Plutonic rocks are formed by magma hardening underground. Sometimes they get pushed up to the surface. Stone Mountain in Georgia is plutonic. Volcanic rock forms when lava hardens on the surface, not underground. Some volcanoes are built up in this way.
Igneous rock is formed through the cooling and solidification of magma or lava. Igneous rock may form with or without crystallization, either below the surface as intrusive(plutonic) rocks or on the surface as extrusive (volcanic) rocks. This magma can be derived from partial melts of pre-existing rocks in either a planet's mantle or crust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Over 700 types of igneous rocks have been described, most of them having formed beneath the surface of Earth's crust. These have diverse properties, depending on their composition and how they were formed.
Intrusive igneous rocks (plutonic) are formed from magma that cools and solidifies within the crust of a planet. Surrounded by pre-existing rock (called country rock), the magma cools slowly, and as a result these rocks are coarse grained.
Extrusive igneous rocks (volcanic) are formed at the crust's surface as a result of the partial melting of rocks within the mantle and crust. Extrusive Igneous rocks cool and solidify quicker than intrusive igneous rocks. Since the rocks cool very quickly, they are fine grained.
Plutonic rocks are formed by the inside of the volcano through slow cooling of magma.
Molten rock forms in the upper portions of Earth's mantle.
plutonic rocks are formed underground.
volcanos
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.
Plutonic activity is another term of volcanic activity. Plutonism is a geologic theory that states the rocks that form the planet Earth were formed through volcanic activity.
A hypabyssal igneous rock is formed in between the depth of intrusive (also called plutonic) rocks and extrusive (volcanic) rocks. They are formed when magma or lava cools down and solidifies.
you can find it in any geographic region that is characterized by volcanic and plutonic rocks formed from magma of basaltic composition.mostly in eastern asia
grandnodiorite is it plutonic or volcanic

No. Volcanic rocks are extrusive. Intrusive rocks are sometimes called plutonic.
those formed deep into the earth are called Intrusive or Plutonic rocks,those formed ator near thesurface are called Extrusive or volcanic rocks
They are both igneous rocks.
No. Plutonic rocks are igneous rocks that hardened underground. Rocks that form on volcanoes are volcanic rocks.
A hypabyssal igneous rock is formed in between the depth of intrusive (also called plutonic) rocks and extrusive (volcanic) rocks. They are formed when magma or lava cools down and solidifies.
They are called Plutons, or plutonic igneous rocks, and are known as intrusive igneous rocks also.
Plutonic rock is formed from magma in the Earth's crust. Volcanic rocks form from lava above ground.
Metamorphic, along with volcanic and plutonic igneous rocks.
the large plutonic rocks formed by the hardening of magma into the earths crust is called the ignius rocks
you can find it in any geographic region that is characterized by volcanic and plutonic rocks formed from magma of basaltic composition.mostly in eastern asia
