Pumice is an igneous rock formed from volcanic eruptions. It is created when lava with high gas and water content rapidly cools and solidifies, trapping bubbles of gas inside. This rapid cooling results in a porous rock with a low density, making pumice able to float on water.

Which of Slate Granite Shale or Pumice is classified as a sedimentary rock?

Slate, granite, and shale are classified as metamorphic or igneous rocks, while pumice is classified as an igneous rock. Sedimentary rocks are formed through the deposition and solidification of sediment.

Is graphite igneous sedimentary or metamorphic?

Graphite is a metamorphic rock. It is formed from the metamorphism of organic sedimentary rocks, such as coal, under high temperature and pressure.


Is pumice a metamorphic rock?

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.


Does a rock go through the complete rock cycle by changing from igneous rock to sedimentary to metamorphic?

Yes, it can. However, an igneous rock can change to a metamorphic rock skipping sedimentary: the tectonic plates can push igneous rock deep into the ground, forming metamorphic rock. Sedimentary can form metamorphic, metamorphic can form magma or lava by melting and/or erupting and then turn into igneous. Igneous forms sedimentary with erosion, deposition compaction, and cementation.
