What else can I help you with?
You find a volcanic rock that is fairly smooth and only has a few small holes made when gas and water vapor escaped as the rock cooled you know that the rock can be classified as?
The volcanic rock can be classified as basalt. Basalt is a fine-grained igneous rock that forms from the solidification of lava flows. The smooth texture and small holes, known as vesicles, are characteristic features of basalt.
Where does pumice form?
Pumice forms when volcanic lava with high gas content rapidly cools and solidifies, trapping bubbles of gas within the rock. This process creates a lightweight, porous stone that floats in water. Pumice is commonly found near volcanic areas and can be produced during explosive volcanic eruptions.
Why does a rock with lots of tiny holes float?
A rock with lots of tiny holes can float because these holes decrease its density, making it less heavy than the same amount of water it displaces. This reduced density allows the rock to overcome gravity and float on the surface of water.
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.
Relate the pressure of the holes to the ability of pumice to float in water?
Many specimens have a high enough porosity that they can float on water until ... This is what produces the enormous rush of high-pressure gas from the vent. ... has a specific gravity of less than one, giving the rock an ability to float on water.
What can be inferred about volcanic rocks with gas holes in them?
It can be at least inferred that the rocks cooled quickly enough to retain the shape of the gas bubbles, and that they are therefore extrusive igneous rocks.

Pumice is an igneous rock full of tiny holes. Explain how these holes were produced?
how the holes may get there is from the hot lava or magma and since it is very hot it may cause the holes i am not to sure though about my answer.When rocks are heated to melting point, bubbles of gas can get trapped in them. When the rock cools, the gas is left as a hole. Volcanic rock is chock full of holes.

What has holes and can float in water?
a cork

things that have holes
