These particles accumulate in layers and are compacted and cemented together to form sedimentary rocks.

These particles accumulate in layers and are compacted and cemented together to form sedimentary rocks.

The eroded materials (sediments) are deposited in layers, often in bodies of water. Over time, these sediments accumulate and compact, eventually forming sedimentary rocks like sandstone or shale.

Sedimentary and igneous rocks can be transformed into metamorphic rocks through heat and pressure. This process, called metamorphism, alters the mineral composition and structure of the original rock.

Metamorphic rocks, as well as igneous and sedimentary rocks, can eventually melt into magma if subjected to sufficient heat.

When the pressure becomes too great, the magma is forced through fissures or a volcanic vent, reaching the surface.
