What extrusive rock has a very low density?
An extrusive igneous rock has a very low density. This light colored rock is also known as a volcanic rock.
Is pumice an extrusive or an intrusive rock?
Pumice is Extrusive after it has been envelop from the volcanoes eruption! it can somehow be a intrusive but very "rare". It is however very light and bumpy felling!
What type igneous is pumice intrusive small crystal or extrusive large crystal?
Pumice is an extrusive igneous rock with a large number of small gas bubbles, resulting in its low density and light color. It forms from explosive volcanic eruptions where the lava cools quickly, trapping the gas bubbles within the rock.
Is basalt rock intrusive or extrusive?
Basalt is a common extrusive igneous (volcanic) rock formed from the rapid cooling of basaltic lava exposed at or very near the surface of a planet or moon.
Is pumice a metamorphic rock?
No, pumice is not a metamorphic rock. It is actually a type of igneous rock that forms from volcanic eruptions when frothy lava cools rapidly and traps gas bubbles inside, resulting in its characteristic porous texture. Metamorphic rocks are formed through the transformation of existing rocks under heat and pressure.
What extrusive rock has a very low density?

An igneous rock cooled very rapidly as it was formed because it was exposed to air What type of rock could it be?
it is an extrusive rock
Why do extrusive rocks cool quickly?
because the crystal in the rock is very small
Is gabbro an intrusive or extrusive?
Intrusive Igneous Rock , it is because gabbro has a very rough texture.Intrusive cools slowly and extrusive cools rapidly.
Do extrusive rocks cool quickly?
Extrusive rocks do cool quickly because either the crystals in the rock are very small or there are no crystals at all.
What Evidence Would You Look For If Attempting To Classify A Piece of igneous Rock as Extrusive?
Extrusive igneous rocks have very small crystal grains.
What kind of rock is formed when lava cools fast?
Extrusive igneous rock is formed from rapidly cooling lava.
What rocks are extrusive?
Extrusive igneous rocks are formed by magma. The magma is crystallized after being pushed to the surface of the Earth. They usually are very fine grained. A really common extrusive rock would be Basalt.
Can metamorphic rocks float?
The extrusive volcanic rock pumice can float on water. Other extrusive volcanic rocks are not so lucky.
A rock that cools very quickly so that few or no mineral grains form is?
You can describe the rock by the process that allowed it to cool quickly: "Extrusive" or you can describe it by its texture: "aphanitic". An extrusive rock tends to be aphanitic = Rocks formed from lava flows tend to have small crystals.
