They are called Plutons, or plutonic igneous rocks, and are known as intrusive igneous rocks also.

What would have larger crystals igneous rock that formed below earths surface or above?
below
Is it true that extrusive rocks are formed if the solidification of magma occurs inside the earth?
No. Extrusive igneous rock is formed at or near the surface from rapid cooling. Intrusive igneous rock is formed below the surface from slow cooling of magma.
What do intrusive rock have in common with extrusive rocks?
Sedimentary rocks are not classified by the terms intrusive or extrusive. These are terms used specifically for igneous rock classification, referring to rock that has formed from melt either below or on the surface.
How do rocks that are formed deep below the earth's crust get to the surface?
lifting due to tectonic forces then erosion for the majority, but a few rare ones are blasted directly from the mantle where they formed via kimberlite pipes.
What are 2 basic classifications of Igneous rock?
The two types of igneous rock are are intrusive and extrusive, depending on where they form. Intrusive igneous rock forms underground from slow cooling magma. Extrusive igneous rock forms at or near the surface from quick cooling lava.
What is a volcano eruption?
A volcano is an opening, or rupture, in the planet's surface or crust, which allows hot magma, volcanic ash and gases to escape from below the surface.
Do all volcanoes have diamonds?
No volcano produces diamonds. Diamonds are erupted to the surface of the earth through volcanic pipes, which look like upside-down volcanoes. These pipes erupt indicator minerals, some of which include diamonds.
How are rocks formed in a volcanic eruption?
They are formed when the erupted magma or lava, cool and sollidifies below or above the earths surface respectively.
What is lava magma and crater?
Molten rock below the surface of the earth that rises in volcanic vents is known as magma,but after it erupts from a volcano its called lava and a crater is the hole of a volcano.
How do you know if a volcanic eruption will be quiet or explosive?
A volcano is an opening, or rupture, in a planet's surface or crust, which allows hot magma, volcanic ash and gases to escape from below the surface. So expect explosions and a lot of noise.
How are crystals formed and how does the rate effect the crystal?
Crystals that are formed below the surface are formed by the cooling of magma. Crystals above the surface are formed when a volcano erupts, and cools, again, above the surface. Crystals that are below the surface usually have a slower rate of cooling than those above the surface, causing bigger crystals because of the slower cooling:)
Do diamond and obsidian have anything in common?
Yes, both are formed in the earth, both are considered 'rocks' and both have translucent properties. Obsidian is glass that results from volcanic eruptions; diamonds are erupted to the earth's surface from volcanic pipes. Pipes are shaped like volcanoes, both with bases at the earth surface. The tip of a volcanic pipe is far below the earth surface: volcano tips soar into the earth's atmosphere. Both form crystals, but with different structures. Obsidian is formed from felsic lava "...which is high in silica, aluminium, potassium, sodium, and calcium..." and diamonds are formed from carbon.
What is avolcano?
A volcano is a geological structure formed by the eruption of molten rock, ash, and gases from the Earth's crust. It is often cone-shaped and has a vent or opening through which the material is expelled. Volcanoes can be found on land or underwater.
How are geothermal pools formed?
Geothermal pools are formed where the hot rocks below the surface of the earth are close enough to warm pools of water on the surface. Areas of volcanic activity typically have hot springs, as in the North Island of New Zealand.
Is a diamond sedimentary rock?
No. By definition, sedimentary rock is formed on the earth's surface and in bodies of water. Diamonds are formed far below the earth's surface and are erupted to the surface by way of volcanic pipes.
Is a sedimentary rock formed below earth's surface as magma?
No. A rock formed below earth's surface as magma is an igneous rock.
What is the difference between plutonic rocks and volcanic rocks?
Both are igneous rocks, but whereas volcanic rocks are formed from cooling lava on the surface, plutonic rocks are formed from cooling magma below the surface. So plutonic rock is an igneous intrusive rock, while volcanic rock is extrusive.
