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.

Pumice obsidian and scoria are kinds of?
volcanic rocks formed from different processes. Pumice is a light and porous rock formed from foamy lava, obsidian is a dark volcanic glass formed from quickly cooled lava, and scoria is a dark, vesicular rock formed from gas-rich lava.
Give 10 examples of igneous rock.?
Basalt Granite Gabbro Pumice Rhyolite Obsidian Andesite Diorite Scoria Tuff
What are some names of extrusive igneous rocks?
== == Rhyolite, basalt, pumice, obsidian, andesite, dacite, tuff, welded tuff, scoria.
Obsidian pumice and scoria lack crystals because?
Obsidian lacks crystals because it is a type of volcanic glass that cools too quickly for mineral crystals to form. Pumice and scoria lack crystals due to their porous nature and high gas content, preventing the growth of crystalline structures during cooling.
Why doesn't granite have air holes like pumice and scoria?
Granite is an igneous rock that forms deep within the Earth's crust, where the slow cooling allows large mineral crystals to form without trapping air bubbles. Pumice and scoria, on the other hand, are formed from volcanic eruptions where the rapid cooling and depressurization trap bubbles of gas within the rock, creating the porous texture.
What are some exaples of igneuos rocks?
basalt, granite, rhyolite, andesite, gabbro, obsidian, scoria, pumice.
Is sandstone a scoria granite or pumice?
None of those. Scoria, Pumice and Granite are igneous rocks. Sandstone is sedimentary.

Examples of igneous rock?
Examples of igneous rocks include granite, basalt, and pumice. Granite forms from the slow cooling of magma deep within the Earth's crust, while basalt is associated with volcanic activity and forms from rapidly cooled lava. Pumice is a light-colored and porous rock that is often ejected during explosive volcanic eruptions.
