During a volcanic eruption or on a constructive boundary
What else can I help you with?
The opening in Earth's crust through which magma rises to the surface is known as the?
The opening in the earth crust which magma rise to the surface are Volcanoes
What must happen first before magma rise to the surface?
Before magma can rise to the surface, it must first be generated through melting of the Earth's mantle or crust. This melting can be caused by an increase in temperature, a decrease in pressure, or the addition of volatiles. Once magma is generated, it can rise towards the surface through fractures and conduits in the Earth's crust.
Which of the Earth's layers does the magma come?
Magma is fluid molten rock that exists under the Earth's crust.
Why do magma's rise toward the earth's surface?
Rocks become less dense when they melt
How volcanoes occur?
Volcanoes occur when the earth cools off, and releases internal heat and pressure. Magma is a lower density than the surrounding rocks, and this causes it to rise to the surface. As it rises, gas bubbles form in the magma, exerting pressure, causing the magma to erupt out of the surface of the earth.
Where might magma rise to earth surface?
Near the tech-tonic plates of the earth.
Why does magma from deep inside Earth rise toward the surface?
cuz
What rock that melts underneath earth?
The rock that melts underneath the Earth is called magma. Magma is formed from the melting of the Earth's mantle and can rise to the surface to form igneous rocks when it solidifies.
The opening in Earth's crust through which magma rises to the surface is known as the?
The opening in the earth crust which magma rise to the surface are Volcanoes
Why does magma in a volcano rise up to Earth's surface?
Magma rises because it is less dense than the rock around it.
What must happen first before magma rise to the surface?

Which of the Earth's layers does the magma come?
Magma is fluid molten rock that exists under the Earth's crust.
How does magma rise to the surface of the Earth?
Through cracks, holes or vents in the earths crust.
Why does magma deep inside the earth rise toward the surface?
because of the high pressure
Why do magma's rise toward the earth's surface?
Rocks become less dense when they melt
How volcanoes occur?
Volcanoes occur when the earth cools off, and releases internal heat and pressure. Magma is a lower density than the surrounding rocks, and this causes it to rise to the surface. As it rises, gas bubbles form in the magma, exerting pressure, causing the magma to erupt out of the surface of the earth.
How does magma move from a chamber deep within earth to earth surface?
this answer has to do with density if magma becomes less dense than rock it will rise to the top ,for example vegetable oil in water.
