What are some names of extrusive igneous rocks?
== == Rhyolite, basalt, pumice, obsidian, andesite, dacite, tuff, welded tuff, scoria.
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.
What is the densest rock basalt limestone marble or shale?
Basalt has the highest density of the rock types mentioned.
Is pumice in a example of a mafic igneous rock?
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.
What has a lower density rhyolite or basalt?
Ryholite due to the reason that this rock is made up of lighter elements than that of Basalt
Why is basalt heavier than?
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.
Name 4 kinds of igneous rocks?
Examples of igneous rocks are pumice, obsidian, basalt, and rhyolite.
What is the name of a igneous rock other than basalt and granite?
Diorite, rhyolite, pumice, and scoria.
What is example of igneous rock?
Basalt and pumice.
Does basalt float in water?
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.
Name a volcanic rock?
Obsidian, basalt, andesite, pumice.
Are the Hawaiian island rocks light pumice?
No. They are black basalt.
What is a 6 letter word for lava rock?
pumice
Which is fomed by fast cooling lava--pumice granite or basalt?
Pumice is the result of extremely fast cooling lava.
What is one way basalt and pumice are used today?
They can be used for concrete.
Basalt has a greater specific gravity than granite?
Basalt does have a greater specific gravity. Granite is not as dense as basalt.
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.
