∙ 7y agoThe 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.
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.
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.
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.
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.
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.

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.

Animals float due to their body composition and density. Some animals have built-in flotation devices, such as air sacs or blubber, while others have light bodies or special adaptations that allow them to stay buoyant in water. Additionally, animals may adjust their body position or use their limbs to help them stay afloat.
a cork
it has holes in it and has kelfrigis
Boats that get holes in them.
