The air and gases escape from the lava as it cools. This makes the little holes that you see. The rock is called pumice.

Does igneous rocks absorb water?

igneous rocks do absorb water because of all the pores ,cracks, and holes in them. The holes will absorb the water and the water will get trapped in the rock there for igneous rocks do absorb water.


What causes air holes in igneous rocks?

Air holes in igneous rocks are typically caused by gas bubbles trapped within the magma during the rock's formation. As the magma cools and solidifies, these gas bubbles can become trapped within the rock, creating voids or cavities. These voids are known as vesicles and can be filled in with other minerals or remain empty, forming empty holes in the rock.


What causes igneous rocks to become magma?

Cooling to a solid.


Are igneous rocks waterproof?

Igneous rocks are generally not waterproof because they are porous due to the presence of tiny spaces or holes where water can seep through. However, some igneous rocks, such as granite, have low porosity and can be relatively resistant to water absorption.


What are two ways you could identify igneous rock?

When it has holes and small rocks inside the rock


What is the main type of energy used to help convent metamorphic rocks into igneous rocks in the rock cycle?

The main type of energy used to convert metamorphic rocks into igneous rocks in the rock cycle is heat. The increase in temperature causes the metamorphic rocks to melt and then solidify into igneous rocks.


When molten rocks cools what rocks form?

igneous rocks


What causes sedimentary or igneous rocks to turn into metamorphic rock?

Heat and Pressure.


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.


What are igneous rocks that form over the surface?

Rhyolititcen rocks.


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.


What do you call rocks that have been formed from the hot molten material within the earth's crust that has cooled and hardened?

Igneous rocks are formed by the solidification of molten materials.
