What are the 3 newest rocks please!?

The three newest types of rocks typically refer to volcanic rocks that are formed through recent volcanic activity. For example, the lava flows from the 2021 eruption of La Soufrière in St. Vincent produced fresh basaltic rocks. Similarly, the 2020 eruption of the Fagradalsfjall volcano in Iceland has resulted in new basalt formations. Lastly, the ongoing eruptions at Kilauea in Hawaii continue to generate new lava rock.
