Pumice and granite are different types of rocks with distinct properties. Pumice is a lightweight, porous volcanic rock, while granite is a hard, coarse-grained igneous rock.
Pumice and granite are two different types of rocks with distinct properties and origins. Pumice is a volcanic rock that forms when lava with high gas content cools rapidly, trapping bubbles within the rock. It is lightweight, porous, and usually light-colored. Granite, on the other hand, is an igneous rock that forms from the slow crystallization of magma deep within the Earth's crust. It is a hard, coarse-grained rock composed mainly of quartz, feldspar, and mica.
