What is the difference between basalt and obsidian?
obsidian is smooth but not basalt
Basalt and obsidian are extrusive igneous rocks. Gabbro is an intrusive igneous rock.
i think obsidian is a supercooled liquid of a magma.Its look like a glassy matter because is crystallised very faster than basalt and granite. Granite cools very slowly that's why it shows coarser grains and it crystallizes at very depth whereas basalt crystallizes at surface that's why it shows medium grain size.
Obsidian and Basalt are both Igneous rocks. They are made from hardened lava from volcanoes.
Yes the Obsidian does cool quickly and the vesicular basalt
Basalt, diorite, obsidian.
No. Pahoehoe forms basalt.
Obsidian has a higher luster(shinier) than coal, coal is organic, and coal is sedimentary and obsidian is igneous
gabbro basalt obsidian granite
Obsidian, basalt, andesite, pumice.
Basalt is a homogenous igneous rock. Gneiss is a foliated metamorphic rock.
Pumice is formed from frothy lava. Obsidian is not. Both have cooled rapidly from lava.
The difference between basalt lava and andesite lava is the chemical composition. Basalt lava comes from deep in the mantle of the Earth. Andesite's come from shallow sources near the continental plate margin.
Basalt, pumice, obsidian, rhyolite.
Basalt is a mafic extrusive igneous rock. Rhyolite is a felsic extrusive igneous rock.
Obsidian Basalt Rhyolite Andesite
basalt, granite, pumice, and obsidian
They are both Igneous. I hope this answered your question.!
Rhyolite, Obsidian,Basalt,Granite,and gabbro.
A few varieties including basalt, obsidian, and scoria.
Basalt has a higher degree of Calcium content compared to Andesite. Although Andesite has much more Sodium in it's contents than Basalt.
Granite, Basalt, Gabbro, and Obsidian
With the jade they used it to trade and buy goods, with the obsidian they made arrowjeads and knives, and with the basalt they made things such as tools from them.
the granite is more crystal than basalt
Jade masks read a textbook(i know you have one)
They traded honey and salt to get what they need such as jade ,basalt ,and obsidian.
Peridotite, andesite, pumice, rhyolite, obsidian, granite, and basalt.
basalt or obsidian or sandstone i learned it in college and now i am a geologist
A few would be obsidian, pumice, and basalt.
Gabbro is an intrusive rock, which means it formed underground. Basalt is an extrusive rock, which means it formed above ground .
Four examples of igneous rocks are pumice, granite, basalt, and obsidian.
Extrusive igneous rock such as basalt, rhyolite, pumice, and obsidian.
basalt, granite, rhyolite, andesite, gabbro, obsidian, scoria, pumice.
Examples of igneous rocks are pumice, obsidian, basalt, and rhyolite.
These are all formed by volcanic activity. Igneous
Extrusive igneous rock forms, such as basalt, rhyolite, and obsidian.
Basalt, Andesite, Rhyolite, Obsidian, Pumice, Tuff, Ash (Lava).
The texture is the main difference between Basalt and Scoria. Basalt is aphanitic, which means it is made of very fine grains. Scoria is vesicular, which means there are bubbles in the surface that occurred as the basaltic lava cooled. Both Basalt and Scoria are made of mafic minerals, mainly Ca rich Plagioclase Feldspar, Pyroxene, and Olivine, and both have extrusive origins, meaning they formed above the Earth's surface.
Basalt, Rhyolite, Obsidian and Andesite. There's many more but these are the main ones.
Granite,pumice,scoria,tuff,obsidian,basalt,gabbro,diorite and andesite.
Pumice, basalt, obsidian, and rhyolite are examples of extrusive igneous rocks.
Cooled lava forms extrusive igneous rock, such as rhyolite, basalt, obsidian, and pumice.
Here are some volcanic rocks: Basalt Andesite Scoria Obsidian Pumice Rhyolite
Basalt, rhyolite, obsidian, and pumice are examples of volcanic (extrusive) igneous rocks.
Obsidian, granite, basalt and pumice are all types of igneous rocks.
flint has an extremely bright shine
What kind of rock is limestone obsidian slate rock salt basalt granite sandstone gneiss marble and conglomerate?

Intrusive: Granite Diorite Gabbro Extrusive: Obsidian Basalt Rhyolite
Basalt, pumice, and obsidian are all extrusive igneous rocks which can appear as black rock.
Igneous rocks are formed from cooling lava. Some examples are obsidian And basalt.
