sedimentray rocks

sedimentray rocks

Sedimentary rocks are formed from the accumulation of sediments that are compacted and cemented together over time.

Metamorphic rocks

Metamorphic rocks form from pre-existing rocks under high heat and pressure, changing their mineral composition and texture without melting

pumice rocks

Pumice rocks are light, porous volcanic rocks formed from frothy lava with trapped gas bubbles. They float on water due to their low density

lava rock

Lava rock is an igneous rock formed from cooled lava. It is porous and lightweight, often used in landscaping and horticulture for its unique texture and appearance.

igneious rocks

Igneous rocks are formed from the cooling and solidification of molten rock material, either below the surface (intrusive) or above ground (extrusive).

Granite rocks

A type of igneous rock with large grains formed from the slow cooling of magma underground. Made of quartz, feldspar, and mica.
