         <description><![CDATA[Sedimentary rocks form when layers of sediments (pieces of rocks, minerals, or organic matter) are compressed and cemented together over time. These rocks often contain fossils and form in layers called strata. Common examples include sandstone, limestone, and shale.]]></description>

         <description><![CDATA[Igneous rocks form when molten rock (magma or lava) cools and solidifies. The cooling process can happen either below ground (intrusive) or on the surface (extrusive). Examples include granite, obsidian, and pumice. The size of crystals in igneous rocks depends on how quickly the magma cools.]]></description>

         <title>Metamorphic Rock Formation</title>

         <description><![CDATA[Metamorphic rocks form when existing rocks are subjected to intense heat and pressure, causing changes in their mineral structure without melting completely. This process can transform sedimentary or igneous rocks into new forms. Examples include marble (from limestone) and slate (from shale).]]></description>
