Is lava a sedimentary rock or igneous?
The common usage of "lava rock" in the USA refers to a black rock with a number of visible bubbles or air pockets that is formed from cooled lava on the surface. Although lava rock is an igneous rock, it is not the same as the definition for the word igneous, which can also include igneous rocks which have solidified from magma below the surface.
What gets trapped while the magma or lava is cooling making holes in the igneous rock?
Gas bubbles.
What is an igneous rock that is gray and floats in water?
Pumice is a grey volcanic rock so full of gas bubbles that it is able to float on water.
Do igneous rocks float?
Vesicular pumice is an extrusive igneous rock that consists of a foam of mineral matter (usually silica-rich and glassy) enclosing bubbles of gas (usually carbon dioxide). The mineral material itself is denser that water, but the bubbles make the rock overall less dense than water, and it will float. Pieces of pumice may often be found washed up on beaches. Pumice is formed when magma of intermediate or felsic composition having a large proportion of dissolved gasses is simultaneously rapidly de-pressurised and rapidly cooled. The gasses exsolve like bubbles in warm and shaken soda-pop, and the mineral matter solidifies before the foam can collapse.
Is pluton a volcanic rock?
I learned about this when I was in the seventh grade. Pumice is volcanic. It was made by nature when lava and gases was thrown out of a volcano. As the gas bubbles escaped from the lava, it become frothy. When the lava cooled and hardened, the result was a very light rock material filled with tiny bubbles of gas.
Which type of igneous rock has air bubbles in it?
pumice
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.
When silica is in a rock does it make it lighter or darker?
Generally, igneous rocks with more silica are lighter in color.

Although lava rock is an igneous rock, it is not the same as the definition for the word igneous, which can also include igneous rocks which have solidified from magma below the surface.
Why are there holes in igneous rock?
The holes represent the bubbles of trapped and expanding gas that was present in the solidifying lava. They were essentially frozen in place.
What is a very light igneous rock containing air bubbles?
Pumice meets those requirements.
What is hardened lava called?
It is called igneous rock. Andasite,Basalt, and Dacite are igneous.
What gets trapped while the magma or lava is cooling making holes in the igneous rock?
Gas bubbles.
How the silica content of Molten material affects the color of igneous rock's?
The more silica contained in a rock, the lighter in color it will be.
What is an igneous rock that is gray and floats in water?
Pumice is a grey volcanic rock so full of gas bubbles that it is able to float on water.
What are vesicles in an igneous rock?
Vesicles are rounded spaces that appear in igneous rocks from the solidification of the magma around gas bubbles. Pumice, scoria, and vesicular basalt are igneous rocks that contain vesicles.
What happens if you put a igneous rock in water?
it would float because it is lighter than water.
