Obsidian and Basalt are both Igneous rocks. They are made from
hardened lava from volcanoes.
Basalt and obsidian are extrusive igneous rocks. Gabbro is an intrusive igneous rock.
Basalt, diorite, obsidian.
gabbro basalt obsidian granite
Obsidian, basalt, andesite, pumice.
obsidian is smooth but not basalt
basalt, granite, pumice, and obsidian
They are both Igneous. I hope this answered your question.!
A few varieties including basalt, obsidian, and scoria.
Extrusive igneous rock such as basalt, rhyolite, pumice, and obsidian.
Extrusive igneous rock forms, such as basalt, rhyolite, and obsidian.
Basalt, Rhyolite, Obsidian and Andesite. There's many more but these are the main ones.
Igneous rock formed at or near the surface is referred to as extrusive igneous rock, such as basalt and obsidian.
A few would be obsidian, pumice, and basalt.
basalt or obsidian or sandstone i learned it in college and now i am a geologist
Basalt, pumice, and obsidian are all extrusive igneous rocks which can appear as black rock.
Extrusive igneous rock forms from the solidification of lava. Rocks such as rhyolite, pumice, obsidian, and basalt.
Basalt, Andesite, Rhyolite, Obsidian, Pumice, Tuff, Ash (Lava).
An igneous rock is a rock formed by the solidification of molten lava. some examples of this rock type are: Pumice, Obsidian, Basalt, Andesite, and Ryholite.
Extrusive igneous rock. Obsidian and basalt are examples of extrusive igneous rocks formed from the solidification of lava.

Cooled lava forms extrusive igneous rock, such as rhyolite, basalt, obsidian, and pumice.
Basalt, rhyolite, obsidian, and pumice are examples of volcanic (extrusive) igneous rocks.
Rocks formed from solidified molten rock are classified as igneous rock. Examples would be basalt, granite, gabbro, pumice, obsidian, and rhyolite.
An igneous rock is a rock that is made from heat , and the different types of igneous rocks are Obsidian , Granite , Basalt , Pumice and Gabbro.
Igneous rocks are formed from molten rock cools and hardens. Can be intrusive or extrusive. Examples are granite, basalt, obsidian, and pumice.
Yes the Obsidian does cool quickly and the vesicular basalt
intrusive: gabbro, granite, diorite extrusive: andesite, obsidian, rhyolite, basalt
Igneous rocks are those that have solidified from molten rock, such as pumice, granite, basalt, obsidian, rhyolite.
Extrusive Igneous rocks, eg basalt, pumice, obsidian, tufa etc., are associated with volcanoes.
Examples of igneous rock include: pumice basalt gabbro diorite granite rhyolite obsidian scoria
Basalt and rhyolite are examples of extrusive igneous rocks. Also, pumice, scoria, obsidian, tuff, ignimbrite,....
No. Pahoehoe forms basalt.
Obsidian is a volcanic glass, so the main component is silica. It is 70-75% SiO2, plus MgO, Fe3O4. Mainly from molten granite, carbonated basalt and quartz for shininess.
Granite, rhyolite, obsidian, basalt, pumice, gabbro, diorite; all examples of igneous rock that by definition forms from the cooling of molten rock.
Magma is molten rock which rises from the mantle and into the crust and may solidify into igneous rock underground (e.g. granite or gabbro) or solidfy above ground (basalt, rhyolite, obsidian). === ===
All rocks that are made from cooled magma are called igneous rocks. Some common examples include Obsidian, Granite, and Basalt.
Magma a hot molten underground rock. Igneous rocks are the solidified form of magma. Examples of these are granite, peridotite, basalt and obsidian.
That rock was not Basalt, it was different. This is not a diamond, just a normal Basalt.
Yes, Obsidian is an extrusive rock.
Extrusive igneous rock is formed from rapidly cooled lava at Earth's surface. Examples are obsidian and basalt.
Basalt is on of the many rocks that is black, obsidian (a volcanic glass) is another.
Basalt is an igneous rock, but not all igneous rock is basalt. Marble is an example of a metamorphic rock.
Basalt, pumice, obsidian, rhyolite.
Obsidian is an extrusive felsic igneous rock.
Obsidian is in the Igneous rock group.
Obsidian is an igneous rock. So the answer is YES.
how can a blue obsidian rock be blue
Obsidian, pumice, rhyolite, basalt, basaltic glass, andesite, scoria, granite, gabbro, diabase, pegmatite, diorite, peridotite, dunite, vesicular rhylolite, vesicular andesite and vesicular basalt are all igneous rocks.
Basalt is an extrusive igneous rock.
