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.
What else can I help you with?
What is the difference between basalt and obsidian?
Basalt is a dark-colored volcanic rock formed from the rapid cooling of lava, while obsidian is a dark volcanic glass formed from the rapid cooling of lava with high silica content. Basalt has a crystalline structure, while obsidian is amorphous and often exhibits conchoidal fracturing. Basalt is typically denser and more resistant to weathering compared to obsidian.
Which rock has large mineral grains granite obsidian basalt or pumice?
Granite has large mineral grains compared to obsidian, basalt, and pumice. Granite is an intrusive igneous rock that forms deep within the Earth's crust, allowing for the growth of large mineral crystals due to slow cooling. Obsidian, basalt, and pumice are extrusive igneous rocks that cool quickly at the Earth's surface, resulting in smaller mineral grains or a glassy texture.
Give 10 examples of igneous rock.?
some examples of igneous rocks are granite,basalt,and rhyolite and driolite
What are some igneus rocks?
some igneus rocks are Granite,Basalt,Pumice,Obidan,and Rhyolit.
What are examples of igneous rocks and its chemical formula?
Examples of igneous rocks include granite, basalt, and obsidian. The chemical formula for granite is roughly SiO2 (silicon dioxide), for basalt it's typically SiO2, Al2O3, FeO, MgO, CaO, and for obsidian it's SiO2 with minor impurities giving it a glassy texture.
Name 4 kinds of igneous rocks?
Examples of igneous rocks are pumice, obsidian, basalt, and rhyolite.
What are three types of igneous rock?
Three types of igneous rocks are basalt, granite, and obsidian. Basalt is a dark-colored fine-grained rock, granite is a light-colored coarse-grained rock, and obsidian is a natural glass formed from rapidly cooled lava.

Which rock has large mineral grains granite obsidian basalt or pumice?
Granite has large mineral grains compared to obsidian, basalt, and pumice.

Obsidian, basalt, and pumice are extrusive igneous rocks that cool quickly at the Earth's surface, resulting in smaller mineral grains or a glassy texture.
