What else can I help you with?
Where is a weak spot in the crust where magma has come to the surface?
A Volcano.
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.
Why does magma come pouring out onto the earths surface?
It pours onto the surface because it wants to.
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.
What is the name of the opening in the earths crust where hot melted rocks from inside the earth come to the surface?
volcano
WHEN MAGMA reachesthe surfacegases out of it?
Yes, gases do come out and then the magma under the Earth's crust.
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).
What is the name of opening in the earths crust where hot melted rocks from inside the earth come to the surface?
The opening in the Earth's crust where hot melted rocks from inside the Earth come to the surface is known as a volcano. When pressure builds up beneath the Earth's surface, it can lead to volcanic eruptions, where magma, ash, and gases are expelled. Volcanoes can vary in size and activity levels, with some being constantly active while others remain dormant for long periods.
What is the weak spot in the crust where magma has to come up?
Volcano
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.
