Do igneous rocks float?
Most igneous rocks are denser than water, so they do not float. However, some types of igneous rocks, such as pumice, can contain trapped air bubbles which make them less dense than water, causing them to float.
What are the types of atoms in a pumice rock?
Pumice rock is primarily composed of silica (silicon dioxide) with traces of other elements such as aluminum, potassium, sodium, and iron. These atoms combine to form the unique porous and lightweight structure of pumice.
What is a rock formed from lava that cooled quickly and entrapped air and other gases and is similar to scoria?
The rock described is likely pumice. Pumice is a light-colored, frothy volcanic rock that forms when lava cools quickly, trapping air bubbles and gases. It is commonly used in horticulture and beauty products for its abrasive properties.
How are light colored igneous rocks different?
Light colored igneous rocks have a higher silica content and are known as felsic rocks. They have a lower density and are more common in continental crust. These rocks tend to be rich in minerals like quartz, potassium feldspar, and muscovite.
Can metamorphic rocks float?
The extrusive volcanic rock pumice can float on water. Other extrusive volcanic rocks are not so lucky.
Do igneous rocks float?

How do gabbro and pumice differ in texture and density?
Gabbro is a coarse-grained, intrusive igneous rock with a mafic composition. It typically has a dense texture and higher density due to its mineral composition. Pumice, on the other hand, is a light-colored, frothy volcanic rock with a vesicular texture that is formed from solidified frothy lava. It has a lower density compared to gabbro due to its high porosity from trapped gas bubbles.
What is the name of a igneous rock other than basalt and granite?
Diorite, rhyolite, pumice, and scoria.
What does the word felsic?
The word felsic is used to describe igneous rocks that are rich in silica and alkali feldspar. Such rocks tend to be light in color and have a lower density than other igneous rocks.

What is the name of a very porous igneous rock so light that it floats?
pumiceThe type of igneous rock that floats is called Pumice. It isn't lighter than other rocks, just less dense because it has lots of very small air bubbles trapped in it. You can see these if you look at the exterior of the rock.
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.

The extrusive volcanic rock pumice can float on water. Other extrusive volcanic rocks are not so lucky.
Which type of stone is lighter than water?
Pumice is a type of volcanic rock that is lighter than water. This is due to the presence of air bubbles trapped within the rock's structure, giving it a low density that allows it to float on water.
What is an example of an igneous rock besides granite and pumice and obsidian?
The word "igneous" comes from the Greek word for fire. Two other igneous rocks are Basalt dark grey to black, and Gabbro dark grey to black.
