Because it is formed on the outside of the Earth (hense the 'ex')
This means that magma comes out of the Earth and then it cools to form pumice.
Pumice is Extrusive after it has been envelop from the volcanoes eruption! it can somehow be a intrusive but very "rare". It is however very light and bumpy felling!
Pumice is an extrusive igneous rock with a density less than that of water.

No, pumice is not a metamorphic rock. It is actually a type of igneous rock that forms from volcanic eruptions when frothy lava cools rapidly and traps gas bubbles inside, resulting in its characteristic porous texture. Metamorphic rocks are formed through the transformation of existing rocks under heat and pressure.
Pumice is an extrusive igneous rock with a large number of small gas bubbles, resulting in its low density and light color. It forms from explosive volcanic eruptions where the lava cools quickly, trapping the gas bubbles within the rock.
Extrusive
Pumice
No, pumice is an extrusive rock ejected into the atmosphere by volcanic eruptions.
Pumice is not a fossil because it is not an evidence of a previously living organism. Pumice is a vesicular extrusive igneous rock.

YES! It is an extrusive Igneous rock
Basalt, pumice, and obsidian are all extrusive igneous rocks which can appear as black rock.
Pumice is an extrusive igneous rock with a density less than that of water.
Pumice is classified as a felsic, glassy, highly vesicular, extrusive igneous rock.

The rock described is likely pumice. Pumice is a light-colored, frothy volcanic rock that forms when lava cools quickly, trapping air bubbles and gases. It is commonly used in horticulture and beauty products for its abrasive properties.
