Differbetween
The two main types of igneous rocks are plutonic rocks and volcanic rocks. Plutonic rocks are formed when magma cools and solidifies underground. Volcanic rocks are formed from lava that flows on the surface of the Earth and other planets and then cools and solidifies.

What is the difference between the two types of igneous rocks?
The two main categories of igneous rocks are extrusive and intrusive. Extrusive rocks are formed on the surface of the Earth from lava, which is magma that has emerged from underground. Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet.
What's the difference between intrusive plutonic and extrusive volcanic igneous rocks?
What is the difference between volcanic and plutonic igneous rocks? ... Intrusive,plutonic rocks are generally coarse grained. Extrusive volcanic rocks tend to be fine grained to glassy. You just studied 12 terms!
What is a plutonic rock?
Intrusive rock, also called plutonic rock, igneous rock formed from magma forced into older rocks at depths within the Earth's crust, which then slowly solidifies below the Earth's surface, though it may later be exposed by erosion. ...
How and why do the textures of volcanic rocks differ from the textures of plutonic rocks?
Volcanic rocks and plutonic rocks differ mainly in that volcanic rocks form at the surface of a planet whereas plutonic rocks form beneath the surface. Plutonic rocks are also coarser grained, being made of large interlocking crystals whereas volcanic rocks are more fine-grained.
What are the 2 main types of igneous rocks?
Igneous rocks are divided into two groups, intrusive or extrusive, depending upon where the molten rock solidifies. Intrusive Igneous Rocks: Intrusive, or plutonic, igneous rock forms when magma is trapped deep inside the Earth.
What are the two main types of metamorphic rock?
There are two main types of metamorphic rocks: those that are foliated because they have formed in an environment with either directed pressure or shear stress, and those that are not foliated because they have formed in an environment without directed pressure or relatively near the surface with very little pressure ...
Is the example of plutonic rock?
Plutonic rocks (plutonites) cover the compositional range from acidic through intermediate and basic to ultrabasic, with granite, granodiorite, syenite, diorite, gabbro and peridotite as examples (see Plutonic rocks—classification and nomenclature).
What are the 3 types of volcanic rock?
Professor Richard Price introduces some of the common types of volcanic rocks and talks about how they are used to study volcanoes.
- Igneous rocks. Rocks are broadly classified into three groups – igneous, sedimentary and metamorphic. ...
- Lava solidifies to rock. ...
- Basalt. ...
- Andesite. ...
- Rhyolite.
Is granite plutonic or volcanic?
Basalt and obsidian are volcanic rocks; granite is plutonic. Ask students how they can determine this. The answer is: plutonic rocks (such as granite) cool slowly in a relatively undisturbed environment permitting the growth of large mineral crystals which can easily be seen by the unaided eye.
What is the characteristics of plutonic rocks?
It cools slowly (tens of thousands of years or longer), underneath Earth's crust, which allows the individual crystals to grow large by coalescing, like with like; thus, plutonic rock is coarse-grained rock. The rock is later exposed by erosion. A large body of this type of rock is called a pluton.
Is granite a plutonic rock?
Granite, coarse- or medium-grained intrusive igneous rock that is rich in quartz and feldspar; it is the most common plutonic rock of the Earth's crust, forming by the cooling of magma (silicate melt) at depth.
Why plutonic rocks have big crystals?
When magma cools underground, it cools very slowly and when lava cools above ground, it cools quickly. When magma and lava cool, mineral crystals start to form in the molten rock. Plutonic rocks, which cool slowly underground, have large crystals because the crystals had enough time to grow to a large size.
