Lava is magma that has reached the surface.
Lava ;D
Extrusive Volcanism
Magma is the term applied to molten rock beneath the surface of the earth. It is formed when hot (very hot) rocks experience a drop in surrounding pressure, or when subducted wet lithosphere is introduced into the mantle. When it "breaks out" onto the surface of the earth, we call it lava. A link can be found below.
The size of the mineral crystals in an igneous rock is related to the rate of time spent in cooling from magma. Longer exposure to the crystallization temperature means larger crystals. Less time means smaller crystals, or in the case of obsidian, which cools extremely quickly, no crystallization.
Yes they do
When magma erupts onto the planet's surface, it is called lava.
Molten rock is known as Magma when underground and has not yet been erupted onto the surface.
the magma chamber and then they erupted onto the surface, where the small crystals were formed.
Magma that has come to the surface is then referred to as Lava.
Lava. Because when magma reaches the surface, it is called lava.
Magma that flows onto Earth's surface is called lava.
Lava
It is then called lava.
Magma that flows onto Earth's surface is called lava.
it is called lava
Magma that reaches the Earth's surface is known as lava.
When lava is underground, it is called magma. Magma is molten rock beneath the Earth's surface that can eventually erupt onto the surface as lava during a volcanic eruption.
