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 the mantle rise through the crust above it?
magma comes from the outer core and when an earthquake or something happends, a crack froms and the pressure of lava shoots up like a geyser.
Is magma released from volcanoes material from the core?
No, magma is not material from the core of the Earth. Magma is molten rock that is generated in the Earth's mantle, which lies between the core and the crust. Magma can rise to the surface during volcanic eruptions, forming lava flows or erupting explosively.
How is plate subduction connected to the formation of volcanoes?
When the plate subducts, the crust is destroyed and turned into magma. Some of this magma may rise and come through the crust. When it hits the sea floor, it cools down and turns into solid rock. This can keep on building up until it hits the surface.
Why are igneous rock formed?
They can be formed underground or above ground. Underground, they are formed when melted rock, called magma, deep under the earth's surface is trapped in small pockets. As these pockets of magma cool slowly underground, the magma develops into igneous rocks. Igneous rocks are also formed when volcanoes erupt, causing the magma to rise above the earth's crust. When magma appears above the earth, it is called lava. Igneous rocks are formed as the lava cools above ground.
Why does magma rise to the crust above it?
Magma rises through the crust above it because of pressure and depending on the magma (Pahoehoe or Aa). Pahoehoe is thin and runny and pours outside of the crust but, Aa is think and chunky and it can not pour out of a crack in the crust. It is more likely to blow out.

How does magma rise to the surface of the Earth?
Through cracks, holes or vents in the earths crust.
Large areas which have elevated domes are formed by what?
Granite magma attempting to rise through the crust.
What causes a magma chamber to rise?
Magma rises through the crust because it is less dense than the surrounding rock, and due to the enormous pressure inside the earth.
How is granate made?
Granite is made from the melting of the lower crust. As these magma domes slowly rise through the crust toward the surface, some may solidify underground. This solidified material is called granite.
Is magma released from volcanoes material from the core?
No, magma is not material from the core of the Earth. Magma is molten rock that is generated in the Earth's mantle, which lies between the core and the crust. Magma can rise to the surface during volcanic eruptions, forming lava flows or erupting explosively.

Why does magma rise through the crust above it in an erupting volcano?
The Earth's internal pressures force magma to the surface in areas of weakness , or sometimes faults.
What causes the magma to rise and push the underside of the oceanic crust at the mid-ocean ridge?
As with most Magma uprising, it is caused by internal pressures of the Earth.
