pumice is volcanic ash and it is vesicular. meaning that it has lots of air bubbles in it making it even lighter. basalt is hardened lava. it was exposed and cooled rapidly.
== == Rhyolite, basalt, pumice, obsidian, andesite, dacite, tuff, welded tuff, scoria.
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.
Basalt has the highest density of the rock types mentioned.
No, pumice is an example of a felsic igneous rock. Mafic rocks, like basalt, have lower silica content and higher iron and magnesium content compared to felsic rocks, like pumice, which have higher silica content and lower iron and magnesium content.
some examples of igneous rocks are granite,basalt,and rhyolite and driolite

Diorite, rhyolite, pumice, and scoria.
Basalt and pumice.
No, basalt does not float in water because its density is higher than the density of water. Basalt is a dense volcanic rock formed from the solidification of lava, which causes it to sink when placed in water.
Obsidian, basalt, andesite, pumice.
No. They are black basalt.
pumice
Pumice is the result of extremely fast cooling lava.
They can be used for concrete.
Basalt does have a greater specific gravity. Granite is not as dense as basalt.
