YOUR A DUMBO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I AM GOING TO TELL MY FRIENDS TO NOT USE WIKI USER BECAUSE I AM TRYING TO SEARCH UP SOMETHING AND YOU ARE MAKING JOKES
The opening in the earth crust which magma rise to the surface are Volcanoes
When magma breaks through the Earth's crust, it is referred to as a "volcano." Specifically, the term "vent" is used to describe the opening through which the magma, now called lava when it erupts, escapes. The entire geological structure formed as a result of this eruption is also known as a volcanic cone or a volcano.

Igneous Rock
Magma is fluid molten rock that exists under the Earth's crust.
Molten rocks called Magma.
The movement of magma through the Earth's crust is known as intrusion.

The entire geological structure formed as a result of this eruption is also known as a volcanic cone or a volcano.
Magma typically forms in the Earth's mantle, which is a layer beneath the crust. It forms as a result of the melting of rocks due to high temperature and pressure within the mantle. This molten rock can then rise to the surface through volcanic activity.
lava
lava
Magma is formed deep within the Earth's mantle due to high temperatures and pressure. When magma rises towards the Earth's crust, it does so through fractures or weaknesses in the crust, driven by buoyancy forces. As it ascends, it can create volcanic activity through eruptions or intrusions into the crust.
Igneous Rock
Magma is fluid molten rock that exists under the Earth's crust.
Pressure inside the earth forces the magma through cracks and other conduits in earth's crust.
Magma from the mantle of the earth is forced up through fissures in the crust of the earth.
