Granite is a rock, whereas obsidian is a type of glass formed by cooling lava.
What else can I help you with?
Can Obsidian turn into Granite?
No, Obsidian and Granite are two different types of rocks with distinct properties. Obsidian is a volcanic glass formed from rapidly cooling lava, while Granite is an igneous rock made up of various minerals like quartz and feldspar. They have different mineral compositions and formation processes, so Obsidian cannot turn into Granite.
How does granite form into Obsidian?
Granite does not directly transform into obsidian. Obsidian is formed when lava cools very quickly, without giving crystals a chance to form. Granite, on the other hand, forms deep beneath the Earth's surface through the slow cooling and solidification of magma. So, while both are igneous rocks, they form under different conditions.
What is the same about granite and obsidian?
Obsidian and granite are both igneous rocks. Obsidian is of extrusive origin (which means the magma cooled quickly) and has a glassy texture. Granite is of intrusive origin (which means the magma cooled slowly) and is phaneritic, or coarse grained.y
Name 4 kinds of igneous rocks?
Examples of igneous rocks are pumice, obsidian, basalt, and rhyolite.
How is granite different from scoria pumice and obsidian?
Granite is an igneous rock that is coarse-grained and mainly composed of quartz, feldspar, and mica. Scoria and pumice are volcanic rocks with vesicular textures due to gas bubbles. Obsidian is a natural glass formed from rapidly cooling lava without crystallization.
What are the examples of ingeous rocks?
Obsidian, Granite, and i believe slate
What does granite obsidian and pumice share?
They are all Igneous rocks.
What type of rocks are pumice obsidian and granite?
Igneous rocks
What volcano does obsidian come from?
Obsidian is a felsic glass. At depth, it will crystallize to form granite. On the other hand it turns into perlite on reacting with water. At high grade it recrystallizes to form felsic glass.
What categories is granite pumice obsidian limestone sandstone marble in?
These materials belong to the category of rocks or stones, commonly used in construction and architecture. Granite, pumice, obsidian, limestone, sandstone, and marble each have distinct properties that make them suitable for different applications such as countertops, flooring, or sculptures.
What geological process is at work when obsidian or granite turns into sandstone or shale?
Compaction
What do obsidian pumice rhyolite and granite have in common?
Obsidian, pumice, rhyolite, and granite are all types of igneous rocks that form from the cooling and solidification of molten material from within or on the earth's surface. They have different mineral compositions and textures based on their specific formation processes.
