The video tutorial explains the formation of sedimentary rocks through the deposition and compaction of sediments over time. It highlights examples like sandstone and limestone, formed from sand grains and marine organism remains, respectively. The video also covers chemical sedimentary rocks, formed from mineral deposits left by evaporating water, such as in geothermal springs and cave formations. Finally, it introduces the topic of metamorphic rocks.
