Very porous rocks such as pumice can be very light and have the potential to float on water. Pumice is a volcanic rock.
The three types of naturally formed rock formations are igneous, sedimentary, and metamorphic rocks. Igneous rocks form from the cooling of molten magma, sedimentary rocks are created from the accumulation and cementation of sediment, and metamorphic rocks are formed from the alteration of existing rock through heat and pressure.

what are the ways in forming compound words
There are seven steps in the rock cycle.
Igneous rocks are formed through volcanic activity, where molten rock (magma) cools and solidifies either on the Earth's surface (extrusive igneous rock) or beneath the surface (intrusive igneous rock). These cooling processes result in the formation of crystals within the rock, determining its texture and composition.
rock cycle
The mineral composition and texture of the parent rock can influence the resulting minerals and texture of the metamorphic rock formed. Additionally, the temperature and pressure conditions experienced by the parent rock will determine the extent of metamorphism and the types of minerals formed.
Sedimentary rock is one of the three main rock groups (along with igneous and metamorphic rocks) and is formed in three main ways-by the deposition of the weathered remains of other rocks (known as clastic sedimentary rocks); by the deposition of the results of biogenic activity; and by precipitation from solution. Sedimentary rocks include common types such as chalk, limestone, sandstone, and shale. :)

.The oldest rock known today is the Igneous rock. .Igneous rock can be any colour..The word "Igneous" is a Greek word that means fire. Igneous rocks are formed by the cooling of molten rock, lava or magma. When magma solidifies in the earth they are intrusive, when lava cools outside the earth it is extrusive.
Three main ways and are classified accordingly. Igneous rocks form from molten material called magma.
