HOTSPOT.pptx

the ppt is all about the lesson for hotspot

1. HOT SPOTS ACTIVITIES Formation of volcanoes in the middle of a plate

2. Objectives: Determine what hot spot is Relate hot spot with plate tectonics Recognize the results of hot spot activities.

3. The Hawaiian Islands are volcanic origin. Each island is made up of at least one primary volcano. The big Island, for instance is constructed of 5 major volcanoes: Kilauea, Mauna Loa, Mauna Kea, Hualalai , and Kohala

4. Hawaii is located in the middle of the north Pacific ocean. It is an archipelago with 8 major island, several atolls, numerous islands and seamounts. There are 5 active volcanoes in Hawaii

5. Mantle Plumes are tube like areas where heat and molten rocks in the mantle are rising towards the surface. A hot spot is the surface expression of the mantle plume.

6. The lithosphere moves slowly over the hot spot resulting to the formation of a chain of volcanoes. The volcano above the hot spot is considered as the newest or youngest and the most active.

7. The Hawaiian islands are products of hot spot activities in the middle of the Pacific Plate.

8. Hawaii – The Land of Paradise

9. Hawaii – The Land of Paradise

10. Mount Kilauea – most active volcanoes in the world.

11. Mauna Loa– world’s most active volcanoes.

12. Mauna Loa last erupted in 1984, and Kilauea ‘s last eruption was from 1983 to 2018. other volcanoes on Hawaii islands include: Mauna Kea, Hualalai , and Kohala.

13. Mauna Kea – world’s tallest volcano.

14. Mount Hualalai - third youngest shield volcano on Hawaii.

15. Kohala Mountain - The Big Island's oldest above-water volcano.

16. Seamounts are underwater extinct volcanoes.

17. Atoll is a ring shaped reef, island, or chain of island formed of coral. Atoll is a ring of coral formed around an extinct underwater volcano.
