What is the difference between basalt granite and obsidian rocks?
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 rock has large mineral grains?
Fine grains of rocks are referred to as "clasts." The word "clast" comes from the Greek word "klastos," meaning "broken."
What are the colors and texture of both granite and basalt?
Granite and Basalt: 1. Granite is formed from magma that cooled slowly, so it has a coarse-grained texture. It may be pink, white-gray or light to moderate yellow. It contains the minerals feldspar, quartz and mica. Its mineral grains are similar in size. Granite is hard to scratch with a fingernail. 2. Basalt is formed from lava that cooled rapidly, so it has a fine-grained texture. Its mineral grains are so tiny that they can be seen only through a microscope. It may be black or dark green. It contains the minerals feldspar and olivine. Like granite, basalt is hard to scratch with a fingernail.
Is granite gneiss marble limestone shale or basalt an igneous rock?
These are sedimentary rocks. Sandstone is made of compressed grains of rock and sand. Shale is made of compressed bits of mud and clay. Limestone is made of compressed pieces of forms of calcium carbonate.

Why is the texture of obsidian is best contain few or no minerals grains?
Obsidian cools so quickly the mineral grains do not have time to form.

Does obsidian rock contain few or no mineral grains?
That is correct.
Which rock has large mineral grains?
granite
Which rock is very smooth and has no visible mineral grains?
Glassy textuered rocks, such as Obsidian.
Is granite a phaneritic rock?
Granite is a phaneritic rock. Phaneritic rocks are coarse-grained, and they have visible crystals. Other phaneritic rocks include diorite, gabbro, and periodite. These rocks are also intrusive because they cool slowly.
What rock is similar to basalt in mineral make up is intrusive and has coarse grains?
It is Gabbro
Why do they call granite granite?
Granite is actually made of mineral grains that are stuck together and solidified. It appears that the name "granite" comes from the based word "grain".
