    Study Notes

    Geological Processes of Hawaiian Archipelago

    • The Hawaiian archipelago is expanding due to volcanic activity, specifically the movement of the Pacific plate over a hotspot, a zone of molten rock in the Earth's mantle.

    Hawaiʻi Volcanoes National Park

    • The park includes two active volcanoes: Kīlauea and Mauna Loa.

    Volcanic Eruption

    • Molten lava flows from a volcanic eruption, which forms lava flows.

    Expansion of the Archipelago

    • The Hawaiian archipelago is expanding due to the natural process of volcanic activity, specifically the movement of the Pacific plate over a hotspot.

    Location of the Hawaiian Hotspot

    • The Hawaiian hotspot is located beneath the island of Hawaiʻi.

    Slower Moving Lava

    • The slower moving lava on the surface of the flow initiates a process called crust formation.

    Crust Formation

    • The slower moving lava hardening on the surface of the flow forms a crust.

    Lava Tubes

    • When the lava eventually flows out of the lava tube, it leaves behind a hollow tube or channel.

    Hawaiʻi Volcanoes National Park Attractions

    • Visitors can witness the crater and lava lake at the summit of Kīlauea volcano in Hawaiʻi Volcanoes National Park.

    Effects of Slower Moving Lava

    • The slower moving lava on the surface has an insulating effect, allowing the molten lava below to remain hot and fluid.
