the surface is called lava. It is cooler than magma, and quickly becomes solid. This is because it is much cooler on the earths surface than inside the earth. As magma rises it starts to cool, as you go up the volcano it gets cooler by 15 degrees every 1 km. so when the magma gets to the top of the volcano it is cooled down quite a bit and turns into lava
Mid Atlantic ridge or north atlantic ridge
Lava is molten rock that erupts onto the Earth's surface, while magma is molten rock beneath the surface. The temperature and pressure difference between them affect their behavior and appearance. Lava typically flows more fluidly, while magma can be trapped underground in magma chambers.
The molten rock inside the Earth is called magma. When magma reaches the surface, it is called lava.
Magma .
A hot spot is formed on a point of the earths surface where strong upward convection currents or plumes of hot magma in the upper mantle push up below the plates of the lithosphere causing volcanic activity. no it doesn'twhen the mantle is weak
