Is obsidian metamorphic sedimentary or igneous?
Obsidian is an igneous rock.
Obsidian is classified as igneous rock, solidified from molten material.
Obsidian is an extrusive igneous rock, formed from rapidly cooling lava.
Obsidian is an extrusive igneous rock, usually a shiny black volcanic glass.
Obsidian is an igneous rock due to the nature in which it was formed. Obsidian is formed when lava from volcanoes is hurled high into the air, cools quickly upon falling and becomes the glassy rock known as obsidian.
Igneous: * Obsidian * Granite * Diorite * Gabbro * Pumice * Basalt Metamorphic: * Slate * Phyllite * Gneiss * Mica schist * Marble * Quartzite * Granulite Sedimentary: * Limestone * Sandstone * Shale * Chert * Mudstone * Chalk
its igneous and sedimentary and metamorphic
its not a sedimentary, igneous, or metamorphic rock its a mineral
Lepidolite is a mineral and is not classified as igneous, sedimentary, or metamorphic.
igneous, solidified from molten state: granite, basalt, obsidian sedimentary, settled out erosion or biological products: sandstone, limestone, lignite, mudstone, shale, flint metamorphic, modified by heat and/or pressure: marble, slate, coal, schist, gneiss, quartzite
A rock can change: * from metamorphic to igneous, sedimentary, or a higher grade metamorphic rock * from sedimentary to igneous or metamorphic rock or to a different sedimentary rock * from igneous to sedimentary or metamorphic rock.
53% igneous, 23% metamorphic, and 24% sedimentary
Talc is a mineral and is not classified as metamorphic, sedimentary, or igneous as are rocks.
Graphite is a mineral, not a rock that is classified as metamorphic, igneous or sedimentary.
No. Obsidian is an extrusive igneous glass.
Osidian is a igneous rock
As a mineral, it is not classified as igneous, metamorphic or sedimentary, though most often found in sedimentary rock.
Igneous-sedimentary weathering/erosion Igneous-Metamorphic high pressure and heat
igneous rocks started as melted lava and cooled to be rocks. Metamorphic rock started as a sedimentary rock, and was heated up and put under pressure to create the metamorphic rock. Classic example - igneous = obsidian. Metamorphic = marble (marble is limestone that's been heated and squeezed a lot).
obsidian is an igneous rock, it is not formed from sediment, or a rock going under heat and pressure for the second time it is formed when a volcano erupts and it cools very quickly giving it a smooth glossy surface like glass.
Calcite is a mineral and not classified as metamorphic, sedimentary, or igneous, although it is usually associated with sedimentary rock formations.
igneous is black and smooth metamorphic is magnetic and sedimentary is used as cement
== == Quartz is actually a silicate mineral that appears in metamorphic, sedimentary, and igneous rocks.
Turquoise occurs in sedimentary or metamorphic rocks near or at the contact with igneous intrusives.
Metamorphic rocks can form from both igneous and sedimentary rocks
Amethyst is actually a variety of quartz, and as a mineral, is not classified as igneous, metamorphic, or sedimentary as are rocks.
Quartz is actually a silicate mineral that appears in metamorphic, sedimentary, and igneous rocks.
Igneous Rock,Sedimentary Rocks,Metamorphic Rocks Igneous made from cooled magma Sedimentary made from sediments Metamorphic made from either sedimentary or igneous
igneous rocks mix with metamorphic rocks and they combine together to make a sedimentary rock. the three themes of science rocks are metamorphic,igneous, and sedimentary.
Neither. Both pumice and obsidian are igneous.
it is igneous
It is generally igneous, but can be found in metamorphic rocks.
Sedimentary, igneous and metamorphic.
Pressure compresses the sedimentary and igneous rock(s) tightly and forms metamorphic rock.
Igneous: Obsidian, Pulmice (PUM ISS) Sedimentary: Sandstone, Siltstone
Does a rock go through the complete rock cycle by changing from igneous rock to sedimentary to metamorphic?
Yes, it can. However, an igneous rock can change to a metamorphic rock skipping sedimentary: the tectonic plates can push igneous rock deep into the ground, forming metamorphic rock. Sedimentary can form metamorphic, metamorphic can form magma or lava by melting and/or erupting and then turn into igneous. Igneous forms sedimentary with erosion, deposition compaction, and cementation.
Igneous rock or sedimentary become metamorphic by " The Rock Cycle ".
Jade is metamorphic.
It is a Sedimentary rock
Topaz is igneous
Sedimentary and Metamorphic rocks becomes igneous rocks when they get melted with the magma then later cool and crystallize.
Metamorphic rocks originate as igneous and sedimentary rocks, but have been changed by heat and pressure.
Igneous Rocks are formed. Obsidian is a volcanic glass, go to wikepidiea and search "list of rocks" and it will come up with all the different igneous, metamorphic, and sedimentary rocks and what they are.
Feldspar is a mineral. It can be found it sedimentary and metamorphic rocks though.
Quartz is a mineral, not a rock. It is found in igneous, sedimentary, and metamorphic rocks.
