What else can I help you with?
Does all magma come from the earths core?
No, not all magma comes from the Earth's core. Magma can also originate from the mantle, which is the layer beneath the Earth's crust. The heat and pressure from the mantle can cause rocks to melt and form magma, which can then rise to the surface as volcanic eruptions.
Does all magma come from earths core?
Yes it does because where else would it come from.
Why does magma come to the surface?
Magma is less dense than the surrounding rock; as such, it will rise toward the surface.
Is. magma is melt rock that has come to the surface?
No! First of all, magma is below the surface and it is molten material.
When does magma become lava?
It should be magma is the hottest because it is usually molten rock that has not reached the surface during an eruption.Lava is 2nd hottest. It is the molten rock we see when a crack in the crust of the earth or a volcano eruption allows molten rock from beneath the crust to come up.
Where is a weak spot in the crust where magma has come to the surface?
A Volcano.
What are melted rocks called and where do they come from?
Magma is melted rock that is found beneath the surface of the earth.It is called magma
What is it called when Magma that is extruded onto the surface either beneath water or air?
Magma that has come to the surface is then referred to as Lava.
What are melted rocks called when they come to the surface?
Lava. (When it is underground it is called magma)
How do earthquakes and volcanoes transfer energy from earth's interior to the surface?
During a volcano eruption, theheat energy is transferred through lava to the surface of Earth. The magma may come up to the surface as magma bringing heat energy to the surface.
What is igneas rock origin?
Igneous rocks form from the cooling and solidification of magma or lava. Magma, which is molten rock beneath the Earth's surface, can rise due to pressure and temperature changes, eventually cooling and solidifying to form igneous rocks. These rocks can be classified as intrusive (formed below the surface) or extrusive (formed on the surface).
Does magma equals lava?
Lava and magma are both substances produced by volcanoes. There is a difference between the two, however. Specifically, magma has not yet come out of a volcano, while lava is magma that has erupted out of the cone.
