What igneous rock is light colored and has a lower density?
Shutup! Jew!
Why does pumice have a lower density than other igneous rocks?
Pumice has a lower density than other igneous rocks because it contains abundant air-filled cavities that make it porous and lightweight. These cavities are formed during the rapid cooling of volcanic magma, trapping air bubbles inside the rock. This porous structure gives pumice its low density compared to other igneous rocks that are more solid and dense.
Does obsidian rock float?
No, obsidian rock does not float as it is a dense and heavy igneous rock formed from cooled lava. Its high density causes it to sink in water.
Type of rock formed from molten rock?
Igneous rock is formed when magma cools and becomes solid.
What kind of rock is formed after a volcano erupts?
Extrusive igneous rock such as basalt, rhyolite, pumice, and obsidian.
What igneous rock is light colored and has a lower density?
Shutup! Jew!
How does the density of a light colored igneous rock differ from that of a dark colored igneous rock?
Normally, light colored igneous rocks are less dense compared to dark colored igneous rocks. This is because the light colored rocks have a less iron in them.

Is there such a thing as a floating rock?
Yes. It's called pumice, an extrusive felsic igneous rock with a density less than that of water.
Does obsidian rock float?
No, obsidian rock does not float as it is a dense and heavy igneous rock formed from cooled lava. Its high density causes it to sink in water.
What are the three families of igneous rocks?
The three families of igneous rocks are basaltic (mafic), andesitic (intermediate), and granitic (felsic). These families are classified based on their silica content and mineral composition, which in turn influence their color, density, and overall characteristics.
What describes rock that was formed when molten rock cooled down?
Igneous rock is formed.
Name an extrusive rock with a very low density?
Pumice is an extrusive igneous rock with a density less than that of water.
Is obsidian metamorphic igneous or sedimentary?
Obsidian is an igneous rock.
Type of rock formed from molten rock?
Igneous rock is formed when magma cools and becomes solid.
