No. Magma is heated rock, and under great pressure. So if a conduit opens, it may enter a rock chamber beneath the surface, cool, and solidify there. Or it may exit a vent on the ocean floor, building new seafloor. A formation of solidified magma as igneous rock within the mantle is called a pluton.
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.
Magma is molten rock beneath the Earth's surface, while lava is magma that reaches the surface through a volcano or fissure. So, while all lava was once magma, not all magma will reach the surface as lava.
'Magma' while it is still in or below the Earth's surface and when it reaches or flows out on the Earth's surface it is called 'lava'. Magma from the 'magma' chamber can form a 'lava lake' at the surface and the lake can drain down the volcano in 'lava tubes' to form 'lava flows' or 'pillow lavas' if the lava tubes drain into the sea.
There are almost no extrusive rocks on the earths surface because they are all under the earths surface. They are mainly lower than the earths surface.
No, not all igneous rock is formed from lava that cooled on Earth's surface. Some igneous rocks are formed from magma that cooled below the surface, and these are called intrusive igneous rocks. These rocks cool more slowly than lava, allowing for larger mineral crystals to form.

No! First of all, magma is below the surface and it is molten material.

No. Along its path to the surface, most magma is stopped short by gradual cooling and solidification at a point below the surface.

Yes it does because where else would it come from.

Pocket of magma beneath the surface
All of the atmospheric gases can be found trapped in magma and solidified rock.
