Why are extrusive rocks sometimes referred to as volcanic?
An extrusive rock is a rock that has been deposited at the earths surface as a liquid/fluid, coming to the surface form a depth through a fissure in the earth as a liquid/fluid. The most common type of liquid rock is a magma and magmas erupting at the surface are called "volcanoes" and thus the rocks are called "volcanic" rocks. However there are also volcanoes to be found that have nothing to do with molten rock magmas. These are called "Mud" volcanoes and they are caused by de-watering processes in rocks. The muds brought to the surface are also technically extrusive and these are NOT volcanic rocks.
What type of rocks are formed in volcanoes?
Volcanoes form igneous rock.
Are volcanoes the same as volcanic rock?
No...Volcanoes are openings in a planet's surface which allows for the flow of magma...volcanic rocks are simply rocks that originate from a volcano (igneous rocks)
What are rounded rocks that get flung by volcanoes?
Lava bombs.
What are small pieces of material that come from rocks or living things called?
They are called sediment.
Where does the volcanoes emit come from?
Volcanoes can emit lava,rocks,ash,fragments and molten rock.
Do rocks come from quarry?
Some rocks came from quarry, ergo not all rocks came from quarrying, rocks may came from different processes like sedimentation, there are also some rocks that came from volcanoes, these kind of rocks are called igneous rocks.
Are mountains the same as volcanoEs?
Similar but not the same, volcanoes erupt from magma and lava and rocks come out but not in a mountain
Pyroclasic materials from shield volcanoes?
Pyroclastic flows don't come from shield volcanoes. They come from cinder cone and sometimes composite volcanoes. Shield volcanoes only erupt runny lava.
What are rocks produced from lava and ash in volcanoes called?
volcanic rock
How can volcanoes cause melted rock?
Volcanoes do not cause rocks to melt, they are just the exit where melted rock come to the earths surface.
What are volcanic rocks like?
they have a redish tint to them and they smell like fire... they come out of volcanoes...
Are plutonic rocks igneous rocks that hardened on top of volcanoes?
No. Plutonic rocks are igneous rocks that hardened underground. Rocks that form on volcanoes are volcanic rocks.
How are volcanoes important in the formation of rocks?
Because the lava from volcanoes form igneous rocks
What kind of rocks are in volcanoes?
Igneous Rocks.
What are types of rocks formed by volcanoes?
Three different types of volcanoes are 1) Shield volcanoes; they are large mountains with gentle slopes. 2) Cinder cones volcanoes; they are small volcanoes made of hardened lava chunks called cinders. And the last one is 3) composite volcanoes; they are medium sized mountains made up of layers of lava that alternates with cinders. That is it.
What is a sentence with igneous sedimentary and metamorphic?
Igneous, sedimentaty and metamorphic are all types of rocks. You would just write sentences to describe each, like "Igneous rocks come from volcanoes" and "Sedimentary rocks come from sediment."
