Magma rises to the Earth's surface through volcanic eruptions via conduit or lava channels within the Earth's crust. The buoyant force of the magma, caused by the difference in density between the magma and surrounding rocks, helps drive its upward movement. As the magma rises, it can also accumulate in magma chambers beneath the surface before erupting as lava.

The opening in Earth's crust through which magma rises to the surface is known as the?
The opening in Earth's crust through which magma rises to the surface is known as a volcano.
What is the molten rock found beneath the surface of the earth?
The molten rock found beneath the surface of the Earth is called magma. Magma forms in the Earth's mantle and can rise to the surface during volcanic eruptions, where it is then known as lava.
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.
How volcanoes occur?
Volcanoes occur when magma from within the Earth's mantle rises to the surface, creating pressure that eventually leads to an eruption. The magma can come from melting of the Earth's crust or mantle. When the pressure becomes too great, the magma breaks through the Earth's surface, forming a volcano.
Why do magma's rise toward the earth's surface?
Rocks become less dense when they melt

Why does magma from deep inside Earth rise toward the surface?
cuz
Where might magma rise to earth surface?
Near the tech-tonic plates of the earth.

Melted rock that is beneath Earth's surface?
Melted rock beneath Earth's surface is known as magma. Magma forms in the Earth's mantle and can rise to the surface, where it is then called lava. Magma can also cool and solidify beneath the surface, forming igneous rocks.

When the pressure becomes too great, the magma breaks through the Earth's surface, forming a volcano.
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
Why does magma in a volcano rise up to Earth's surface?
Magma rises because it is less dense than the rock around it.
Magma tends to rise toward earths surface?
Magma rises towards the Earth's surface due to differences in density between the magma and surrounding rock, as well as pressure changes. This movement can eventually lead to volcanic eruptions.
